When to put the light on?
Panzora
started grow question 4y ago
Hey there, Do you need to put the light on the pots directly after you planted the seeds in the ground? Or do you need to wait untill they poke true the ground and then put the light on them?

Plant can't absorb light till leaves open. But I leave the lights on anyway because I don't mind paying my electricity bill.

Light distance and when to top?
I'm using a 300W LED. What distance should I keep the lights at now that I've transplanted and the plants are doing well? I'm thinking 24" and then move up as they grow until flipping. Also, when should I top? I've read that waiting for 6-8 nodes is the right way to go.

When to flip into flower?
currently midway through my 9th week of veg and am wondering when I should send plants into flower, should I double check sex first? (Feminized seeds) or wait until my screen fills out more? Plants are in 3 gallons pots and I worry that they might get rootbound if I veg Longer.

dli 40x40 growbox lamp distance problem
hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?

Autoflower light schedule
Soon rolling into veg for my first auto grow. Currently on an 18/6 light schedule using Mars Hyrdo II 700w . Don’t have any problems with temp/humidity inside tent. Once you notice the buds starting to flower do you switch to 12/12 or just keep plugging away with 18/6?
