Transplanting+Seedlings+Indoors

Preparing space to transplant seedlings
Prepare enough containers to plant a few selected seedlings from each cell into a separate pot. Use the remaining seedlings for exploration and to feed to compost worms.

Transplanting seedlings
Plants are ready to transplant when they have one set of true leaves (about two weeks after plants sprout). Be sure to handle seedlings by the leaves, cotyledons, or soil plug because the stem is fragile! Avoid disturbing roots when transplanting.

Plant the seedlings, ensuring the soil line of the plug is the same as the soil line of the larger container when it is planted. Water the potting soil gently (to not damage the seedlings) and thoroughly (some water might exit the drainage holes at the bottom of the containers). This gently packs the soil around the roots and helps establish a successful transplant. Set up a water-wick system to make sure that plants remain at the proper moisture level.

Place the containers onto the grow light shelf. Ensure the lights are the proper distance from the top of the tray (no more than 2”). Ensure potting soil is moist before adding fertilizer. Add fertilizer at the amounts and times instructed by SLUG staff.

Compost excess plant material!
