Like diapers for babies, it seems like there is no end to the doo-dads and supplies one needs when starting seeds indoors.
My brassica seeds rocketed into sproutdom WAY faster than I imagined they might and I was caught without a means for transplanting the soil blocks to a larger size. I cant really afford to get the larger soil blocker and I didnt have any larger containers right away so I figured I could use an excess diaper box to jury-rig something to transplant the seedlings into.
I was exhausted by the end of this DIY project because I could not find my exacto-knife (DH put it somewhere “safe” and now lost) so I used a pair of KID scissors.. use the knife.
The main hack here is to cut skinny rectangles and then some slots so that they for a grid that fits in the black tray.
