It all depends on the size of the plants! Maybe after the 3rd week of veg is when they really start needing more light!

Contemplating putting 2 plants outside. I have 8 in a 3x3 with Mars hydro tsw2000. It’s pretty tight in there. What do you guys think? Is 8 too many for the size and light? Or should I just leave them as is? I think the the pots are 3 possibly 5 gallon.

What would you say about my lighting based off the leaves of this auto? Too bright, too weak, or just fine?

Anyone else also use far red for emerson effect and get extra night hours really see a difference too? For sure they seem to be praying a lot harder after setting it up. They sure seem to be finishing faster.

Best Light Schedule for Autoflowers?
I'm wondering what light schedules my fellow growers like to use with their Autoflowers? I'm debating weather the additional cost of a 20/4 is worth it in terms of growth and increased Bud Quality/Size over a 18/6 schedule. I would love to hear your experiences.

Bend Her Over?
Any chance of super cropping a thriving auto on day 42? She hasn’t flinched at training yet; and got hacked on. I’m running out of vertical space with some developing runners. She’s going to stretch a bit yet, and currently 12” from light with 650 PPFD. Bend, or not to bend?

Reveg/Budding issue
What is my plant doing? the days are almost 15 hours long so I don't understand why it's budding still, I expected it to reveg by now but no sign of rounded single leaves still. The days are getting longer not shorter, end of next month is when the days start getting shorter.

Grow light question
I bought a cheap light by KingLED. It’s only 100 Watts and I’m unsure if it’s enough for one plant. The light has 2 switches, one for veg and one for flower. Should I always have both on since it will be an autoflower?

Irregular light schedule.
I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her? My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.
