I decided to dump that entire system this past Oct, finish out what I had and purchase for all my rooms the CAP Ebb and Gro System.
30 Bucket Room, and it's the healthiest grow I've had this year. Meaning zero deficiency problems with the plants, in this room. When I used coco there was always something I couldn't get quite right.
Using 2 1000w in this 30 bucket room, the room is a little tight, I may end up moving some buckets to another room for better coverage.
Also I have two other rooms that I've installed ebb and grow systems:
42 Bucket Room: Running with TWO controller buckets from the one water reservoir, current strain God's Gift, this room has 4 1000w
24 Bucket Room two strains, Bio-Diesel and Purple Kush, running 2 1000w in this room.
30 bucket room has several different strains: Blue Dream, Bio-Diesel, Mr. Nice( which is turning purple nicely) and Chernobyl.
Timers for all Controllers: Floods every 6 hours, that's it.
Nutes: General Hydroponics, using the simple recirculating feeding chart right off of the first page of their website, using this for all three 55 gal water resorviors.
The plants are the healthiest I've grown in the last six months. I've compared this chart to previous charts and it looks like they have changed their charts closer to that lucas formula some people use. But I haven't compared them in detail. During transplate I use B vitamins right after transplant.
Additional Nutes: FoxFarm Cha Ching is the only other nutes I add in the last 3 weeks of flower before flushing.
30 Bucket Room Air flow: NONE, that's right, nothing. Strange but true! I grow in a large warehouse, I built this room within the warehouse space and only used plastic for the ceiling section. Hot air from the lights flow out, daily temps with lights on are around 76 - 80 degrees and the winter nights bring 60 degrees to 50 degrees so it's actually been perfect. Basically just like the temps would be in the mountains.
42 and 24 Bucket Rooms air flow: is controlled with timers on inline fans with incoming air from outside and exhausting with inline fans from the rooms. Also using air conditioners in summer months to keep cool. The temps are kept in the mid-high 70's during the light hours and 60's non light hours.
