More seedling transplanting. A few notes:
– the reason why they set up grow light systems on chains is so you can keep the lights just above the plants, maximizing their light. You don’t want them actually touching the plants, though, so check regularly and raise as needed.
– another alternative to self-watering trays are clay pebbles ($23 for a 10L bag at Amazon: https://smile.amazon.com/…/ref=ppx_yo_dt_b_search_asin…) — you can put them in a tray to provide drainage, and then add water to the tray, which will slowly evaporate and add moisture to the environment (not directly adding water to the roots, though, so not functioning quite the way a self-watering tray would) — these are apparently used a lot in hydroponic systems, but I haven’t tried that yet!
– the new clip-on lights seem fine, but a little less bright than I expected; we’ll see how the seedlings do. Better than they would without them, though!
