answered grow question 5y ago
At this stage, I would go with 24 to 30 inches, as they grow you'll be able to bring the light down to 18 inches.

Doubling light/adding a panel in flower
Adding a second light panel-- any tips? Will it be too much? I've been using a viparspectra p1000 in my 2x3ish closet and it's done me well up to this point. Today I've installed a second led panel (not as good as vipar). Wondered if it'll be too much?

Nanners?
Can someone verify my latest 2 photos look like nanners? If so, I’d love some insight on why my plants seem to be so light sensitive. Most growers seem to blast their plants with upwards of 200w with little issue. Mine is sitting at 80w 22inches and it seems to be struggling!

Growing out instead of up.
Please help out! I moved it into a new pot and topped it last week as suggested. Also new ViparSpectra light at 45cm away @80% power. Nutrients/food yet to arrive. It seems to just be growing out instead of up, and starting to see some white/ burnt looking spots. Suggestions?

HPS 400w Vs MarsHydro TSW2000 cost
Alguém me sabe dizer o quanto menos uma luz LED gasta comparado a uma HPS ? Por exemplo, estou usando uma HPS 400w, e subiu 40€ na conta de eletricidade, se usar uma MarsHydro TSW2000, iria fazer grande diferença ? Obrigado

Woke up this morning and she’s grown a bit from yesterday. 4cm tall now. HLG 135 was dimmed (to a level that was comfortable to look at, I have no way of measuring output right now) and is 26” away. I know it’s early but I have no experience!

Which light
So I’m a new grower and I have the mars ts600 for flower and veg but I’m looking at getting some more power when in flower. I dunno whether to get another of the same light which is 100w or go for the mars ts1000 with is 150w but with both ts600 I would be pulling 200w together

I have several question about my setup for the first week:
- is the distance of the light to the plant ok? - is the intensity of 25% correct? - should I remove the seed coat or should I just let Mother Nature do it, eventually it will be blown up..
