I have a spider farmer sf1000 in a 31x31x71 tent. I planted 2 gorilla glue seeds on saturday and I was wondering about how far I should place it from the seedlings. Right now I have the light 25 inches away and set at 50 percent power. The seedlings look to be stretching a lot. Thanks for any help. These photos were taken this morning.

Just so you know those aren't stretchy bud. They look good. You can increase light intensity 3-5k lux every few days to a week. Just watch for light stress. I would give em 3-4 days before increasing. In a week they could probably handle 15k

Ok. They were under around 20k in the pictures. Now they are around 7k. Should I just leave them therw for a few days or put them back how they were to start with.

Just so you have some reference.

Clones 5K lux
seedlings 5-10K lux
Veg 18/6 15-45K lux
Flower 12/12 45-65K lux
Start at the low end of each for stages and work your way up 3-5K lux every few days

I never even thought about the droplets magnifying the light. They sure can though. I won't be doing that anymore. Lol
