They should be just fine and you can always give them a little fish fertilizer at one tenth dose at day 8 and add in some Thrive B1 around day 10 to help heal roots from any nicks when transplanting, important step give it a try along with a smidge of fish and have pot partial damp and earthbox should be ready now - - backfill hole around an empty rootmaker in place in soil and mist soil even if damp and then pull empty and insert transplant and gently press into place, no backfilling required and no water required but mist top if you like but lightly, really no water everything is already damp and set - monitor several times daily at first but then all should be well .... slow, understand you’ve transplanted 1,000 but I wanted to share whats been working And share the empty backfill as some will dig big hole, insert plant and then backfill - no no no - put empty pot into hole and backfill and moisten soil and then pull and transplant - works like magic every time!
Peace,
