Hi y'all, I'm 3 yrs new to gardening and just bought my first 3 tier plastic portable greenhouse. I did learn about venting just in time to kill about 50+ sprouts.... I replant my garden at least 3 times before it takes over my life. I need some advice on moss... I purchased moss from a nursery a few weeks ago. Waiting to finish a brick project before planting. However it is not doing well in the greenhouse. Lightly watering every day. It is on the second tier, and I'm leaving the top 1/2 unzipped at all times as right now we are 80degrees at night .... Zone 5/6... HELP
