Make sure your trellis is strong. An A-frame trellis works well with heavy vines, giving sturdier support than an upright trellis or bamboo teepee. The vines have clasping tendrils that will grab hold of any type of thin support such as netting, bamboo, or twine.

Paul – Plants grow upwards because they’re trying to get to the light to begin photosynthesis, but mostly germinate underground where there’s little light to follow. So, they sink due to gravity and it’s this movement that allows the plant to tell which way gravity is acting.

Each part of the plant has a different reaction to gravity, roots grow downwards (positive gravitropism) and shoots grow upwards (negative gravitropism) to search for light.

The topic we will be looking at is the human egg, which is the female seed. Reproductive cells, or gametes, have half of the genetic information required to form a new individual; thus, the meeting of a sperm with an egg results in a full set of chromosomes.

Any seeds wil be female and if the environmental stresses are corrected the seeds will flower like any other seed. While those growing for profit or meds may toss “hermie” seeds for connivence many MANY others grow them out with great results. Some of the most best well known strains started with “hermie” bagseed.

Feminized seeds produce only female plants, and when they germinate there will be few males among them if they are produced correctly. Feminized seeds are produced by inducing a normal female, not a hermaphrodite, to grow male flowers with viable pollen.

Feminized seeds occur as a result of inducing a female plant to herm, then fertilizing another female plant with the pollen. The pollen from the ‘hermie’ contains only female chromosomes, so that no true males can result from the seed.

Heat and Light stress are the two most common causes of a marijuana plant turning into a hermie. Don’t leave your plants gasping, but don’t drown them either. Do all your staking and pruning and plant training during the stretch period and keep a light hand. As soon as flowering starts, leave well alone.

But for good measure, here are two ways you can pollinate a self-fertile plant: Carefully shake the plant or blow on its flowers to stimulate pollen release; or. Gently swab the inside of each flower with a small paintbrush or cotton swab to transfer pollen into the pistil (middle part of the flower).

Out in the open, pollen may be viable for one or two weeks under normal conditions. However, when frozen and sealed, it can last up to a year and even longer. Pollen is more unstable than seed and even under the most optimal conditions, it isn’t expected to have as long of a shelf life.

If you find seeds in your harvested buds and there is not any male plant near your growing spot, it is because there was at least one hermaphrodite plant in your crop. Those male flowers that were not removed released their pollen next to the female plants.

No. Household bleach like Clorox is dilute enough that it generally causes a bellyache and vomiting at worst. Some industrial-strength bleaches will certainly kill you, but the method is grisly: it’s caustic and burns the esophagus.

Wash everything you work with in hot, soapy water; rinse completely; and be sure they are thoroughly dry before you use them. Clean all of your tools with isopropyl alcohol to disinfect them. Residual organic matter in soil can be a host to diseases and fungi, so it’s best to start each grow with a sterile mix.

Below are some basic best practices to incorporate into your operation to reduce contaminants and mold growth:

1. Isolate dirty tasks.
2. Compartmentalize the grow space.
3. No drinks or food allowed.
4. Empty all trash daily.
5. Axe the brooms.
6. No standing water or high humidity.
7. Require coveralls for all employees.

Citric acid, soap and isopropyl alcohol eliminate mold spores and harmful bacteria. You should also spray it directly on the surface of the soil to mitigate mold growth and kill any soft bodied insects hanging out there. This product can be sprayed directly on the grow tent surfaces – as well as on your plants.

First, try hydrogen peroxide as a soil drench to kill gnats and larvae. This will kill any microbial life in your soil, which is not ideal, but better than your plants dying from an infestation. Once your infestation is under control, reintroduce these beneficial microbes with a compost tea mix.
