Hi friendly friends Ive also made a cheap little system, for basicaly under 50$ total
Tools and Equipment:
Scisors
Knife
baby bottle nipples
air pump
airline (hose for pump)
Air stone
extention cord
rubbermaid tub (1'x6"x5"(LxWxH))
Spraypaint
Method:
1) the rubbermaid I got was see through so i used a green spraypaint i had lying around to paint over it and cover everything and make it generaly opaque. You cant see it in any pictures but i also left a little window so i can peep in on the water levels and see how the roots are doing (and marked danger levels with a marker). In the lid to the tupperware I cut (honestly i didnt have good enough knife to do the job so i resulted to melting it open) then sprayed over everything

I would reccomend doing more than one hole at a time but im a glutton for punishment and have only done one
2) After all the paint dried I stuck the nipples in the hole. With the nipples though i cut the end nub off pictured:

through this hole you will later put your cutting, into your aqueous solution.
3)unpack your air** stuff:

then put it all together and into the bottom of your bucket:

And fill it with water, and thats pretty much done.
I would reccomend drilling or carving a little divot or hole to poke your air tube through so it wont kink aswell as an extra hole for pouring water in, so as to not disturb your roots too much.
4)thats pretty much it just pop your cutting in, and viola you are done,


later improvemtns will be a stabalizing system for when the cutting gets bigger, i dunno how it will do mabey just a makeshift cage or something to keep it upright. Also dont kno what im going to do when it outgrows its box, let allone the rootmass gets too big for the hole. what eves!
