I already have those drivers. I goofed up my math on my build, so I have room to use up. Thanks for the info. The 4in1 is what I was looking at. I thought I could adjust down, but needed a little confirmation. I

I was looking at rapidled and they have the semiled total uv. Anybody have any experience with these? It states a max of 1000mA, is this a hard cap or could they run @1050mA?

I'm an salty dog from the aquarium industry. I have a ton of actinic flourescent kicking around. Should I fire up some of those on this run until I can get some added to led panels?

My bad- 3 panels of 8 cobs each over 12ft by 3.5ft The light mover is moving each panel about >30". It's got great coverage, no dark spots, just a solid path of light. All the shadows moving around opening up the canopy. Please excuse my ignorance - who/what is sgs? Does the extra red improve...

Yeah, it was awhile ago. As far as the space, it's 3 panels over 12'x40" on a light mover. I see my mistake after looking at supras spreadsheet. But it looks like other people's setups shouldn't work either. I must be missing something, I'll get back at it and see if I can find another mistake...

Just to complicate my mess- Should I use up any extra volts to add some UV or additional red?

I've built a modified version of @REALSTYLES 8 cob on a 10"x24" heatsink. It consists of 4x cxa3070 3k and 4x cxa3590 5k. I have 3x MW hlg-185h-c1050a drivers. I need to order 3 more. The drivers are running the 3070s fine and as stated in the previous post won't run the 4x 3590s. Where is the...

Why only 3 cxa or 4 Cxb? Using @robincnn math - vf~35v x 4= 140v Hlg-185g-c1050a 95v-190v 4cxa won't light, 3 will but no dimming, and 2 will with dimming. What's going on?

Thanks buzz that's helpful

I've got a TDS meter.

I didn't have faith in the cheapo soil kit. I guess I'm not understanding an ec meter. Don't they just check total ions in the water. Won't an ap system have too many extra ions to get a worthwhile reading? How do you determine just potassium level? Are you mixing a stock solution and using the...

I like those bathtubs! I have been planning on using them as well.

Thanks buzz. A tsp per gallon. I just dosed 1tsp/50g based on a planted aquarium site. I understand its hard to overdose. That was suggested twice a week. Any thoughts on using rapitest soil test kit to check the level? Or is there a test kit anyone would suggest for potassium?

I just picked up some potassium sulfate. I think it may be 0-0-50, I'll have to double check. How did you mix it up for your foliar spray?

I'm building my system around two major parameters for cannabis. PH at 6.2 and temp at 68'F. That said I just picked up 10 silver dollar sized red pacu and will be adding crystal red shrimp to a separate area in the system. I wanted to grow tiger prawn, tilapia and pot outta one system. I've...
