Hi guys i am a learner from the uk and these are my mexican sativa potted 4 weeks ago they are outdoors in a pvc green house growing by the day do i start to super crop and do they go on a 12 hour cycle yet any advice would be grateful 😊 thank you
I'd let them get a bit bigger before you super crop them.
And go 12-12when you think the plant is big enough.
Depends on size of your green house
They are abit small to start flowering all ready. But they are looking nice an healthy.keep it up
