started grow question 4y ago
Looking to upgrade my maxibright daylight pro 8 bar led light to something a bit bigger and beefier. Something that has a span of 1.5m x 1.5m and ideally more power. 1000w etc. Any suggestions on what works well and why you like it? Thank you

And if it's not difficult, tell me how I should control the light at all stages of growth from growth to the end of flowering!? at what distance from the plants should the light be? and what power adjustments on the driver should I make?

Led mounted on side wall instead of top
So I'm thinking about to build a pc grow box, just for seedlings. When they start to be bigger I'll move them to bigger grow box. I have a spare grow light but it's to wide to mount in top of grow box. So I was wondering if I could mount it on the side wall?

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

Seedlings struggling
This is day 10 since they popped out and it just seems as if my seedlings are stunted. I kept an 85w CFL about 10cm from their tops for the first week and then raised it up to about 15cm for the next few days. They had humidity domes. Temp was 20°C-24 in day

Led on 18/6 grow/flower photoperiod
I have the idea to put a led in my second tent for pre growing photoperiod girls, I have some room left over for some autoflowers who also grow & flower on 18/6 light - leds can switch between grow/flower. If I switch the led to flower will that be OK for my photoperiod girls?

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.
