100 watts will work great in there for veg. I’d definitely make it as tall as possible. Can’t ever have to much room vertically. Good luck with your new setup and happy growing!!!

You could get four 1-2 gallon pots in there easily and veg for around 4-6 weeks or until the plant is about 2 feet out of the pot. Then transplant into 3-5 gallon and flower. Or veg autos directly in 3-5 gallon pots and you could still get 4 in there. Be nice!! 👍

How many plants in a 70x70x160cm tent with 100W?Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3. Should I be going strictly off of PAR or VPD at this point.

Canopy clearance I'm growing a photoperiod and been using the SF1000d light. Having to run the light much closer to the canopy than suggested during the entire process. I'm in flower currently and she still looks healthy as close as 6 inches from the light. Is this normal? Is my light below spec?

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500 Would gladly use some help with my first grow 🙏 2 main reasons come to mind after googling: 1. I overwatered thinking it's hard to do since I'm using the Air dome. 2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

Wrong power cable in my LED light: still light when switched down off.Have you ever made this mistake? My second harvest was someway worst then my first. Sure I did some watering mistakes but during my chores in the room and in the tent, I found out. I used a random power cable on my PAR LED lamp so when It turned off still had some light on. Bang!

Will increasing light intensity restart stalled seedlings Seeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?
