[QUOTE=Rick Ratlin;6350509]al, I'm having trouble with my cool tube/ adjust a wing set up. I'm not sure how much space to leave between the glass and the aaw. I've also got some hot spots, but not directly under the bulb, only on the sides. Which holes do you use in the wing to attach the wire, there are multiple options, and I'm not sure which is best as I don't have a light meter. I also can't make both the cool tube and aaw level, so should I shoot to make the aaw or the tube level? Thanks

While you can do it, it's a bit tight for my tastes and can lead to poor bud density down low on the plants.
Not very. If you're getting algae groth in the tanks, block light to them. If not, they're probably shaded enough for you to not bother.
Waterfarm can allow roots to grow down into the res below the media container, leading them to be constantly submerged. When this happens, Waterfarm begins acting
[QUOTE=Al B. Fuct;5470190]What's a YJGF?
If your res size is well matched to the number of plants, the TDS will remain relatively constant as the solution level drops. 5L/plant is about right. If the TDS is remaining constant as the nute level drops, you don't need to top up. If the TDS is rising as the level drops, the res tank is too small. If TDS is falling as the res level drops, the tank is too large for your application.[/QUOTE]
