first time growing weed plants

When designing your space, you’ll need to take into account room for your plants, as well as space for lights, fans, ducting, and other equipment. You’ll also need space to work on the plants. Cannabis plants can double in size in the early stages of flowering, so make sure you have adequate head space!

Multiple harvests

Remember, a common mistake newbie growers make is to overwater plants.

Watering and nutrients

Without proper airflow, a grow space can experience rapid changes in humidity or develop pockets of CO2 depletion, neither of which are good for plant growth. CO2 depletion can lead to nutrient lockout, and areas of high humidity are prone to pest infestation, mold, or mildew.

Russet mites are microscopic, but visible with a 100x pocket microscope. The reason they are so feared among growers is that by the time damage becomes visible, the crop is often irrecoverable. That is why it’s important to do preventative pest control and maintain constant vigilance. Don’t wait till your plants look sick! Russet mites look like tiny milky colored maggots with four legs in front. They are much harder to spot at first and, unlike spider mites, are literally microscopic and can only be seen with a 100x pocket microscope. Growers are still struggling with organic control methods. Natural insecticides based on essential oils, neem and yeast enzymes all seem to work to varying degrees. Check with your local grow shop. We recommend doing routine preventative control even if you don’t see russet mites with your microscope. The good news is that anything you do to control russets will also control spider mites, thrips, fungus gnats and most other cannabis pests.

Growing any plants indoors under artificial lighting, but especially cannabis, requires some research, skill and practice. There are many books and websites dedicated to it.

Spacing
When provided proper care and large root space, outdoor, seed-grown plants can easily grow to be eight feet tall and equally broad. In some cases they can grow twice that size, all in one short season. Even for a beginning gardener, a well-cared for cannabis plant in a 20-gallon pot can still get four feet tall by equally wide, so plan your space accordingly.

Detailed pest control is beyond the scope of this page, but you’ll need a small hand-pump sprayer and some organic pesticide. Any good grow shop can advise you. You don’t need to spend a ton of money to do basic preventative control. At the nursery, we use various organic pest control sprays preventatively about twice/week, but most home growers won’t need near that often of a spray schedule. If you are diligent with your microscope inspections, you may not need to do much at all if you don’t see any mites.

First, some basics about cannabis plants.
Cannabis is a “genus”, a taxonomic unit used by biologists to classify living organisms, that contains several species: Cannabis indica, Cannabis sativa and Cannabis ruderalis. These interbreed freely, resulting in “hybrid” species that contain features of both parent species. (Note that Cannabis nomenclature is changing. Stay tuned.)

Cultivation Basics
Cannabis is as easy to grow in your garden as a tomato plant, but there are some rules of thumb that will dramatically improve your yield and quality.

Brown/gray mold, also called “bud mold” or “stem mold” is a systemic fungus that rots buds from the inside out. The best way to prevent it is to keep the plants from getting rained on during flowering phase and to provide extensive dry airflow. Once mold is identified in a bud, remove and discard the infested part and harvest the adjacent bud to limit the spread.

But, with clones there’s a catch. Clones are cut off of a mother plant that is kept indoors under artificial light for 18 hours or more per day, so the mother plant and the little cutting “think” they’re living in an endless summer of long days and therefore remain in vegetative phase. If you put that rooted cutting outside in the spring under natural daylight, when the days are short, it thinks it’s fall and time to flower. A seedling, on the other hand, will wait till the light naturally fades again in the fall to go into flower.

The process of identifying which plants are male and which are female is known as “sexing”. It is an important part of cannabis cultivation that takes an experienced eye. At the nursery, we take the guesswork out of it and guarantee that our plants are all female.
