I was about a bunch of new pots ordered me (was my last order 2012), when I read the reviews by reading me: Now I'm super glad that I took the advice of a friend on the internet and my potting soil (Romberg) under mixed vermiculite. (Have now added myself also perlite to test the difference). With the help of V. the moisture in the soil is perfectly captured. I have found NO mold. And --How photos zeigen-- I even worked with extreme humidity in the greenhouse .. up to 30 ° C, it was at the Chilli sowing initially - until I had to trick out and special width Ventilation slots on 28 ° C came. The cover was a few days (it germinated surprisingly fast !!) very fogged by humidity and heat, so I often aired, that is, the lid for a few seconds decreased. Sowing was on 01/28/15, early peppers germinated already at 4.2. and now are the pepper seedlings in their biodegradable pots as well. Soon the 2nd sheet series is form, so I'll put them into larger pots. I highly recommend these pots if you want to sow in a small space and are not transplant. That I can later implement the seedling cultivation pot together into a larger planter, is awesome.
