So, you are keen to grow marijuana seeds at home? Great idea! Buying online with no proper knowledge can mislead you into buying mixed (male + female) seeds.

Yes, marijuana seeds are gender biased. They have a male variant that yields no buds while female plants generate buds. So, which one is better? Definitely, the female which has a much higher concentration of THC. All feminized seeds would mean 100% production result as all plants will bear smokable buds. These female seeds, aptly called feminized seeds, are created by breeding two female plants. You can cultivate these seeds at home by following this DIY guide.

The process of feminizing seeds forces the female plant to produce pollen sacs like a male plant normally would. These plants can then pollinate other females. Genetically, they can then only produce female seeds.

How to Create Feminize Cannabis Seeds

Step 1: Light change: 12 sunlight/12 darkness.

Take one female marijuana plant and change its course of light to 12 hours daylight and 12 hours darkness each day until its flowering stage. If you’ve made it this far, you likely have a quality grow environment whether a tent or other.

Step 2: Role change: Force a female plant to produce sacs

This can be done in 3 following ways:
A. Naturally by Rhodelization – Low yield result
When a female plant under stress tries to survive in the wild, it naturally starts producing pollens to save its next generation. However, this makes the plant turn into a hermaphrodite ( a plant that produces both male and female flowers). Thus, upon breeding it is likely to produce hermaphrodite seeds. Therefore, we do not recommend this method!

B. Silver Thiosulfate method - Best yield result
This chemical commonly referred to as STS is the most efficient method. STS is a mix of half sodium thiosulfate and half silver nitrate that causes a hormonal reaction in the plants. It keeps the female hormone under presser. Thus, When you spray STS on female plants they naturally start producing pollen sacs. However, it does not become a hermaphrodite plant, unlike the above case. Simply spray your female plant, allow it to dry, and place it among its friends.
In this process, your plants have some risk of becoming hermaphrodites. Try to avoid this as much as possible by observing your plant and breeding out plant lines with sex changing tendencies.

C. Chemically from Colloidal Silver - High yield result
Colloidal silver is much easier to find and is the most popular method because of its high yields. Like before, the stress enhances production of the male hormone.

How can you get colloidal silver?
Buy ready to use colloidal silver – This is best only when you need a few seeds. A large quantity seeds would turn this project quite expensive for your pocket. Note: A ready-made solution of anything above 25 PPM (parts per million) silver would be ideal.
Buy a colloidal silver generator kit – This is economical as you can produce colloidal silver as many times as you please, for as much quantity.

As the plant reaches its flowering stage, start spraying this colloidal silver on the plant buds (the junction where the leaves meet the stem). Spray it daily until the flower starts developing pollen sacs which will later burst into pollen grains. Stop spraying once enough pollen sac become huge and fluffy, usually after 4 weeks.
Caution! Please use the mother plant only for pollinating to testing. Do not smoke with it because colloidal silver is harmful to your health. If you happen to use the pollen flower by mistake, seek medical care immediately.

Step 3 Harvest: Store pollens

Pollen sacs are ready for harvest when they are full and just start to open. If you stop spraying too early, the sacs might be empty. Once the pollen sacs are ready, harvest them, and keep them in a cool, dry place for about a week. Now, put these pollen sacs in a Ziploc bag, shake them and tada! The pollen grains have busted from the sac. In case it doesn’t, you can always cut and remove them. These pollens can be stored for up to a year if you manage to keep them away from the moisture! Add baking flour every once in a while to keep them dry.

Step 4: Pollination: Feminized pollen with Feminine flowers
Now pollinate 3-week-old female flowers with the feminized pollen grains using a paint brush. We do not recommend fertilizing the mother plant that produced the pollen since genetic diversity breeds stronger crops.

Step 5 Seeds: Use or Store

After about 5-6 weeks the flowers should start producing seeds. Make sure you don’t wait until the seeds start dropping. Be aware that some plants might begin to die just as the seeds become ready for harvest. Collect the viable seeds. It is up to you if you want to use it or label and store it.Knowing what we do about female marijuana plants, why even have male plants? With the feminization process, we limit genetic diversity which can sometimes lead to fragile or genetically diseased stock. Male plants cross pollinate and keep your crops sturdier.

Feminizing seeds is a lengthy process, and it often requires a lot of practice. In general, growers make several attempts before their first successful feminization. For most personal growers, the process requires too much time and money to not guarantee results. For professional growers, the process makes much more sense. Once they have their custom stock, cloning ensures the marijuana maintains its consistency. Not to mention, feminizing is much more cost-effective in bulk. Nonetheless, hobby growers find great joy in feminizing their own seeds as a feat of personal accomplishment.

If you're looking to increase your yields via the addition of carbon dioxide, the best way to integrate into your grow tent includes a variety of proven strategies.

Let's start first with the easy and most cost efficient, CO2 tanks. You can buy a 20 lb tank that will last you a few cycles for only ~$150. Some growers swear by co2 tanks as the most cost efficient, and we recommend using it with a co2 controller/regulator.

Next, you can also try two other options. Dry Ice is our second most effective after CO2 tanks. Third comes CO2 bags, which are mycelial mass fungi that happen to emit CO2. Dry ice only lasts for a week or two, and same with CO2 bags. With CO2 bags you'll have to hang them all over your tent for any kind of significant effect.

On a different CO2 topic, if you're using CO2 and high pressure for your cannabis extractions, be sure to review the new and advanced method from ESCET LLC, cannabis extraction consultants and expert cannabis chemist Joseph Payack.

Often, when growing in a confined space and aiming to grow cannabis that has a low growth height (generally indica strains are shortest), then you will want to explore your low height grow tent options.

gorilla grow tent with adjustable heightExplore our Most Popular Low Height Grow Tents

Gorilla Grow Tents - The Gorilla Lite Line and others have relatively low heights compared to Lighthouse Tents, Apollo, and most other reputable brands we have reviewed. The Gorilla Lines come with 12-inch height extensions to increase height when needed or keep short for the more compact growing areas.

Keep in mind with small growing areas that your ventilation and heat may be a concern. Always think in worst case scenarios, you don't want to start a fire in your house and endanger yourself or someone else.

Yes, they do! It all depends on the quality of the led grow light. The quality, in or opinion, depends on a number of factors, including the type of individual led used, type of led light cooling, lumen output, wattage, and footprint size.

Let's begin by looking at deciding factors:

Type of Individual LED Used

The type of individual LED in the led grow light is extremely important to the strength and endurance of the total unit (unless you want to be constantly soldering and replacing led's) Light Emitting Diodes are made in different wattage, anywhere from 1 watt to 5 watt+ The lowest quality grow lights have the 1 watt LED's, and the best are now  3 or 5 watt LED's.

The brand of LED is also indicative of quality. CREE is widely known as the highest quality provider of LED's. Generally the low watt no-name brands from China are the ones to be careful of.

 

Type of LED Cooling/Ventilation/Structure

This generally refers to the thermal management/build quality of the unit, and the amount of care and engineering that went into the overall product. For example, the number one reason of LED lights failing is a lack of proper heat control. Heat control depends on the size and quality of heatsink, number and quality of fans, and organization of those items within the device. A good indicator of a grow light with a good cooling and ventilation is a long warranty. If the manufacturer is using parts that burn out, they can't offer a warranty without losing profit over time.

 

Power of the LED - Lumens, Par Value, and Footprint

Not only the actual wattage power, but the power of the light in lumens and what they refer to in the industry as Par Value. Par stands for "photosynthetically active radiation" and is measured in micromoles.  LED grow light companies strive to develop lights that emit targeted wavelengths within the PAR spectra to trigger increased plant growth response with decreased waste of energy. Light manufacturers are now adding more Red and Blue spectrum Par output for increased performance. Footprint or coverage refers to the area that the light will cover with sufficient output.

LED Grow Lights vs HPS

LED grow lights have a few important advantages over HPS grow lights. Let's start with cost. Although the HPS are a lower initial cost investment, over time you will save more money using LED's, due to the lower wattage and electricity usage. You may also save electricity by reducing Air Conditioning or Fan units in your grow room due to the lower temperature of LED lights. HPS lights run significantly hotter than LEDs, and with HID you will also have to replace the bulb after 3 or 4 seasons.

If you're looking to hide your hobby from the nosy neighbors, we can help. With proper pressure, ventilation, and tent, you can have a stealth smell proof grow that even hides the most pungent strains during flowering.

 

Let's start with the Best Grow Tent Pressure

Every grow tent should have negative pressure. This basically means your tent should have more air going out than coming in, creating a vacuum of sorts. A properly pressured and ventilated tent will have the fabric and doors etc suck in slightly, and be responsive to the touch. You don't want an insane amount of airflow venting out your main fan, we found on our 6 inch Ipower carbon filter with fan and adjustable knob we set regularly at only 1/3 of the power. Setting as low as possible setting on your carbon filter and main fan will not only save your electricity but also likely life of the fan and filter.

The Carbon filter itself is the main component of smell-proofing your cannabis grow tent.  They actually use 1050+ IAV Australia Virgin Charcoal to absorb the pollens, terpenes, and molecules that cause the distinctive scent of bud.

 

Next Let's Cover the Grow Tent Airflow

Getting the best grow tent airflow requires a nice setup of fans and vents. Not only do your need a good "scrubber", a.k.a. carbon filter (like the one mentioned above or others you can easily find on Amazon) with a fan that matches the ducting size (and size of the upper ducting hole of your tent), but you also need airflow via venting towards the bottom of your grow tent. This bottom network of fans and ventilation ducts works best with clip fans on your grow tent poles that circulate air coming in from one of your lower tent ducting outlets.

 

Extra Precautions to Remove the Smell of Growing Cannabis

We've known some extra paranoid or extra cautious growers who use extraordinary precautions with their grow tent smell. First off, we've all heard of putting in a circulating odor removing air filter house fan in the tent itself, and/or in the room outside the tent. Also, you may have heard of people using Ona odor removers, which we've tried with mixed results.

 

What grow tent is the most smell proof from our experience?

Hi fellow grow nerds! We're glad you are high enough to join us for this comprehensive article on grow tent fans.  Why are we writing this article? Because we see far too many incorrectly oriented grow tent fan setups, using unnecessarily expensive commercial or house fans, and/or not enough fan airflow.

The different types of grow tent fans include inline fans (which go inside your tent ducting system) Inline grow tent fans are the most efficient and effective way to properly regulate temperature and airflow in your tent. They can be attached right into the existing ducting, and/or installed as aftermarket equipment. The type, number, and power level of your fan should coincide with the ambient temperature of your tent environment, as well as the type of lighting your are using. The type of lighting matters significantly, as a LED grow light will need much less airflow to reduce temp than a metal halide or HPS grow light.
