I don't know the specifics of that lamp. For seeds I use some 20w "Cool White" cobs and a pair of "Cool White" LED T5s at around 15cm. When they develop into full plants I put them under my TS1000s at 60 - 70cm distance and no more than 25%.

Av got the light down on 5% because i just cant seem to dial it in, i have a 250-300w cfl im thinking of going to try that i think

I have changed my led to a 450cfl blue bulb now hopefully this is better now

Too many plants and not enough light

What light would you suggest for a 80x80x160 to start 12-16 plants while my 8x4 finishes flower

i flower 12 in my 8x4 tent

My seeds are in a 120x60 and I am using a pair of 90cm T5 LEDs, with 4 of these running betweem them...

I get them within about 20 cm of the lights.

300w @ 14" to get 400 umols in my 4x4.
I'd figure 200-300w would be more than enough for what you're looking for.

I think that light would cover a 2x2 tent slightly better than a 2.5x 2x5...but I agree, I have a hard time using these small LED boards for seedlings-they just don't thrive quite as well as under t5s, but I have done it several times. Do you have a lux or par meter? I usually dial in to around 10k lux for seedlings, then adjust from there. That might be something like 25% at 30 inches or more distance. Lux isn't ideal but it works fine for things like this.

I've got the same meter.
Running 18.5k lux atm.


Edit...Migro did a video on that meter btw.
Multiply lux by .023 and that will give you Par for Led.

Oh yeah, that's definitely the issue, seedlings don't grow much when it's that cold.

Lowered the 450cfl to get this and its about 6inch away from tops of seedling is that a bit to close,

Curios as to wether these heaters would be better suited underneath shelf the plants sit on, thoughts
