ive got some green stuff appearing on my compost grow bags in my greenhouse, am I over watering or is there not enough air getting in
algae. you may be over watering, algae like wet
Use a penknife to stab a few more holes along the bottom edge of the growbag. They often don't have sufficient drainage.
Ok great thank you, will it go on its own accord or do I need to scrap the algae off?
