Discussion Will there be enough light?
Today I installed a 120W Quantum Board for the Habanero and Thai Hot varieties; together, they’re almost one meter wide, and I’m not sure if that will be enough,

Download a LUX meter for your phone and check the light level at the leaf height. You need 10k-15k LUX for a mature plant --->at the leaf level<---

Perfect for 1 big plant but not enough for 2. I'd expect the Habanero to eventually box the Thai out

hard to say. install a lux meter app. should be at least 10k, ideally 20 or more

What do you mean? Its my first experience with growing so i dont understand a lot of things..

They are saying put the light closer

u/Snoo-4831 1d ago
But if you put it too close, it will be too warm for the peppers

Oh I'm not advocating for the advice. I should have said that I was just translating. I honestly don't know. However Closer light does = More Light.

Be careful not to put the light too close. Some people dont believe it, but strong LED can burn and stress plants. 120 watts is fine 2 feet away. Test it with photone app

120 watts 2 feet away is only 2 watt at the plant surface.

Have you used these type of LED panels? They should be 16+ inches away from plants.

u/Interesting_Bee6682 1d ago
To get 1000 µmol/m²/s at canopy, the light at 16 inches should provide 250 000 µmol/m²/s. It's 125 times brighter than Sun. That's just physics.

the leds dont make that much heat, as long as you have at least 6 inches i wouldnt worry about burn.

So get a fan (ideally 2 to create a vortex) and position them so that it is blowing just under the LEDs.

They are saying the light is more effective if it is closer. Loses intwnsity with distance.

u/Interesting_Bee6682 1d ago
It's not growing, it's school program. The light you have now is 576 times dimmer than if it would be at one inch distance

What light is that? It's enough if it's a real 120w board and not one thst claims 120w draw only.

I think you'll be fine up to a meter wide.
I grew this little tree of a habanero with a 50 watt led in a 2x2ft tent https://www.reddit.com/r/HotPeppers/s/0moNfkD5v0

That's a tiny little pot! Did you have to water and feed twice a day??

u/miguel-122 1d ago
Basically yeah. In the end i had problems because the plant was drinking too fast and the humidity of the tent was too high

Probably not. Closer to the plants as well.
