Like 2500 watts for 1 plant to much
its more complicated than that. theres distance, spectrum, and real wall draw wattage and probably more i dont know about
No you can put as much as your heart or your pockets desire it’s just managing the heat and proper distance to your intensity think of the sun its intensity is so great but so is its distance
What kind of light?
Right. U dont want the extreme lighting too close at all. Like @blackthumbbetty said ot depends on the light.
Also the more light, the more food they require to photosynthesize. The more food they process the more co2 they require. The mor co2 the more light they can use. Its a vicious circle. And requires a FINELY tuned grow setup to maximize all variables. Lighting at a certain point without the other two becomes a moot point…
You’ve been given some good advice
This is a interesting read all though it doesn’t answer your questions I thought you might be interest
You want between 50-80 watts per square foot of light for flowering
It as mentioned there are other factors as well other than just how many watts
