I added a second 200 watt in my 4x4 one is an HLG 200rspec and just put in a viparapectra 200....how high should they be and what intensity would you say for all stages of growth seedling/veg/flower....adding the second light confuses me as to how the light will hit now....have to grab a ppfd meter in the future.........I think I have them about 24" right now at 75% my plants are vegging
I've seen the charts for both lights for ppfd just now sure if I follow that or raise them or dim now because there is a second light in there.
for veg that is fine but flower you need to lower them both and crank them up for example i am running 2 600 true watt hps at 110% 14 inches away and have not burned my plants so you can get as low as you want
I moved them up to 36" on 75 percent and they are now praying again....wondering if it's not the new height of the lights but the timing with someone else that made them start praying again...they were cupping and curling downward a couple days ago and as soon as I moved the lights up they seemed to get better...not sure if its the ocean forest and too much nitrogen but I really want to know if 24" at 75 is too close for early veg
