I have found the magic of the coco products through raising citrus,
I was planning on starting my tomato seeds this year in 1/2 potting, 1/2 cocopeat this year.
My seeds just didnt do well last year, so if they dont take off like mad, ill eat my pride early and buy starts. I didnt give up till June and it was already too too hot to happily plant out starts
Good luck starting!
