BonjourHey all. New to the forums. Just built the 400w cxb3590. Now I want to upgrade the veg room. Size is 8'x7' with 7' ceiling. What would be the best cobs for the job?
Hello there. Check out Pacific Lighting Solutions. Greengenes will help you out. Or better still, look him up here on Roll it up. He's like one of the first cob system builders. Got this thing crackin'!Would anyone have a link to a solid, cob build that would replace a 400w HID? Or suggestions? I'd like to use 3070's bb bin.
As far as color. I keep seeing people using 4k. But my mh is 7000k. I also grow assorted veggies. Will the 4k work or should I run closer to the 7k?Bonjour
Cxa 2530 would be great imo!

If you run veggies I would go for 4000ºk because of the lack of red in 5000ºk and 6500ºk!As far as color. I keep seeing people using 4k. But my mh is 7000k. I also grow assorted veggies. Will the 4k work or should I run closer to the 7k?
Tomatoes, green, jalapeño, and red cayenne peppers, peas. They all produce fruit under a 1k mh 7000k. Running 18/6If you run veggies I would go for 4000ºk because of the lack of red in 5000ºk and 6500ºk!
But I don't know if you really need some red for the kind you grow!
But I guess you have a vegg and a bloom period as well as mj...so 4000ºk imo!
Maybe you could tell me what kind of veggies! ?

dont cheap out. 3590s will pay for themselves and a larger heatsink is usable foreverWant to make 2 42" strip lights using cobs and this heatsinkwith passive cooling. Would like to use the most efficient cobs/driver I can, at a reasonable price. Im thinking maybe 5 cxb1507 or 1512s but not sure what to get. I see on the mouser site they are only available in 2700 or 3000 color. I was hoping to find 3500 or 4k as this will be used to grow edible houseplants, lettuce, tomatoes and peppers primarily. Im open to ordering from anywhere that is reputable and would really appreciate it if someone could give me a complete parts list for what I need, including cob holders (if necessary) reflectors (if necessary) etc. Id prefer to have a single driver for each strip and the environment is in my basement where temps are usually quite cool, close to 65F. I dont want to bother with fans, but there is a fan in the grow area, so there is some airflow available. I did some rough calculations and it seems that there is about 15 cubic inches of surface area per inch of this heatsink. So if it is necessary to have about 15 inches / watt of heat dissipation, you could have up to 40 watts / strip of heat, without going to active cooling? These are really rough numbers and I know some of you are much better at figuring this stuff than I am so any advice is greatly appreciated! Also Id like to wire these in series instead of parallel for safety reasons and I have thermal paste and kapton tape and basic tools already.
some people want instant gratification. im more of a "hey the efficiency upgrade of this component will pay for itself in 3-6 mos and keep on giving for a decade at a return i couldnt make in any investment" kinda guyCXB3590 are the best why do you guys keep shorting yourselves. Even @Greengenes707 is gonna start making 3590 panels soon the 3070's are gonna be a thing of the past.
Won't tomatoes jalapeños pepper...grow better under an hotter spectrum?Tomatoes, green, jalapeño, and red cayenne peppers, peas. They all produce fruit under a 1k mh 7000k. Running 18/6
Both peppers and tomatoes will always bloom and keep blooming until their death.Won't tomatoes jalapeños pepper...grow better under an hotter spectrum?
Maybe not since it bloom in summer??
There is a veggies section you should ask there what is the best led/cob ºk for it!?!?
There's a 6500ºk who is close to 7000ºk!
