There are also cannabis plants that aren’t light-sensitive, called autoflower varieties, that will automatically flower on their own at a particular point of their maturity independent of how much light they’re getting. These plants tend to have much shorter life cycles, which is appealing to some gardeners.
If you aren’t working with exclusively female plants, you’ll need to get rid of the males before they have a chance to pollinate the females (and wreck your harvest). “Even feminized seeds can have up to 10% males in the mix so it’s important to inspect your plants every day as they start to show their sex. Also important to note is that a stressed female plant can produce male branches or ‘hermaphrodites’, so even if you know she’s a girl, you have to check daily,” advised Sara Rotman, a veteran grower and founder of Wellfounded Botanicals.
Phases of growth and timing for outdoor growers
Use a grow journal. Tracking the details of your grow efforts, from germination to final cure, will help you become a better cannabis-plant parent. When it’s time for a new season, reviewing the successes and failures from the last crop will make your thumb greener — not to mention improve the quality and quantity of your final harvest. There are lots of ready-made cannabis grow journals out there, but really all you need is a pad of paper and an eye for detail.
If you’re growing from seed, the first step in the life of your cannabis plant is germination. Once the seed has sprouted, it will immediately grow two little round leaves, called cotyledon leaves, that will be responsible for delivering energy to the seedling until it starts to grow the more familiar fan leaves we all know and love.
