For best results, make sure the buds are directly exposed to light. Most experts agree that you need to use HPS lamps when growing marijuana indoors. Remember, your plants need 16-20 hours of light during the vegetative stage. Switch to 12 hours light and 12 hours of total darkness in the flowering stage.
If the pH of the soil is below 5.8, your plant won’t absorb magnesium. This becomes apparent when your cannabis’ leaves begin to turn yellow. If you are using a non-soil growing medium such as Rockwool, keep its pH at around 5.5. There are various products available online to either increase or reduce soil pH levels.
Marijuana plants, just like every other plant, need nutrients and timing is everything. During the vegetative stage, use nutrients with a high level of nitrogen, phosphorus, and potassium (N, P, and K). A ratio of 3:1:2 of NPK is ideal.
3 – Temperature & Humidity Settings
You can invest in a CO2 generator if you are growing lots of cannabis plants. Be careful, though, as excessive CO2 levels are harmful to humans.
You won’t get healthy buds unless your plants are exposed to their preferred temperature and humidity levels. These levels vary during the different stages of a marijuana plant’s growth cycle:
2 – Achieving the Perfect pH
The sheer array of equipment available to cannabis growers means it should, in theory, be easy to produce a bountiful harvest. New technology means you can grow dozens of plants in a small area, assuming you have a commercial license. Otherwise, you need to get the most out of a handful of plants, or the time you invest will amount to very little.
After years of trial and error, it has been determined that you need 400 Watts of light during the vegetative stage and 600 Watts during the flowering stage for every 13 square feet of growth. If you’re concerned about the energy cost, purchase fluorescent lighting to save money.

Female: Two pistils (the pistil contains the reproductive parts of a flower) will be growing on the buds (flowers grow above these leaves, one cluster on each side).
Cannabis growth is made up of a series of stages that plants undergo during their lifecycle. Each stage during the cannabis cultivation process requires its own unique demands, including different levels of light, water, and nutrients.
The quality of your plant depends on your knowledge of the cannabis growth stages and the lifecycle of your plants.
