>>2716390no issues, just that my soil blocks don't get it other than seedlings like flowers that stay in the mini blocks for a while. For me, algae is being too wet, but don't have the issue with soil blocks. Here is a pic from two years ago at the growth between the two, both started at the same time, under the same conditions. There are marigold. only difference was left was soil block with soil block mixture and right was regular plug tray mix
