What light spectrums are best for early stages of ...
motaman311answered grow question 7y ago
You want to have both spectrums. The ratio is more strain dependent, but red light should be used in conjunction with blue light to increase photosynthesis and plant size. Here is a good youtube video where he does an experiment using blue and red lights. Good luck and happy growing! 👊 www.youtube.com/watch

Dual spectrum all the way. More reds can be added when flowering but don't take away the blues

Blues for veg and reds for flower. Full spectrum leds seems to be doing very well for all stages of cannabis growth

Removing big fan leavesLast night I began removing the lower big fan leaves, but only the ones that are over 75% yellow and brown, and leaving all that are green. I saw more growth this morning so I think I'm fine so far. Should I remove the big green fan leaves or wait till they turn yellow?Week 13

Referring to the last 4 photos: I think I could have removed many more leaves, but I wanted to ask you if I should or not.
Referring in particular to the last two photos: what should I do with these little stems for a proper defoliation/lollipopping? Leave them or chop them off?Week 8

Ive noticed that during winter I only need to water the plants once a week or so.
Is that OK for a SpaceBucket with a ufo led?
What's better? several small waterings or a big one once a week?
Im using 1,25L a week, should I try to break that quantity to 2 waterings?Week 9

As I'm increasing my P/K boost levels each watering, I'm ending up with lower and lower pH. I've heard it's not recommended to add silica during flowering, such as that found in GHE pH Up. Is that true or not really a big deal? If true, are there any good simple alternatives?Week 12
