The ppm of the water in 110

Last Feed as follows: Flora micro - 7.5 ml per gallon Flora gro - 10ml per gallon Flora bloom - 2.5 ml per gallon Cal mag - 3ml per gallon. Came out to 1039 ppm at 5.91PH Using tap water, RO not available. Thank you!

Anybody?

Hey guys, still new to growing (3rd one) this is my first coco grow. Using general Hydroponic trio. Germinated july 21st. I noticed with my new DIY LED I'm feeding alot more this grow. Had nitrogen deficiency problems and corrected with all plants. Last 3 days I fed 1000ppm with added cal mag...

I've only read good things about cree, so I wanted to stick with them.

Thank you, failed to mention this light is just for half of my tent, a identical light will be made for the other half down the road.

Hello guys, thought I would share my build and ask some questions as well. I've been in the middle of building a 4'x8' grow tent with all the good stuff. Right now I'm building my first 12 3590 cob LED grow light at 640watts and 2.8 amps. I have 2 drivers... each driver is 320watts and 1.4 amps...

That sounds awesome guys, I appriciate you sharing your experience with me, thank you. Looks like I will stick with 12 3590s, x2 meanwell 320watt/1.4 amp. Puts me at just below 1000PPFD. But far more important, I understand what I'm building now!

Yeah that's correct, 12 cobs - 2 drivers - 4x4 space. I'm starting to wrapvmy head around all this thank you a bunch. If my understanding is correct, watts = yield (predominantly) correct? I may be thinking of using 480watt/1.4 amp if my thinking is correct to increase yield.

awesome, been playing around with the calculator now that I have it working properly. Seems to me these numbers above are good?? I want PLENTLY of light for flower. 929 seems on the high end right? why is there not an option for watts? how do watts come into play? Should I stick to the 220 watt...

Dang, thank you for all that info. That's exactly what I was looking for. I'm going dig in tonight and try to figure out how to open that dang file. I really appreciate it guys. Thank you!

Ahhhhhh okay, I'm just trying to get ideas, I dont want to drop 1k in lights and it not be enough output.

I'm just trying to figure out how to open the .class file now so I can dive in. Thank you! Looks like I need to revise this light

Sethimus sent a link over with math formulas so I thought that was the calculator. Thanks for the kind words

I will have 2 of these lights for my 4x8 grow tent. Each light fixture is for a 4x4 area essentially. I've tried finding a simplified version of the calculator but that formula looks a little complicated for me. I'm trying to wrap my head around how you get the PPFD calculated. Thank you for the...

Hey guys, I have my frame and everything measured. Plan is to use x12 CXB3590 COB in a 40"x40" frame. x6 3590 at 3500k and x6 at 5000k. 2 meanwell drivers 320watts at 1.4 amps in a series of 6. It's for my grow tent which is 4'x8'. I've been searching forever and realized it's much cheaper to...
