What ppfd do you guys recommend for plants in veg? I’m finding that my light can be too strong at max power even at a 24” distance.

Put your hand under the light at the height of your canopy., if your hand feels comfortable under the light for 1 minute then your girls will be fine. Cheers

mars-hydro question
Before starting my grow, what is the most suitable light for my cultivation? Mars Hydro TS 1000 or Mars Hydro TS2W 2000 for a 120x120x200 grow room? Can this light be the heat source in the room?

Setting up air cooled refactor.
I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.

Viparspectra LED tips
I’m looking into buying a viparspectra in the future. Which one is best for one plant? I’ve been looking at the 600W one, but I don’t know if that’s the best option for growing a good yield plant in a 80x80x160cm tent.

Can you make an Auto flower by changing the light schedule?
Ok, before everyone jumps on this with the obvious answer - I understand that you don’t NEED to change the lighting for an auto to flower, but my question is can you, if you wanted to, flip an auto to flower by changing the light schedule to 12/12?

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.
