Hey there,

as I'm quite new to this forum and not nativ english speaking, I had problems finding a thread where this maybe was discussed or mentioned.

I'm doing a 28" PC Grow with 1-2 automated BigBuf SensiSeeds (can follow in signature) I realy did a lot of research, on soil, vert and all this stuff on my first grow with a 400W hps and a squarefoot of space.

As my growbox aint that big, I thought the "culterlux 30w" would fit in matter of size and Lumen given to a plant wich is realy close to the panel & very low temperatur inside the computer.



My Question is: If I should put 1 or 2 esl low watt bulbs in.
maybe a 11W vegilight and a 11W UVB bulb wich only will light 2 hours before darkness ( 18h LED & VEGI // 2h LED/VEGI & UVB // 4h darkness)

Another way could be the mix of LED and 2h of uvb, without putting in another vegi esl, because automated early flowering and a small height doesnt need an extra vegi light? right?

other small pc projects have somthing like 70-80Watt of ESL and work fine. my LED panel should be mostly arround this amount of energy provided to the plant. So LED panel should be enough on its own.
(the UVB thing to get the ladies into the mood for a nap is a nice upgrade, but not a musthave, right?)


a lot of talking...
I would be very happy if anyone could give some informations on this, as my LED panel just arrives today.



edit: and yes! being informed earlier would be better :thumbs:
edit2: I just read in a german forum, THIS 30W LED PANEL is calculated to fit a size between 40cm² to 50cm²

Hi lowbudge,

just wanted to ask why you use UV-radiation? I heard that it causes stress - especially with young plants? Do you have any positive experience with UV?

Thanks

UV is good for plants and doesn't cause stress. If it did, why would plants do so good under the sun?
 
uv-a is bad for plants.
uv-b ammount is higher at sunrise/sunset, so I try to immitate this higher amount of uv-b to let the plants feel more like in nature and lower the stress theoretical...

I have no expirence using this method, but I will try it, and maybe on the next grow I wont do, so it could be compareable.


Cheers,
