airstones and pumps can be purchased at any Hydro shop or you can pay about 1/3 of what they charge and go to fish department in Walmart :thumbsup: 2 stones, line and get the dual outlet air pump. Duel outlet costs just a bit more but you will get more O2 into the water (bubbles) and the plants will thank you greatly!! If there are no construction sites around you can get the 5 gal bucket at Lowes, they are already light proof and run about $2.50. Thats one thing that wasn't mentioned, NO light to the roots!! Bucket and lid MUST be light proof. If you have a couple extra bucks go to petco and get the black air tubing instead of clear. Put a couple pics in, the last is of a rootball.
