Odor control can be crucial for indoor growers as it helps keep prying noses away and maintain the privacy of your space.A carbon filter is a highly effective method that can eliminate over 90% of smells from an indoor grow space.For that reason it’s a good idea to get a activated charcoal filter and fan, so you can be sure that the carbon filter and fan will work together to keep odors from leaking out of the grow tent.ECO FARM CARBON FILTER If you are on the lookout for the carbon filter for grow tent, this is one option that should be on the top of the list.Its best asset is perhaps the ECO Farm carbon filter, which provides it with the ability to provide as much as 99.8% filtered air flow.Protects from chemical irritants and eliminates odors- from pungent indoor grow operations to bathrooms, basements and kitchens.Absorbs odors from pets and smoking as well.Eliminate some of the most undesirable odors, pungent smell and particulates from indoor grow tent, hydroponics grow room.Item can be used as intake or exhaust filter in a variety of setups including use with 6 inch inline fan and duct fans, intake and exhaust fans, air exchange fans, ventilation ducts, and other accessories.So, overall, it works great as long as it comes in looking great.If not, you’ll have to return it and try again!VIVOSUN AIR FILTRATION GROW KITS With VivoSun, your days of buying and returning parts that are not compatible with your ventilator are over.These parts include a powerful inline fan which runs on p68 watts, 0.62A and a noise level of 49dB.
Energy efficient greenhouses cost less to operate, and in some cases perform better than less-efficient facilities.When you think about the fluctuating and (usually) rising costs of energy, it only makes sense to ensure that your greenhouse is as energy efficient as possible.A whopping 72% of growers place energy efficiency in lighting as a top priority in grow light purchasing decisions.The same study revealed that lighting accounts for more than 50% of energy costs for 26% of research participants.When you increase energy efficiency in lighting, you tackle one of your biggest expenses.Here’s one more statistic: 72% of growers also listed light intensity as a major consideration when purchasing grow lights.Good artificial lighting is a close match to sunlight, but artificial lighting can go even a step further and feed the plants with wavelengths that could grow plants even faster and more nutrient dense than when grown under sunlight.Stop Measuring Light Quality in WattsFor a long time, more watts meant higher light intensity.In contrast, quality LED lights run at an efficacy of up to 3.0 micromoles per joule.In the modern market, the only reason to look at watts is to determine whether your current lighting system is using more energy than it needs to.The Choice of LightsUnderstanding how much light a plant needs in each of its growth phases gives input to how many lights should be used, what kind of lights, and how they should be positioned.
In this article, we will discuss what LED Grow Lights are, why they are beneficial, and compare two LED grow lights for sale on the market.For decades, indoor growers have relied on artificial light sources such as HID, High-Pressure Sodium, and Fluorescent to mimic the sun’s rays in an indoor environment.It’s a technology that’s been around for decades, mostly as instrument panel indicator lights, but only recently are LEDs being applied to higher intensity light uses such as indoor growing.The primary benefit of LED grow lights over the more established light sources is significantly reduced heat and reduced power consumption.Because they produce less heat than the more commonly used HIDs, then they are more energy efficient and require significantly less expense to ventilate and cool.However, choosing and buying a LED grow light based on PAR alone is not the best idea.PAR or Photosynthetically Active Radiation denotes the usable light that the plants will absorb.Starting with the quality of the components and materials and going through the actual design (fans, heat sinks, chip density).There are certainly better quality LED lights, but because they cost ten times as much, I feel the lights listed below give you the best results for your money.These LED lights are also some of the best-selling grow lights on Amazon.
I know you want something worth your money, worth spending a dime on that will do a pretty good job not crack your head on when it can barely do a thing!Just kidding!Most of the presses out there are pretty much legit and truly worth your money what the issue could be is the extra zeros that it asks for and which one would be ideal for you.This makes it difficult to provide a blanket statement regarding the best pressure to use.The flower requires more pressure than kief or hash.However, this article isn't about figuring out what the optimal pressure is for rosin pressing, it's about figuring out which press is the best bang for your buck.From that lens, the thing to think about it what kind of pressure "options" does our rosin press provides us with.The trade-off here is partially the manual effort you have to put in, but more-so about capacity.The added bonus to using an electric press is that there's no need for external pumps or compressors.TimeMost rosin presses in this day and age will have a digital timer so you can "set it and forget it".Ultimately the "time" part of the rosin press equation, shouldn't impact our buying decision much, it's more likely we'll focus on heat and pressure.ECO FARM ROSIN PRESSECO Farm Canada Inc supplies the finest brands of indoor cannabis products for growing massive yields and healthy cannabis crops.
Plus—as you’ve undoubtedly heard by now—LED lights to accomplish all this while using limited energy and emitting very little heat.However, in order to use all these benefits to their fullest potential, you must determine the optimum placement in relation to your canopy.PPFD is an important metric because it helps growers accurately measure the light intensity for photosynthesis at the canopy level.It is also important because lights placed too close to the canopy can cause burning, bleaching, stunted growth, or discoloration.How far should LED grow lights be from plants?A general principle for placing LED grow light is 18 inches to 42 inches above the canopy of your plants but the accurate distance is determined by the type of LED light, Wattage it uses and the growth stages of plants along with their types.These can be brought further closer during the vegetative stage, about 24 inches from the canopy and 18 inches during the flowering or bloom periods till the maturity of the plant.LED Grow Light Distance ChartHow Far Should LED Grow Lights be for Flowering PlantsAs plants grow, their needs change.It is also important to consider the power output of the grow light — this usually is related to the wattage of the light source, which is a primary factor in determining the optimal distance for LEDs when starting the growing process.Plant growth can roughly be divided into three different stages – Seedling, Vegetative, and Flowering stages.This means once healthy roots are firmly established, it’s time to increase the intensity and lower the lights.Seedling StageDuring the initial stage as seedlings, LED grow lights should be placed higher up from the plants to avoid drying out the soil.Some growers may be tempted to blast seedlings with a high-intensity light to promote faster growth, however, this will not help until the plants become established.Strong, healthy stems and roots are key for a successful and repeatable yield.While increasing light intensity promotes growth in the vegetative stage, it is important to closely monitor your plants, making sure to look out for adverse symptoms caused by too much light or not enough.Flowering StageFlowering is the final stage of a plant’s growth cycle — during this time fruit production and stem growth accelerate.
Choosing the carbon filter right size for your grow space is SO important.There are so many options available that it can be hard to find a carbon filter that’s the right size for a small 4×4 tent.CFMAs discussed, choosing the right size carbon filter to cover the overall space of your grow room is the most important deciding factor.You NEED to get a filter that will match the area of your groom room.In order to buy the correct grow tent ventilation or carbon filter size , you’ll need to calculate the volume of the grow tent or grow room.To be safe, purchasing carbon air filters that cover 20% more than the CFM actually needed.For example, if you have a grow tent that is 4' x 4' x 7', then the volume would be (4x4x7) = 112 cu./ft.Volume To CFM — Your exhaust fan should be able to exhaust the equivalent of your growing environment’s volume in two minutes, or one minute if you are having issues with high temperatures.Assuming we are not having issues with heat, the growing environment volume from our example is 112 cu./ft., which means we need to exhaust 112cu.ft.And same goes to other heat generative devices like motors etc.For each 1000W lamp power, add ~10% to the fan cfm requirement.If you have 4 fans of 1000W each, and if the generic calculations say a 200CFM, then the above total will be — Fan Size= (200 CFM + (200×40%))= 280 CFMWhat size carbon filter for a 4×4 tent?In most cases, a 4 inch carbon filter will be more than enough for a 4×4 tent.Its best asset is perhaps the ECO Farm carbon filter, which provides it with the ability to provide as much as 99.8% filtered air flow.Protects from chemical irritants and eliminates odors- from pungent indoor grow operations to bathrooms, basements and kitchens.
It’s one of the questions growers most ask, we get asked it daily, sometimes more than once!So let’s settle the evergreen question of “How close to put grow lights to my plants?”Firstly let me start by saying it depends on a few factors such as;Type of light you use (HPS, CFL or LED)Wattage/power of the light you useThe temperature just above the canopy of your plantsThe type of plants you’re growingAmount of vertical space you have availableA good rule of thumb to follow if you’re in doubt is 1-2ft away from the canopy of your plants.You want to to be close up during the early stages of your plants life to avoid stretching and as they get bigger you can risk having the HPS light a little further away.What distance should my LED grow light be from my plants?LED grow lights don’t produce anywhere near as much heat as HPS systems so you can theoretically get them much closer to your plants without running the risk of damaging them.LED lights are more penetrating than HPS lights however different brands of bulbs / kits have different qualities, view angles & coverage areas.In general you want to place your LED grow light 6-12 inches above your canopy although different manufacturers have different guidance depending on how they are built.A good rule of thumb to follow when figuring out the distance to put your LED light from your plants is to get them as close as possible without compromising the coverage area and leaving plenty of room for them to grow into.How far away should I put my CFL grow light from my plants?CFLs are like LEDs but they are nowhere near as penetrating as HPS or LED lights.The biggest problem of all is stretching, this is when your plant puts extra effort into growing taller so that it can be nearer the light source.Because they put all their energy into getting closer to the light they don’t put as much energy into producing fruit, this will lower your yields by as much as 30%, let me repeat, you could be getting 30% less fruit simply because you positioned your grow light to far away!What happens if my grow light is to close to my plants?On the flip side you can also cause problems to your plants if the grow light is to close.Look for a full spectrum grow light that will cater towards every stage of growth for your plants.Whether you’re growing a hobbyist, or for your professional needs, a 600-watt light is the great in-between size.ECO Farm ECOM 650W SEOUL LED Grow Light BarDesigned with SEOUL chip, higher light intensity, less light decay, better lumens and PAR values than ordinary leds.Utilizing Scynce’s patented optics for incredible canopy penetration, the Raging Kush was engineered to meet the needs of large horticulture operations.
Find out how to choose the best grow lights for seedlings!Was your recent attempt to grow seedlings did not go as you hoped?If you experienced having leggy and weak sprouts after germinating your seeds, then the problem is most likely the light they received right after the moment they surfaced.Now, you might be wondering do you really need a grow light to start seeds indoors?A direct and simple answer is, seedlings need more light than full-grown plants, It’s ideal for seedlings to get as much as 14 to 16 hours or at least 8 hours of exposure to light in a day and that is actually more than a whole day of sunlight.Types of grow lightsYou can choose between fluorescent, LED, and high-intensity discharge (HID) bulbs, each of which has its own pros and cons.However, they usually require bulky external ballasts (like, for example, overhead shop lights) so aren't as easy to work with as incandescent and LED bulbs.Cool white bulbs are a good source of blue and yellow-green light, but are a poor source of red light.If you are growing seedlings under two-bulb fluorescent fixtures, you can usually achieve a good color balance by combining one cool white and one warm white bulb.Full-spectrum fluorescent bulbs produce a balance of cool and warm light that replicates the natural solar spectrum, although these are less energy efficient than other fluorescent bulbs and tend to produce more heat.For a typical seedling tray, that means using 2 bulbs, ideally with a reflector hood over them to focus all the light on the seedlings below.LED grow lightsUnlike other bulbs which produce light across a broad spectrum, light-emitting diodes (LEDs) give off light within a narrow band.The result is a purple glow that not everyone likes.Full spectrum LED grow light provides plants in all stages from veg to flower with everything they need in the natural sunlight.LEDs are mercury-free and won't shatter like glass.These bulbs are long-lived (up to 5x longer than fluorescent lamps) and very energy efficient, but they cost considerably more than fluorescent bulbs.Research is still ongoing to determine which combination of light frequencies are best for plant growth and how LED grow lights compare to fluorescent bulbs in producing healthy seedlings.
Plants need enough time to grow and develop correctly, and time is what can tell a nice productive plant from a pile of branches lacking in both foliage and yield.Today we’re going to talk about normal growth times and the different stages that your plants will go through.Maybe some of these questions sound familiar to you;How long does cannabis take to germinate/flower?What can I do to make my plants flower earlier?Can I speed up the growth?Which is the fastest, highest yielding plant?These questions are probably best answered with the age old phrase, time is gold.The techniques for germination are very diverse, from the typical technique that uses a napkin or wet paper, to the use of stimulators or planting the seed directly in soil, on a jiffy disc or in a glass with water.The best thing to do is to use the napkin or wet paper and, as for the time, to re-emphasize that it is relative.It will not only depend on the conditions of water, humidity or oxygenation, we will also have to consider the quality of the seed, its fertility, the variety or strain in question.Sometimes we find seeds that can take 5,10 or 15 days to arrive.The Growth or Vegetative StageSecondly, we find the growth or vegetative phase.
If you’re in a state where growing your own cannabis is legal, you’ve likely considered cultivating your own marijuana.However, growing cannabis at home does have its challenges.Cannabis has a very strong odor that can draw the ire of neighbors and marijuana plants may attract pests like mites and gnats.Outdoors, it’s difficult or impossible to control the environment to make sure the number of daylight hours, amount of water, the soil, and the nutrients are all what the plant needs.Daylight hours are impacted by the time of year, and therefore there isn’t a good way to stimulate 24 hours of light to encourage faster growth during the vegetative stage.This helps produce more flowers and can encourage larger buds.Keep an Eye on the Plants at All TimesOutdoor plants are usually close to the home, but that doesn’t mean it’s possible to check on them as frequently as it would be indoors.
Although they would not have been a reasonable choice for marijuana growers five or ten years ago, they are becoming more popular every day.HID lights will become very hot, but good LED lights feel cool when you touch them, even after running for several hours.LED lights focus using the lenses, which means there is less of a need for reflectors like HID lights, which disperse the light without focusing and, therefore, need an external means of focusing.Full spectrum LED grow light provides plants in all stages from veg to flower with everything they need in the natural sunlight.Slim design that is foldable up to 180 degrees, making it small, compact, and easy to install.6 passively cooled bars provide broad-coverage lighting for full-term growth.Reliably sourced components including inventronics drivers.ECO Farm ECOM 1000W LM561C LED Grow Light BarsDesigned with Samsung LM561C chip, higher light intensity, less light decay , better lumens and PAR values than ordinary leds.Black Dog LED PhytoMAX-2 800The Black Dog LED PhytoMAX-2 800 will replace more than a 1000 watt HPS with higher yields and better quality results while using less electricity.The PhytoMAX-2 800 utilizes 420 Top-Bin 5W LEDs from industry leaders such as Cree and Osram, rated at 50,000 hours.

The LED grow light industry has gotten to a point where it can finally deliver the same quality to the small scale grower as it can to large commercial operations.Most importantly, it can do so without breaking the bank.As many will recall, it wasn't all that long ago that small to medium to sized growers were priced out of quality LED lighting options.Unless you had bottomless pockets, you couldn't afford to shop for LED grow fixtures.It's not the case today, with a recent series of high powered LED lighting options targeting the small-time operation.Here we will compare two notable options on the market today:Growers Choice ROI E-680Fluence SPYDRx PLUSGROWER'S CHOICE ROI-E720For the home hobbyist or small scale craft cultivator, there are a few notable LED grow options now.With unbeatable safety, reliability, savings and performance, the ROI-E720 is unquestionably the right choice for cultivators who demand only the best.FLUENCE SPYDR 2IThe SPYDR 2i 40" provides excellent coverage over a 4' x 3.5' canopy.Tailored for growing plants from initiation to senescence (germination, clones/cuttings, mothers, vegetative and flowering applications) in indoor environments.
However, it also means that it’s not always clear what the best alternatives are, especially when new tech comes out so fast.When you make the decision to invest in your indoor grow, you'll definitely want to learn about the best LED grow lights.LEDs are regarded as some of the best indoor grow lights on the market, but there are so many out there that it can be tough to weed out the cheap, unreliable brands and models from the legitimate ones.And with the price of some of these grow lights, it's crucial that you do your research before purchasing.Before you buy an LED, you should make sure its the right light for your grow.What makes the best LED grow light?The best LED grow lights have a few things in common - a uniform spectrum, efficiency, high-power, and reliability/durability.Spectrum/uniformityThe best LED grow lights have a uniform spectrum, so if you have 4 plants under your light, they all get the same spectrum.We already touched on spectrum a bit, but its important to reiterate that the best spectrum consists of not just red and blue light, but also infrared (IR) and Ultraviolet (UV).Full spectrum LED grow light allow you to grow from seed to harvest with the same light, as opposed to having to replace bulbs or use different grow lights for veg/flower.PowerThe more light your LED actually gives off, the bigger yields you’ll get (for the most part).This Mars Hydro FC 3000 fixture is ideal for a seedling to harvest grow in a grow tent or in a grow room.Use as primary lighting.Ultraviolet and infrared light bulbs are incorporated alongside the Epistar SMD chips to create the full spectrum sunlight-like light output.The quantum light board is covered by glue for water resistance.No veg or bloom switch, the sunlight spectrum is suitable for growing cannabis from seed until harvest.Yearld Pro 330W LED Grow LightThe yearld Pro 330W Grow Bar uses top of the range Samsung LM301B full spectrum LEDs, perfect for veg and flowering stages.
It is a messy affair but still functional.Things to Consider When Buying a Rosin PressThere are three important elements (other than the weed itself) involved in making rosin: heat, pressure, and time.And whatever you do, try to only focus on rosin presses with a yield of 20% or more.A cheap rosin press might save you money initially, but what’s the point if you’re yielding just 10%?Heat Plate QualityHeat is a crucial element in rosin production, which is why you should always consider the quality of a machine’s rosin press plates.Most machines come with square plates, but narrower, rectangular rosin press heat plates lead to better yields and terpene profiles.Best Rosin Press to Buy 2020Simply listing one model as the best is impossible, given the large variety of types, each of which is designed to fulfill a different role.That recommendation represents the best value for money.We also add a few alternatives for those who need something more powerful or those who are on more of a budget.
There are even a couple of quality presses under $500.But with so many options, choosing the right one becomes much harder.First you need to weed out all the low quality models.Then you need to determine which of the remaining presses is the right one for you.It can seem overwhelming and that's why I'm writing this guide.Before we get started, a summary of our recommendations and a brief note on pressure.WHAT ACTUALLY IS A ROSIN PRESS?Rosin presses are used to produce solvent-free cannabis concentrate and they require just two things to work correctly: heat and pressure.A rosin press uses a solvent-less technique to create cannabis rosin, and this will eliminate any solvent contamination of the cannabis end-product.A rosin press also removes the need for the dab enthusiast to clean the machine of solvent impurities.There are lots of rosin presses on the market, but before purchasing the best one for your needs, it’s good to know as much as possible about a rosin press’ benefits and features in order to be able to make the best decision for your specific needs and preferences.Rosin Presses have risen to popularity in lieu of more and more people waking up to the real benefits of CBD, and there are those out there who want to push the envelope even further to extract their own.This is just one of the many uses of this kind of heat press, but generally in 2020 the method of CBD extraction is what you find users wanting their own machine for.SELECTION OF THE BEST ROSIN PRESSES IN 2020Below you’ll find a comprehensive guide to what we consider to the best rosin press machines you’ll be able to find this year.We’ve taken into consideration all of the different uses you may need a press for, focusing on the size and press of presses to find ones that are portable, within a reasonable price range and ultimately can deliver a variety of pressing features that will be of use.The size is kept compact, making it more suitable than table top units for rosin production at home or on the go.This causes the rosin and wide variety of terpenes to exit the plates to a cool, safe zone immediately.Each terpene melts at a different temperature and will be pushed out one at a time outside the plates, this allows for the highest-quality rosin and maximum yield with only one press!
Rosin has been around for a few years now and is increasingly becoming the go-to for many cannabis extract lovers.Some “artisanal” attempts at producing rosin include using a hair iron or clothing iron, which is certainly not recommended if you don’t want to end up wasting that “good stuff.”Picking a best rosin press machine can be an even bigger challenge than producing rosin altogether.The press you go with will ultimately depend on your production volume goals and the raw material you’ll be extracting the concentrate from (flower, kief, or hash).Which are not always evident until you start experimenting with the process and final product.What is the Best Rosin Press on The Market?When it comes to finally decide which rosin press you need, there are many considerations to take into account.It also helps to avoid burning yourself!ECO FARM High Pressure Portable Rosin Tech Heat Press 2019 Prime 2 Ton Manual Heat Rosin Press.You can dial your heat for each plate to the exact number you want.
Whether starting with a single grow tent, a stealth grow box, or a full scale commercial marijuana grow room, how you set up your growing space goes a long way in determining your final yields.Growing indoors will provide you the power to influence all necessary inputs for growing big, healthy, cannabis plants with those big, sticky buds you dream of.Instead of being dependent on weather and soil you can optimize your production for maximum yield.The 3 Most Common Types of Modern Grow LightsCFL bulbs tend to be used in smaller grow tents due to the fact that they don’t heat up too much, so all you need is a reflector with a socket, pulleys and the bulb to complete your installation.HID or high-intensity discharge lamps have been the grow lights of choice for every kind of indoor grower from beginners to pro cultivators since the early 1990’s at least.The latest generation of LED systems are now capable of producing comparable, and in some cases, superior quality marijuana than the average HID set-up.PAR or photosynthetically active radiation is the metric that LED zealots consider most important.It’s best not to get too obsessed about the various new measures of indoor grow light and modified light spectrums.Think of light in terms of watts and electricity bills.
What are the Different Types of Grow Lights?There are three different categories of grow lights that you need to know about:Fluorescent Grow LightsHID Grow LightsLED Grow LightsFluorescentLike its name, a fluorescent bulb or tube uses fluorescent to give visible light.As the electric current moves, the mercury inside the bulb take up energy and produce a short-wave light that causes a phosphor coating inside of the lamp to glow.Fluorescent lights come in many form factors, including long, thin bulbs as well as smaller spiral shaped bulbs (compact fluorescent lights).However, LEDs soon prove its worth by performing efficiently and displaying some discernible unique advantages that other grow light types cannot have.Led grow lights are in popular use nowadays either by hobby growers and commercial greenhouse farm.But 50 watts each square foot is optimal.Now, calculate the lighting needed for the area you grow.)Utilizing this technique also offers a grower the advantage of keeping smaller plants out of the shadows of the larger ones, an issue which would compound the lack of light.
