People have been running sealed rooms for quite a while...So if there is a lack of oxygen during the dark period that slows down photosynthesis it is probably made up for with the 1500ppm of c02 during lights on...Without the sealed room it is difficult to maintain these high c02 readings..
The sealed room also seems to offer a little more security from odor escaping...
I went with 40 inch centers and 40"wide...This is a test run once the 13 gallons get here I may take out a couple rows and make them wider and longer..JACKWhat center distance did you go with? I read from start to finish so I wouldn't be "that guy"....
Looks good, I got a 16 as well, haven't set it up yet. The 13 gal sounds badass, but wasn't out when I ordered mine.
I veg with half the lights..When it comes time to build my flip flop I will have you build it ..Room #2 is not complete waiting on the 13 gallon buckets...Thanks bro :smiley_joint: JACKHi Jack, awesome setup. Would luv to have been the builder of your lighting controller/flip. Are you vegging with half the lights? If you have a custom lighting controller, you can veg with all 30 lights on in each room for 6 hours (12 hours for both rooms). Then for the remaining 12 hours, you can cycle half the lights in each room from off and on, every 1 or 2 hours. The ballasts can also be shut off between each flip cycle so that the flip relays don't arc.
good to see you brought the thread back....sucks ya had to take it down for whatever reason or dipsticks mentioning shit.
the grow build pics were fucking epic!!!
whas your thoughts on the 2" pipe....have you had any root clogging? if so...
how common is this in these type of systems?
I have had zero issues with the Under Current system...JACKbump maybe?
Thanks Brothats beautiful bro
Big ups SWAY...:rockReally impressive grow u got goin Jack, definitely inspirational! can't wait to see the room at harvest time...i bet u will get a gram per watt no problem, much respect.
Sweet I have not been to the farm in like 2 weeks and couldn't open your thread. Found it reopened, to my relief. Plants are going crazy. Peace.
This is my first run with the Under Current System, The rooms are powered by 2 x 200 amp sub panels and 1 x 100 amp sub panel,The plants where veged 1 week with 15 k and 2 weeks with 30 k, Trimming is done with a trimmer and by hand..Big plants and vertical lighting are the only way to go in my opinion..JACKMan you not messing around are you! Few questions?
1.How are you powering 60-1k lights and a 20ton A/C?
2.How big will those girls get and how many weeks under 30k lights?
3.How in the Hell do you trim all that?
I got a 12x30 room sealed and want to maxiumize the space meaning getting the most bang for my space. Is this the way to go? Plus we been running the lights off 12v D/c Battery banks. No genarators or electric powering our lights ALL D/C POWER running inverters. Are lights are 6-1k and 6-600watt all hortilux hps with the 4ft hoods with Co2 sealed room. As of now we running 2-4x8 hydro tables with 108 each table and 60 buckets. I'm just wounding if we went the BIG PLANTS way if we would maxumize our yeilds. Any info would be thankful.
Hey Jack much props and respect bro. I'm wondering if you can spin those plants in those boxes? actually bout to build a replica to yours... thanks for sharing the dream idea with us. Peace HDK
