Start at 36"inches and work your way to 18" as the plant grows.

How many plants in a 70x70x160cm tent with 100W?Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

LED distance to plant adviceInterested in how close I can get my 630w LED with a rating of 2.7μmol/W and 1700 PPF to my canopy. I had it hung 48cm (19 inches) on 380w and just upped it to 500w day 8 in flower. Does this sound too close at 500w or is this ok? Temp is 25C (77F) humidity 55%.

Bloom Light SupplementI am a one plant windowsill grower, but having trouble getting enough light for bloom due to cloudy days. I have a three prong red/Blue LED light off Amazon, Wakyme, that is not cutting it. Would this lamp work? Two bulbs. I will have to suspend it from a clothes rack.

Light spectrum during veg and bloom periodsI have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?Setup. Lighting

ViparSpectra P600 or P1000?I'm just starting with a small setup (40x40x100cm tent), only one small plant at the time, but want to be able to grow proper quality in long-term. I suppose the biggest difference between the two lights is the 930 vs 1006 umol/m2/s? Any advise appreciated!Setup. Lighting

Seeking a reasonably priced light for 2x4x6 tent (still)I'm interested in picking this up. Thoughts? I have a 2x4x6 tent. I believe it's 50w x 8sqft is 400 watts needed?
