Yea, 14" would be about the same as me. I don’t top them. I’ve been flopping/supercropping them, like what @Mr.Sparkle does in his microgrows.
I actually think the plants like the smaller pots more, down to a certain size. It promotes more wet/dry cycles, which gives them more air.
My watering schedule goes something like –
Transplant to 1 gal pots after 2ish weeks in small pots, feed once every 2-3 days at first.
After about a week of that, feed about every day.
Change lights to 12/12 flower.
After about a week of 1x per day, increase to 2x per day.
Another week after that, increase to 3x per day.
You still gotta start them off slow and work up to 3x per day, but it goes pretty quickly. I just pick up the pots every couple days just before lights off, and check if they’re getting really light yet. If they’re feeling pretty dry, you can increase the number of feeds.
All that “can’t overwater coco” talk is total bullshit. Don’t believe anyone who says that. Maybe it won’t kill your plants, but they won’t be happy.
