Fleaz'z Grow Blog: First Grow!

[johnny108]

I grow in a semi-soilless mix with full strength triple-20 fertilizer applied every 3rd watering.
A large portion of the mix is coco coir:
10 quarts coconut coir
5 quarts perlite
5 quarts vermiculite
5 quarts commercial bagged potting soil

I used to water full strength fertilizer every other watering, but this was wasteful.

Coconut coir and (sphagnum) peat moss both retain moisture. When using coir seed starting discs, I had seeds mold due to excessive water retention (I watered too much & too often). When I added enough water to saturate my peat based seedling mix, it grows white mold. With that said, they are good ingredients for a Potting mix; but beware over watering.

To manage the mold, I sprayed a 1:1 mix of peroxide and water. No harm to the plants, just water spot damage to the leaves.
