sorry noob question. What is nft?

Nutrient Film Technique

 

Basically a small pump trickles a thin "film" of solution over the tray that the roots sit on. Not submerging them, but ever present.

The tray is slanted so it runs off back into the tank beneath, making it recirculate

 

In other countries they use tubular ones which also slant

Wow, ok, thanks for the explanation Sprink. Sounds good

Fuck yeah for coco. I started in NFT but it was a magnet for root rot, which you just don't get in coco.
Then there's the changing of the res and the filthy spreader mat with fungus gnats on it, don't miss that at all

Lol I'm probably going to regret typing this, but I've never had any of those problems. I don't use the same "tray system" that most folks seem to use though; don't know if it's that or just lucky.

One reason I haven't gone coco yet is I'm trying to work out if it's going to use more water .. What with the run off. I have to cart my water a fair way, and it's enough of a pta at the moment. Deff doing a small one next grow to see how I get on with it though.

the rot comes from mainly to high water temps over 19c and it can bloom and there is another one that can bloom if the water is to cold at sth like 15c,  ive had them both   lol  but ive had some great grows in nft   i found it best to block up the system to get more run on the tray as well  , for me when the res was on a concrete floor  worked best for me and never needed a chiller

I run channels with a separate res. I made stands for them. I've never liked the look of those nft kits. The only problem I ever have with res temps is to cold, which is easily sorted with a aquarium heater. Height of summer my res has never been over 18c.

Yep, my problem was I was using those tray kits and it was only 20 litres, and my house is warm.

I was chucking freezer blocks in there all the time. But I'd put one in before bed, and by the time I woke up, too late.

Way too much pressure

 

The only system I can imagine using now is flood & drain with coco. Damn I've wanted that for so long, but buckets, bricks & trays is much more in my price range

 

@marque08

coco hand fed run to waste will almost definitely use more water than NFT, and it can be a PITA, but I find it's more palatable making up as much as poss in one go

When I've got a big grow on, like filling a 1.2m tent, I make up 120 litres and that might last 6 days in that scenario. But then there's the benefits of no extra noise & pumps etc

yep you need cold concrete floors or a chiller   in a warm house for sure , got any pics of your  channels? so your root dont hit a res then as it separate?  as you have found you wont get rot in that system, id love to see it is there a diary?

 

id also like a flood and drain table  with coco in fabric pots recirculating, that would be my ideal set up now but i dont have the space my little cottage is tiny cant fit a tent in anywhere

The roots do make their way down to the res eventually, it's just a plastic tote that sits under the exit holes. It's exactly like the ones in the pics ( only much smaller lol. ) I have 3 chanels about a meter long, normally do 5 plants in a 2 1 2 layout. I don't really do diarys as I can never be arsed to finish them. I'll get a couple of actual pics from the shed though if you like:)
