my theory and i am still a newbie 4th grow now is as soon as the leaves get as big as my hand i flip to flower not all the leaves just 1 or 2
What strain you running? Saw your other posts- plants looked great!
I’m on my 5th grow, but just started last year at start of PanD. RIU has been great info, if you cross-reference it. Not that I haven’t been mavericking (flashy way of saying possibly reckless experimentation, haha) on some of my plants. But all with love.
Anyhoo- the one I vegged for a long time was a GG4 clone from a friend, and the first I put in ground. Called her spot The Lantern because it was in a 1.5ftx1.5ft. bed outside that I sided with corrugated plastic, and had thick bamboo poles coming from the corners holding a glass pane and plastic roof that held a clamp-on type light on a timer to give her 18hr. “days”. She was probably 3-4 weeks old when I got her around late March. Lasted into fall but would have to look back to see when exactly. Ran successful other grows of same clones simultaneously and made a few and ran them or gave away. Flipped some in closet then transferred outside and tented from 8pm to 8-9amish (was drinking a lot back then- not as early a riser then). Those did great in summer sun and had a way better harvest by flipping them at a healthy, branchy, leafy stage. I miss that clones phenotypes!
rambling, sorry...
Popped a seed I randomly found last year and it grew into a monster, au naturale, with leaves that I measured at 11 inches! Did great outdoors and had zero pests and high botrytis resistance. Tried to clone too late and wasn’t very good at it (rockwool doesn’t work well for me?); she was the one that got away I will never forget. Very fruity, smooth smoke, with happy relaxed high.
