Welcome to the forum.

It’s a 400w light, so you can probably go with 2 plants.

You want a soil buffered for cannabis, so Fox Farm soil, Promix, Roots Organics, or Black Magic. Stay away from Miracle Gro, Vigoro, and Scott’s products.

generaly a 400 would have a 4ft veg footprint and a 3 ft flower footprint – what is you grow space size ? example: a 3by2.5 with 3 five gallon airpots and 3 gallon pots.( some say that a plant need 2.5 feet for proper growth) got 3 massive high yielding plants and 3 I would say OK - realy pushed that growone big consideration was ventilation

Earth Dust from The Green Sunshine Company is great. @MeEasy has a thread dedicated to it. Those of us who use it love it. So simple…just water.

There is no such thing as plant number to light. It’s been and always has been watts consumed to square foot. How many plants you want to cram into that equation is up to you. The old standard was 50 watts per square foot in the old days with HPS/MH and then burple junk and cobs came out and then the number was 30 watts per square foot and now it’s back up to 40 watts per square foot as LEDS advance…

I had a Cree Cob before moving to HLG
They generate some heat so make sure you follow the hanging height recommendations
