i didn't really go into detail, no, but i will, and after trial and error the first time around, i have learnt how silly easy it is to get running.
parts: (for a simple single grow run, add multiply for perpetual)
- 40L tote (£8 from sainbury's, just make sure it is a good thickness so that it won't change shape from the water pressure) this was the only convenient size for me, as had to fit in my cab, but a shalower tote is always a good thing so you don't use as many nutruents per filling (mine will use 120ml of nutes a week plus boosts etc)
- Roll of Silver tape. grabbed thius from my store but can be had online i guess. get a wider tape, less work
- Air pump stones and tube. i am having some great results using tetra150 air pumps. they're quiet and very cheap and easy to find. £15 each on ebay. as to stones, i just bought a pair of round stones per tote, but you can just grab a pair of 12" airstones from ebay for a coulpe of quid. tubung is 1/8" diameter black hose, again, just a quid.
- net pots, hydroton clay pebbles, tray of rockwool cubes, nutes.
- a hole cutting device
i simnply did the following:-
1. Tape up the outsidfe, underside of tote. that's that done.
2. use drill or whatnot to cut out the holes for your net pots (i've opted for 4 for my size tote, and i used a drill to cut tracer holes then just hack the fuckers out with a stanley knife
3. tape over top of lid
4. drill 2 holes in side of tote for air line to go through, attatch hose and pump and stones together.
note: make sure to wash your hose and stones just to make sure there are no contaminants
done
you then just pre-soak your rockwool, rinse your clay pebbles, fil ya pot up, shove your cutting in, and leave it. you need to moniter the water level and bubble level to make sure the rockwool is wet but not soaking etc, then once the roots hit the water i added a small dose of nutrients, albeit the wrong ones.
as i say, it's a little work on your first run, but once you've got the first done you'll realise how easy the whole system seems to be. to move 4 plants from vegging into flowering i literally took the lid off and put it ontop of a tote all ready with flowering feed. then other tote just get's emptied straight outta the window. i've still got my soil and coco and root balls from fecking 9 months ago sitting in my cu7pboard!
