Grow Q&A: When Do I Make My Pot Plants Start Flowering?

Dear Dan,
I was wondering when do you know when to switch to the 12/12 light cycle in my indoor garden? — Zach

Dear Zach,

The decision of when to induce flowering in your plants is entirely up to you. It’s important to determine how much space you have and to factor in the fact that your plants will stretch for at least a few weeks after flowering is induced. I usually recommend one week of vegetative time per each gallon of the container you’re using, so that a plant in a 5-gallon bucket should get approximately five weeks of veg time before the switch, while a pant in a-2 gallon container should get about two weeks.

Keep in mind that the longer you vegetate your plants, the larger they’ll be, but that also means more time for things to go wrong. Overwatering, overfeeding and pest issues have more of a chance to turn into bigger problems; also, your plants can easily become root-bound and end up not yielding as much.
