Planted another large flat with a combination of later flower starts, and some additional tomatoes and herbs to bolster some weaker looking seed starts. I let one tray get a bit dried out, and those starts have really suffered as a result.
All of these starts went into a 50/50 mix with pittmoss as before. Its a really neat product that seem to be working well, the earlier flat of flowers is over 50% germinated already. Definitely helps with moisture control.
