You can get a 5 gal bucket(Dark color) , air pump(for fish tank) , 2 air stones , 2 air lines , 1 3+ inch net pot , cut a hole in the lid the size of the net pot and place net pot in hole then drill two holes near the top of the bucket for the air lines(above the water level)maybe 2-3 inches apart , attach air stones to air lines to air pump , run the air line through the 2 lil holes you drilled with the air stones in the water. Add water , turn on pump , put on lid add hydroton or rockwool or both , add clone or seedling ,put a light over and see you in 3-4 months. Ph/ec and change water/solution every 7-14 days. Good Luck hope my 2 cents helped.
Happy Growing!
