GreenGalaxyFarm Posted February 6, 2023 Share Posted February 6, 2023 ill be spending the next few weeks studying and building a modular nft hydroponic system going from a 12 plant to 24 plant and eventually 36 plants total in a 2.4x4 room. id like to use this thread to document research into my specific system and eventually seed, and or, clones through harvest. 1 Quote Link to comment Share on other sites More sharing options...
GreenGalaxyFarm Posted February 6, 2023 Author Share Posted February 6, 2023 can i also add in a post to thank you for reading into my future project and i hope to hear some of your input as this system and grow progresses 2 Quote Link to comment Share on other sites More sharing options...
GreenGalaxyFarm Posted February 6, 2023 Author Share Posted February 6, 2023 (edited) i bit of a background as to my grow style, i've been doing seeds into soil under the sun for years, using basic fertilizer. incorporating methods such as koi pond water feeding and worm bin teas. this has always been sativa, and i've put my head towers growing both sativa and indica side by side in a hydroponic system as a means to entertain myself and better my understanding of it least one hydroponic system. enter nutrient film tecnique. im have completed the drawing phase of the tubes and reservoir including sizing of air pumps and water circulation pumps. these will be added in phases and eventually consist of three separate reservoirs to tube 1:1 ratio. the purpose of having three is redundancy only. my list as of now on what needs to be done: -demo ceiling of flatlet. -seal and insulate roof with poly panel boards -fire retardant treatment of wooden trusses -run electrics and timers and generator relay. -150mm ducting 150mm duct fan and rubber clamps -fit and install digital ballasts 6x 600w with superboost 690w which ill be running at in flower. 3 on generator + grid, 3 grid only. -install reflector hood at 7ft and bulbs. mh for seedling and vegetation, hps and or, cmh(depending price at the time) through flower. -mount 2x 12l dehumidifier at 6ft height. one one generator the other not -fit and install 2x 14000btu ac. one one generator the other not Edited February 6, 2023 by GreenGalaxyFarm 1 Quote Link to comment Share on other sites More sharing options...
GreenGalaxyFarm Posted February 6, 2023 Author Share Posted February 6, 2023 (edited) so im keeping by the list, at least for day one. builds never go totally as planned but we can try. -demo ceiling of flatlet [DONE] -seal and insulate roof with poly panel boards. oh and windows. when i am done installing these ill need to remove the particulates in the room both suspended in the air on walls, windows and the floor. and after clean with some type of disinfectant. this has probably been asked a million times but what solution do you use to completely eradicate possible contaminants and pathogens on surfaces of the grow room/tent..

GreenGalaxyFarm Posted February 8, 2023 Author Share Posted February 8, 2023 (edited) ceiling, batons, isotherm insulation removed. had one quote done today to insulate and will get more tomorrow..hopefully ill find an option that isnt gonna blow the budget of the whole operation. last resort ill have to do it myself. some plaster work and painting needs too be done in the meantime.

GreenGalaxyFarm Posted February 11, 2023 Author Share Posted February 11, 2023 (edited) what is up 420fam! as it is almost such time i'm taking a toke break and updating the thread. everything i got thus far is from a local hardware not a km from me, i couldn't believe it was convinced i need to go into town, which i wasn't keen on tbh. in any case the pictures will tell the story but ill mention details. completed about 60% of the support frame. completed 90% of the 110mm tubes. attached castor wheels to base and it glides around like a cloud. need to run into the hardware shop to swop out some unneccessary stuff and replace with things i didn't know we need. edit: uhm yah so the camera, its an old samsung galaxy under hps lighting, its not working well due to screen breaks i have no other option other than to use this one or bother fiance for hers which i dislike to do. so sorry about to trash pics. and please ignore the wall, running 1200mm mylar diamond pattern across all of it as the build progresses.

GreenGalaxyFarm Posted February 21, 2023 Author Share Posted February 21, 2023 So we got a decent qoute for foam spray insulation. People insulation doesnt come cheap at all even my calculations to diy with isowall panels ended up breaking the budget..but okay still cheaper over the next few years than buying large led fixtures. Stuff has been arriving in the mail. The outlet manifold of the nft is done. Water pump is in and air pump came yesterday but without any silicon tubes so i need to run in tomorrow for that. just installed two smoke alarms as well. Basically only waiting onthe moulded net pots made spicifically for 110mm gro tubes. In 20 rockwool cubes im germinating some seeds. I had the e-m seeds collection from biltong n budz in cart but found out totemic has some bobbys widow x gorilla cookies f2 in stock so i went that route instead. First ones should pop tomorrow Doing 18 of them in hydro and 7 in soil for growth comparison. Ill post those pics and the finished nft when final holes are drilled and pots inserted. 4 Quote Link to comment Share on other sites More sharing options...

Naughty.Psychonaut Posted February 22, 2023 Share Posted February 22, 2023 What's your feel on the size and amount of plant in that NFT setup? I am assuming all 36 plants go on the 3 tube system, if so you going to keep those 36 plants relatively small? I am not thinking in terms of grow space, but rather root space. Personally, I don't mess with hydro, because of my experience with it. I notice is the gutter system may not support big root systems, this is why dutch buckets, DWC, Autopots, Rockwool bricks flood and drain tables, Ebb and flow systems all became a big thing in hydro cannabis growing. NFT is really only for a bunch of small plants such as all the FMCG crops. works nice in vertical farming setups where a bunch of small plants are grown and crop is rotated monthly. Even when growing stuff like spinach and other leafy greens, all tiny plants, if ones root system gets a teetsy bit bigger than the others then the whole NFT flow gets messed up. If the first plant sucks up too many nutes the rest don't get any..... NFT systems are such a headache brother, and when growing cannabis you want a biiiiig thiiiiiick healthy root system. when looking into hydro growers you'll notice that they always show off their roots, cause that's the important bit. As always, the knife cuts both ways. potentially what you could do is keep the light on 12/12, never veg, put clones in and flower them all right away. would give less root related problems. otherwise, looking good man looks like you got a big plan and I am excited to see how this plays out. 2 Quote Link to comment Share on other sites More sharing options...
GreenGalaxyFarm Posted February 22, 2023 Author Share Posted February 22, 2023 Yeah worried about the root development as well. But i assume that these small plants, photos vegged for only a few weeks, and autoflowers together with 6/2 and 4/4 lighting might help in maintaining size. Is trimming large roots recommended? Im not running 36 on the first attempt have only 27 seeds germinating and some of them are going to soil, 18 will go to hydro. Have solved the issue of nutes stopping with first few plants, the irrigation pipe get drilled and connectors inserted which cut off to individual 3mm feeding tubes running out from the 20mm. 1 Quote Link to comment Share on other sites More sharing options...
GreenGalaxyFarm Posted February 22, 2023 Author Share Posted February 22, 2023 (edited) If the roots still go to big ill need to add support to the frame and go up to 150-200mm tubes. Really just hope it works out as is. Starting the genie at night is going to be labor inntensive enough with all this loadshitting Edited February 22, 2023 by GreenGalaxyFarm 1 Quote Link to comment Share on other sites More sharing options...
