Here are a few of the Blueberry x Alien 4 in the other end of the same setup...4 different phenos but not far off from each other..
Right now I have 4k over an 8 site set on 25" centers basically....I ran this system on 50" center and didn't like it near as much, water flow and water level issues and some other stuff
Lovin the system so far, love that you only have a 4 gallon soil and space commitment from veg thru flower...10 gallon pots eat alot of room and I am gettin the same outta the 4 gallon smarties, way cheaper and easier to move around for my old ass
1/4" holes right thru the center of the existing holes in the halo...I'll put up pics later
Hard as hell to keep your ppm's low, topoff res is at 400-500ppm to hold 1000-1100ppm in the system
