I am also interested in this... Are you scrogging? What's the strain? Type of lights? What nutes? God I hate hydro lol....
Well, since I'll be out of the loop for a bit I'll fill you guys in on some secrets.
#1 I don't top, fim, or lst my plants. No scrog, no SoG. I only defoliate 1, yes 1 leaf per plant, per day. I just pick ONE that is the biggest light blocker and remove it. I have been using a undercurrent, top drip, recirculating water farm kit now for 5 years. My average net is usually around 50" plants, yielding 1/2P each. 6 pounds for 4 months.
#2 Lighting: 2800w (1 5500k 1000w, 1 4300k 1000w, and 2 4300k 400w) in veg, 2000w (2100k) in bloom.) Run in a 4x8 tent with 400cfm exhaust, and 400cfm intake are to displace heat. I run the 2 1000w MH and 2 400 HPS bulbs during transition to bloom. Once the white hairs emerge a couple weeks later, I pull the 400w HPS, and switch the 1000's to HPS. So, 2800w MH veg, 2000w mh/800w hps for transition, 2000w hps for bloom.
#3 Nutes: general hydroponics flora series. gro, micro, bloom, calimagic, and sometimes instagreen from grotek. PH is allowed to wander between 5.5 and 6.1 . PPM is typically 50ppm for clones, 100,200,400,1000ppm for weeks 1,2,3,4 of veg. 400,800,1200,1600ppm for weeks 2,4,6,8 of bloom. I run a 3/2/1 in veg, 3/3/3 in transition, and 1/3/5 in bloom (not npk ratio, this is my gro, micro, bloom measuring ratio. ex: 3tsp gro, 2 micro, 1 bloom. 3/2/1) That's not actually my blend. My blend is consistently added in 4 gallon increments, adjusting ph according to the circulating undercurrent needs. I use a controller bucket to monitor PH and ppm. If it's showing a PH, I can adjust it, wait for the pumps/watering to cycle a couple times (1 hour time) and have my correction number. I can recorrect as needed, and it just continues. Also, I found that I have no need to actually switch my water out on a routine basis. I have learned that I can get away with 1 time per week, pumping out 4 gallons of old water, and replacing it with new water. I don't see root rot and I'm certain I don't have a salt buildup issue. I simply continue to top off my controller with PH corrected water or nute formula, and once a week, i will pump out 4 gallons and replace it with fresh water.
#4 You might hate hydro, but if you are good with hydro, you can make some serious shit happen. They absolutely go beast mode while in veg. I also like the 5 gallon bucket setup because I don't need to fuk with transplanting or dirt. My roots always have plenty of oxygen, nutes, water, and plenty of room to grow so it makes for a pretty legit setup. No transplant shock. Just set it in there 1 time and your golden till the end. You monitor the water, make corrections, and watch things go ape shit. That's it.
#5 Taviddude: Ounce nugs man. It's a forest when I'm done.
#6 This is the AK-47 strain.
#7 I was still in veg. I run 10 days in clone, 30 days in veg, 60 days in bloom, 15 days to dry, and 5 days to set it up and do it all over again. 120 days, 3 times a year is what I run my schedule. They are usually 24" going into flower and will finish anywhere from 44-50". High numbers being 15oz on 1 plant, low being 7oz on 1 plant.
Been doing this 10 years. Been on RIU since last month.
Any more questions?
