The plants look still very short. I would like to get them little bit taller. I use hydrofarm reflector, so i kerp the light close to plants(30cm) How far away should i move the light? 60cm for one week?
Hello ! Hid 400w is good at 40cm (from the top of the plants) without cooltube and 20 cm with coultube so 30cm or 20cm could be good in your case. If you just want to make your plants stretch then put the light higher like you said 60cm could be good but they will only get taller without real beneficts as the space between the nodes will be hudge and you could loose light penetration to the lower buds. I hope it will help you :grin::+1:
I've seen a few of the seed companies defoliate at the start of the final two weeks.
This to allow as much lights on the buds in the final bulking up phase.
Personally I wouldn't defoliate anything servicing primo bud sites and stick to leaf tucking whenever possible.
Those big healthy fan leaves, they are the ones that really fuel that meristem/node and its flowers.
Concerning light distance ... I always thought you have to end at Wattage/10 cm for HID. So 60 cm tops - at the end of bloom - for
a 600W HID.
