Using Cotton Balls as a Growing Medium
« on: March 09, 2010, 07:38:06 AM »
I used cotton balls instead of grow sponges in a Classic 7 unit to grow mesclun greens. It works.
However, I learned the hard way that you must either use your finger to make a hole for your seeds or lay them on top of the cotton balls. If you try to cover your seeds, they cannot make their way out through the cotton strands.
Advantages:
- Cheap
- Easy to find
- Completely biodegradable
Disadvantages:
- No nutrients in growing medium
- Nothing acidic to bring down PH
I have been using General Hydroponics nutrients, and the greens are growing like crazy.
