When to put the light on?
Panzora
started grow question 5y ago
Hey there, Do you need to put the light on the pots directly after you planted the seeds in the ground? Or do you need to wait untill they poke true the ground and then put the light on them?

Plant can't absorb light till leaves open. But I leave the lights on anyway because I don't mind paying my electricity bill.

What distance would you recommend from the plants at the beginning, the lamp is dimmable. Start with 25% light intensity in the first week, right?

3000 watt power use
This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.
