If you've been on the fence this may help you decide which side to get off on. This grow is a RDWC in a fully environmentally controlled space running 18/6 with CO2. YMMV, objects in mirrors are closer than they appear, and all that.

Damn Rider that's a forest you got going there. Your gonna need some side lighting possibly.

Side and center lights would be great in there, hope you have 10ft ceilings unless you are just growing hemp for rope and whatnot... Those must be the 95 cri strips? BTW how hard are you pushing those?

This is the perfect example of not seeing the forest because all the trees. Your doing an awesome job rider.

Good eye, THT! Yeah, I added two CXB3590 four cob lights to the mix for center side-fill. There's zero room on the outside ends of the tents for lights. I've been running in the neighborhood of 1000ppfd with the Samsungs and the Crees are filling with 850ppfd. The strips are the 80CRI 3500K dual row FB24Bs, at four per side driven by two HLG-600H-48As. The Crees are also 3500K and each group of four is driven by an HLG-320H-C2100B. I've been able to keep the strips about 6" to 8" off the canopy with no light burn or heat problems. Temps were set to hold 80-85 with humidity at 65 to 75% during lights on, and 70-72F during lights off throughout veg. CO2 kicks in at 1000ppm and off at 1200ppm, but I'm flowing hard so it typically rises to about 1500ppm a minute or so after the solenoid stops the flow. The reservoir is set for 68F. I was using Cutting Edge Solutions nutes but switched up to Flying Skull for flower. I'm going to stick with Flying Skull from now on.

I kinda screwed the pooch there, didn't I, tre33man. I'm going to have unzip the top and let them have the extra headroom. I'm thinking Panda film to fill the space. This weekend I'll reconfigure the RDWC to center the plants on each side of the tent so I can get another 8 3590s in there for side fill. Environmental control is going to be sketchy but I don't see any other option unless I supercrop the hell out of them.

Humple! You're still around. Cool. I kinda took a hiatus for a while. It's good to be back to growing again. These strip lights were kind of a lark. I was looking at getting rid of the old 8' T-12s in the studio and while I was looking at the leds I started thinking that they may grow good weed. Originally I was checking out the Samsung H Series but @tomate turned me onto the F Series and I ordered a bunch of both in and started testing. I'm digging the hell out of these F Gen3 strips. Damned things return 170+lm/W! They use the same LM561C leds that the HLG guys are using in their Quantum boards. And they are way cheaper to build than a comparable 3590 setup. Killer penetration and no hot zones. Kinda hard to beat.

What are you using for bulkhead connections to your totes? Everything ive tried above 3/4 inch has leaked on me.

Look for pond supplies they do the larger plastic weld bulk heads which won't leak and not expensive either.

Uniseal bulkhead fittings are the only way to go. The ability to handle an offset angle makes them perfect for use with totes or any other surface that isn't perfectly perpendicular to the line of pipe. I'll never go back to a hard mounted solid fitting.

The key to using Uniseals without leaks is to have the proper sized hole saw and to dress the hole after to make it smooth and burr-free.
