I have the same situation. I'm going to transplant from cups to 15inch @top/12inch@bottom potters. I'm just using Fox Farm Ocean Forest to mix with the starter mix. After transplant is when I'll start nute schedule to adjust accordingly.:hippy:
FourTwenty4Life Reviewed by FourTwenty4Life on . trying to save seedling starter soil... is there anything that I can add to a seedling starter mix that would make it suitable for when I transplant to a pot? I have a lot of leftover mix that I'm never going to use so I figured I might as well try to save myself some money. I was thinking maybe some more perlite plus worm castings or bat guano (I'm not using any other fertilizer)... Rating: 5
