re: Feral's Journal of Insanity & Some Growing
Right so i have seen this covered before but i dont think i have shown how i setup my DWC's, i needed to setup a bucket today for veg so i took pics along the way
First up, everything you need, cheap and easy
Works out under $20au a DWC if you have all the tools and air pump
Tools:
Drill
Step Drill bit
Knife
Permanent Marker
Joint
Materials:
You will need a decent air pump if looking at any type of DWC setup, i recommend an electromagnetic pump over a fish pump any day, will cost about $50 or so but will run about 6 buckets.
A bucket, cost me about $6.50 from the hardware
Netpot lid ($7.50 hydro shop) or bucket lid with a hole cut for a netpot (6" netpots are the go)
Air stone ($3.50 hydro shop)
Air tube long enough to reach your pump (any 4-6mm tube works, im using irrigation line on this one)
19mm clear tube ($4 at the hardware for 1m from memory, probably cheaper)
19mm grommet and elbow (cheap as chips wherever)
Now my step drill bit is bigger then the hole i want to make, i use a bit of electrical tape to mask it up to the size i want, when drilling i know exactly how far to go, take it nice and easy as these bits are very quick
I mask up to 22mm, gives the grommet about 1.5mm either side of the elbow but still nice and tight.
Drill the hole in the bottom of your res, could have gone a bit lower on this one but will do the job nicely
pop in your grommet
now connect the 19mm elbow into the clear tube and then push the other side of the elbow into the grommet as far as it goes
Notice the clear tube is too long on the side, i now take my knife and cut it so it overhangs the lip on the bucket about a cm as so
Now i make 2 cuts down the clear tube, just below the lip, then i slot it up under the lip which holds the tube steady.
Connect up the air stone to the air tube and feed it from inside the bucket and up through the 19mm clear tube
Should end up with something like this which keeps the airstone right at the base of the res at all times and stops any roots from tangling around the airline etc
Its pretty much done now but a couple more things, sit your netpot lid on the bucket and use a measuring jug to fill until just touching the base of the netpot (a little over or under is fine), mine works out right around 15L.
now i go back to the clear tube and can see where the level is up to, take the permanent marker and draw a line, now you dont have to measure every time you fill the damn thing
And thats it, plug the air line into your air pump, mix up your nutes, drop a plant in and you are good to go
