I'm leaning towards the Samsung H series. They use the same LED's as the Quantum Boards which I like. If I understand correctly they have 96 diodes which is a 3rd of 1 QB 288, so I'm thinking therefore that 6 strips would equal 2 QB's. That should be adequate in the 4x2 I think.I'll save on the driver as well by not using the F Series.Hey, SC. Things are as well as expected. Yeah, I'm happy with my EB build, but still haven't been able to use them for a full flowering cycle; just popped a couple of beans this week, but won't put them under the big lights for a few weeks.
4 x 1120mm EB-series on a 2' x 4' would make a good veg light, but would only be adequate for flowering. At 4" above your canopy you're going to get ~375 umol/sqft, but from what I've read, the optimal number is around 1000, +/-. Why not go with 8 of the EBs? I expect your cost will be lower for equivalent umol output.
Regarding the PPF I think 1000 is too high, at least that's what other growers are telling me. 800 seems to be the optimal amount so that's what I'm going to aim for.
