best seeds for growing weed indoors

Indoor growing also allows cultivators to take control of time (to a degree, at least). Photoperiod cannabis varieties begin to flower only when the hours of light decrease leading up to autumn. Indoors, growers can change the light cycle to trigger flowering whenever they want. Alternatively, they can extend the growth phase by keeping plants under a veg-specific light cycle.

Indoor growing makes life easier for many cannabis cultivators. If you live in a cold climate with bad weather, or your garden lacks direct sunlight, indoor grow tents provide a safe haven. The ability to manipulate the light schedule, humidity, and nutrients with precision allows growers to raise weed on their own terms.
