some of the plugs that my seedlings started in have green algae is that bad. and if so what do i do get rid of the algae. what cause this problem.. thanks
yeah, algea is bad. cut off the algea if you can. try adding 5 ml. of 3% h202 (hydrogen peroxide) per gal. of water. use this to water plants. keep a fan on your seedlings to make it difficult for spores to settle. peace
