I'm thinking of using either Bridgelux EB or Samsung strips. Or maybe a board style. This would be for a 2x3 or 2x4 space. How much light do the little ones need? I see a lot of recommendations of 40-50w per square foot for flowering. So here are some questions;

How many PAR watts or PPFD do plants need for the seedling through vegetative stages?
What is an efficient way to get those numbers considering the initial costs and cost of operation?

Thanks in advance for any input

I built a diy board using samsung lm561c flexible strips mixing 5000k and 3000k using a simple constant current design using 6 segments in series. I made eight of these strips or cut them from the roll. Each segment holds 7 diodes for a Vf of 20.3v x 6 = 136v. I connect all eight strips in parallel and have one negative and one positive wire which I connect to an hlg-185h-c1400b driver for a 160w board mounted on a cookie sheet 24" long. Check out the various samsung lm561c strip threads

I've been looking at the rigid strips with the leds mounted on a board. DId you use the tape the kind that already has adhesive on one side? Where did you buy it? Ebay has a lot of the flexible strip leds but not a lot of info on the actual leds.

you should look at our new hardstrips, we can supply with double sided adhesive strips if required
