todo depende del tamaño de las plantas! tal vez despues de la 3era semana de veg es cuando realmente empiezan a necesitar mas luz!

First time growing indoors. I purchased a Mars hydro TSW2000 but the manual has no information…. It’s equipped with a dimmer but I have no clue on what the appropriate height & dimmer setting should be for seedlings or the height for the veg period & flowering period. Advice plea

If humans took weed to grow on another planet where the sun was up for 28 hours and down for 10 hours, how well would it grow? Would the plants adapt to the different light / dark times? Or maybe 24 of hours light, 6 hours of dark? Theories? Earthly Proof? Comments? 👽

Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?
My Blurple apparently uses 230W actual draw but is advertised as 600W. If that 230W value is correct, does that suggest my new, much more expensive QB is not as good? Will it make a difference to the plants health? What are the benefits from the QB? Thanks!

LEDs lumens
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

Eyeball and advise on my set up, and is this seedling stretching?
Is my set up good until my humidifier comes? (using inflow air from in-line fan with a tray of water for humidity for now). I set up an additional light because I was concerned that this bad boy was stretching and want to provide some extra light for lower canopy later.

Best Lamps
Dear fellow growers! I kindly ask you to give me strong advice on LED lighting. Specifically, which COMPANY and MODEL is currently THE BEST. For plants, of course - not for the wallet. Price and economic considerations are also important to me, but not the most. Thanx & regards

Lights too close?
While trying to figure out why my plant is so dwarf like I realized it might be the height of my lights. They’ve stayed that position ever since installed them. The problem is they’re basically at the ceiling of my box. Is my set up limiting its growth too?
