these are cree cxb3590 based diy lights which are the most efficient cob led emmiters, and are what the majority of this forum is using/switching to. essentially you can get the same amount of photons as a 1000w hps with 700w or so of cxb3590's so that gives a pretty significant heat and electric advantage. growmau5's youtube channel is the best place to learn about it, check out his diy led tutorials
I see, thanks for the info, how many are you running total?
what size room is that?
3500k is the consensus standard as of now and works great for both flower and veg. there's room to experiment there so do some research if you want but you don't have to worry too much about spectrum beyond 3500k cxb3590. my tent is 4x4 ft. it's always cool to see hps guys eager to switch to new tech i think there will be a lot of that in the future.
How many is recommended in a 15 x 10' room? You have approx 1 per square foot of plant space, this the number most are going with? I would be looking at roughly 90 of these to replace my 6 1000's in the one room.
this is where you have to balance startup costs and performance goals. my setup with 1 per square foot is pretty maxed out in terms of spread efficiency and intensity (low drive current). the most common and cost effective is to run the cxb3590's at 50w each and something like 2/3 per square foot. as the tech gets better we can drive the cob's at higher current and still get good efficiency, so the new standard cost/performance is more like 62w each which is a 1750ma current driver. you can start off with high current and less per square foot and add more cob's over time.
You can put the same amount of nrg through the 3070s as the 3590s at the low end at least. Difference is efficiency, for the same amount of electricity used, the 3590 is going to produce more light and less heat. I dont have the exact amounts, but for most users, growing relatively valuable crops, its worth the extra $$$ to get better cobs. If you are producing lettuce for personal use, probably not so much...
Do you think you'll take down 1.5 units out of there?
Have you tried dropping to 11 or less hrs of light? Might slow them mites down
prob somewhere around there plus or minus 50g
that's interesting i've never heard of that. how effective do you think that would be?
spider mites dont like to reproduce when they get less then 12 hours of light. They will still be there or they might even go dormant but all your trying to do is buy a little time. For example, vacuum the mites off the plant, clean your plant and drop the light hours to 11 on. It will slow the mites and speed up flowering time. Don't forget to clean the living shit out of your area after harvest.
ok yea that makes sense and is a good idea for me so i just changed my timer to go off 1 hour earlier... thanks a lot. and yeah anything specifically i should do after harvest for cleaning my room? try to vacuum every square inch? i want to do everything i can starting now to ensure i never get mites again, but also just to prevent future outbreaks b/c I think they likely came from my backyard/garden that surround the little building/room my tent is in.
Bleach the room and surrounding areas after harvest, you can hit plants in veg with mighty wash just read up the proper way to use it.
where do you get your lady bugs from, internet?
