STOP! If you have just arrived at this website looking for a hydroponic bubbler system, you might want to go back to page one of this mini-farm plan.
NOW, bubble it up!
11. Drop in the airstone bubbler, connect to the air pump, and plug it in to test for a good rolling boil of bubbles.
The bubbler with airstone stays on 24/7. This aerates the nutrient solution, keeping it from becoming stagnant, and oxygenates the root mass which will form in the bucket.
Earlier we listed the cheapest supplies we could find, to help keep the cost of this setup low. However, you might want to go to a pet shop and buy an upgrade air pump for the stone. We bought the one below for $20 and it is super quiet! Also look for a circular airstone.
air pump has two outlet ports. If you wanted to run two bubble buckets
off one air pump, run a line off each port to the two different
airstones. If you only want one bucket, then buy a “T” adapter and tie
in both ports to one airstone. No use wasting half those precious
12. Next, add a nutrient
concentrate of choice, for 3 gallons of water. If you are using GH Flora
Series (recommended), add 3 tsp. each of the Flora Grow, Flora Micro
& Flora Bloom, (one at a time, in that order). Adjust the pH of the
solution with a test kit (more on this, and ordering info, later).
