That's what I heard as well, the led might be 300 watts but the true power draw might only be 130w

So the lamp makes 300 watts and has a power of 124 watts plus 5%. If I now assume the 124 watts, there would normally be just under 100 grams or am I wrong?

How to keep room dark during flower?
How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?

When should I switch on the other half of my LED light setup?
Hi guys, I grow 6 plants in hydroponics in a 4x4 grow box and they are 2-3 weeks old (about 7-8 cm tall). I use MarsHydro TS 3000 LED (450W) which have 2 seperate LED panels. Right now I run only one panel and would like to know when I should turn on the other panel. THX

Lights for heat- 24/7 okay?
I really need the heat of the lights to keep the inside of my tent warm. To warm the air around the tent 24/7 would be expensive- much more expensive than using the lights all the time. But will this work with 24 hour lights? Will that stress the plants? Using auto flowers.

- I have a greenhouse ceiling that covers 50% of the terrace - should I grow the plants always under this ceiling, or if it is beneficial to expose the plants to direct sunlight? - If so, how old the plant has to be to expose it to the sunlight? I don't want to burn my seedling

Hi first time grower here. Been vegging 4 plants in 80cmx80x160 tent with 150W LED (Mars Hydro TS1000). Start of 2nd week flower today and I added another 150W LED. Could that potentially increase my yield? Thanks!
