About every two weeks or so change your water and nutrients. As your plant gets bigger you may need to check the water level more often.
Ok, let's see how much it cost to build this system at the time that I wrote this guide.
The Bucket and lid cost $0.00 it was free.
Air pump from Department Store $6.67
Airstone from Department Store 4 pack for $3.49 $0.87ea.
3.75” Net Pot from Online Hydroponic Store $8.99 for 12 packs that equal $0.75ea.
Air tubing from Department Store $1.99
Growing Medium $0.00 Free from my driveway.
Everything total was $21.24 because I had to buy parts in bulk. If you break down the cost to build one system:
Grand Total To Build one system was $10.28
The total time to build this system was less than 30 minutes.
This same system would easily cost you anywhere between $30.00 to $70.00 if you bought it from a store. Even if you bought it on an Auction site it would run you $25.00 or More and that is not even
