Heyho So apparently my plant got bigger than I thought. After stretching its only 30 cm from the Mars TS 1000 (Its already on the highest possible position) And I'm running it at ~80% Do you think I can turn it up to 100%? It's always nice to go here Thanks for helping H. G.

Light height full power vs dimmed
Hi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)

Help, they start to taco.
I think its to bright and to hot, seeing some taco leaves. Sanlight on 100% for few days, temps go up to 32C Next plan is to add BB Grow,Bloom,CalMag,TopMax,BioHeaven,Activera,Algamic no Canna Mono Mag anymore. What do you guys say to feed? Light back to 80%? https://growdiaries

SF-1000 safe distance and dimmer for seedlings in soil?
my seedlings are stretching and not growing in size. soil, autos, dropped in water 7 days ago and moved to soil in solo cups. What are people running the SF-1000 at for seedlings? I was at 30" and 20% but that's not good clearly. I've moved to 24" @ 45% so far.

Too much light ?
So started my second run and got everything dialed in but this time I’m running with spf-1000D and the normal spf-1000 is that too much light for the plants that would slow them down ? Together the lights should be around 200w

What’s the ideal amount of LED light for top quality in a 4x4 tent.
I’m exclusively looking to grow top end quality. Already can with HPS setup but wanting to switch. Is 480w Kingbrite LED quantum board with 385,660,730nm enough for this or do I need more? Any other suggestions? Aliexpress/Alibaba manufacturers preferred due to shipping costs.

Mars Hydro TS1000 hanging height
People with experience using the MH TS1000, between 24"-30" at 25% seems like a reasonable height to put my light over the plants in initial vegetative state at my 2x2ft tent? Thank you! :)

Is it too late for scrog and have I had the light too low during the veg stage?
So I noticed pistils appearing and now I'm worried that I've had my light too low during veg (~8k lux). Is it too late for scrog at this point or will they continue to grow? I've now bumped the light up to 22K lux should I lower the light to increase the intensity even more? TIA
