I have a few questions and maybe I can get some help,suggestions and assistance.
So, I have 2 200w bars. 1 bar houses 4 cxb 3070bb 3500k on 120mm sst heatsinks from ngl. bar 2 has 4 cxb3590 3500k on heatsinks from cutter,140's I think. Both of these bars are run by 2 185-1400 Meanwells. The 3590's barnhas to be rubuilt due to it being shorter than the 3070's. Did'nt have enough angle alum. left. All bars will be 48" long going forward.
What I'm wondering is.
1. should I continue with the bar style now that I.m going up to 12 cobs?
2. If so, what should the spacing be between the cobs on the 200w bars as well as the new bar being built. cob spacing, center to center. This is the one that is really bugging me.
3. I'm assuming and I have been told, the 320w bar should be raised higher than the others, is this with the reflectors(ledil angelina)on? I do use reflectors now. If I run the 320 watter without reflectors will that then compensate and allow me to run them closer to the height of the 200 watters?
All this will be going on in a 4x4 tent lol. Any thoughts,help is appreciated. Also, can someone point me to the thread that shows you how to calculate ppl and ppfd for my area? My search kicks me off the site when I hit enter.
