I’ve heard great things about those QB lights! Fellow noob here, but I wonder if maybe they’re a little too close? Maybe notch them up a few inches?

I didn’t realize you were in your second week. You can go at a quarter or half strength off the flora nova schedule, just keep everything in proportion. So if full strength calmag is 3mL, cut that in half as well.

I hope you love the DWC. You can grow monsters. They are calmag hogs, especially under the LEDs. I aim for a pH of 5.8 as well. Here is a pic of my girls in the 4x4: a GG4 at 86 days on the left and 2 NLs at 56 days.

Looks like you're running 4 cobs. That's going to be my next diy project for tent [HASHTAG]#2[/HASHTAG]. What color temp did you go with? My qb's are 3500k & I'm thinking about two 2700k cobs and two above 4000k
 
I got 3500k’s. Not at all handy or I’d be hanging a pair of 2700’s as well. Where do you get 2700k cobs?

Both girls are looking great. This grow will give you a great perspective about what kind of maintenance each method involves. I know with DWC when they get to be monsters there’s a gallon that needs to be added back in every day. Gotta watch that water level and keep it at a half inch or so below the basket: I only know because I got caught.

Man o Green helped me build this auto top off system. Keeps all the buckets filled. I have to go away for 5 days and I was sweating it. Now it’s smooooth sailing. I’ll be showing the thing off in my journal next week. Holy shit he’s a life saver!

Ooh la la such lovely root porn! DWC brings out the geek in all of us :smoking:

Please ask him about the 2700s for me. I’m serious about putting one or 2 in the tent.

Score! Don’t know how I missed that! She’s a beauty.
Yea...that 2700k cob is beautiful when lit. It's the closest to a genuine HPS I've ever seen. You can run those suckers closer to the canopy & get yields that 3500k just can't produce.
