Diodes are .2 w nominal, .6w max. 3w diodes would make it 2400w max. My suggestion is based on what worked fine for us, but many ways to skin a cat. The reasoning is that 2 heatsinks for 300w operation each costs (where i am) more than getting another board. These boards run fine with no heatsink up to 200w but ideally a little less. 160w is my sweet spot. Also means you get a bit better spread, lower hanging height and lighter fixture
Yeah, aluminium is expensive these days... You should be able to pick some up cheap somewhere tho and perhaps get someone to water-jet CNC it for you. There's a new board out on Alibaba: https://m.alibaba.com/product/60847528837/For-Plant-Grow-Light-QB800-301B.html?spm=a2706.8301176.prew843968.13.b7294d25bQqBlF
The fans require a minimum of 5V of DC power
You can just get the adapter for the fans... USB... https://www.amazon.com/AC-Infinity-Turbo-Adapter-MULTIFAN/dp/B01G47U2Z0/ref=pd_aw_fbt_img_3?_encoding=UTF8&pd_rd_i=B01G47U2Z0&pd_rd_r=ea63bb0b-ebe6-11e8-88d2-3b20857d970c&pd_rd_w=skEaO&pd_rd_wg=mEd5T&pf_rd_i=mobile-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=b98fa1a4-6e6e-4981-835c-7fb29e0f4dd2&pf_rd_r=TE5FKDMGFNCJYPSDPV2P&pf_rd_s=mobile-dp-sims&pf_rd_t=40701&psc=1&refRID=TE5FKDMGFNCJYPSDPV2P
You can also mount this thermal trigger on the back of the boards: https://www.amazon.com/AC-Infinity-Controller-AIRPLATE-MULTIFAN/dp/B078PY8L9F/ref=pd_aw_fbt_147_img_3?_encoding=UTF8&pd_rd_i=B078PY8L9F&pd_rd_r=5f6fb86e-ebe7-11e8-b84d-d3ea889372c2&pd_rd_w=5KIak&pd_rd_wg=sX0iv&pf_rd_i=mobile-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=b98fa1a4-6e6e-4981-835c-7fb29e0f4dd2&pf_rd_r=M5HJ9FBZVPSE9MBEWW3E&pf_rd_s=mobile-dp-sims&pf_rd_t=40701&psc=1&refRID=M5HJ9FBZVPSE9MBEWW3E
The thermal switching is really nice feature but is the fan itself any good? If using this for cooling boards/heatsink the fan should be on all the time anyway, wouldnt it be better just going for a tried and proven fan. Amazon gear doesnt really have a great track record...
Not sure... It's got raving reviews and the 120mm one is really powerful for such a small fan. I guess the thermal would be to get some control and prevent from overheating. I'm sure you could just use a clip on fan, but I like how these sit flat on the heatsink with rubberized feet. Apparently they are also very silent.
Nice, that looks like A great idea
I wouldnt trust amazon reviews too much, have you see the blurples they sell? Most of them have stellar reivews.
Don't use that, you will end up with tiny plants that yield one bud that's only enough to roll a joint.
Haven't grown aeroponically like that B4. I see some of the results people are getting and it isn't what you describe. Besides I don't have 3 months to veg. Quick and easy one week max veg straight to 12-12. That way a 50 day strain will get you 7 harvests/yr. 40 single donks adds up.. have a look:
Using clones?
Yeah, rooted jiffy's straight to 12-12. Healthy clones for sure.
