How much gram at 300 watt?
StDeacon
started grow question 5y ago
How much gramm does mine get from a plant when working with 300 watts full specktrum LED? Have I read the 1 gram per 1 watt is that true?

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?

Spiderfarmer SF1000 tips
Hello guys I've got a question about my new lights. I have the led panel from spiderfarmer SF1000. Any tips on how to use it? 😆 Should I dim it for the seedling stage or have it constantly at 100% power?

i asked this question once before where i had heard some people when they have a led with individual switches for veg and flower where they have both set to on and the answer came back that it is best to do this but my plants are almost 7 weeks and others here have a lot more bud

Supplemental light for flowering?
I have a 300w quantum board LED. Its a Mars Hydro TSW 2000. Should I add more light of a different type for flowering or should I just run the LED alone? I've heard people mention the UV-B lights.

Is 500 ppfd on new seedlings ok?
My light dimmer only lowers to 500 ppfd. I’m starting autoflower seedlings in a space tote before I move them into my perpetual harvest tent. I’m currently propping the light on its side so that the indirect light only hits around 300-400, as an attempt to reduce light bleaching.

Are these stretching? What should I do for the 2x top that barely sprouted?
Viparspectra xs2000. Just moved it to a 25" distance and 50% light intensity hoping it'll help, but unsure if it'll burn them? What should I do? Top 2x seeds JUST sprouted and are just barely above the soil. How to accommodate all plants regarding light intensity and distance?

Lower lighting at switch to 12/12?
Do you typically want to lower your lighting when you switch to 12/12? I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?
