You can remove the humidity domes today or leave them on for another day if you plants are in a room that is very dry. Turn on your grow light.
The seeds should have germinated by now and be ready to begin photosynthesis. Keep the light on for as many hours a day as you can.
Take a minute to observe your experiment and make notes in your journal. If the coco coir and plants looks dry, spray them just a bit with water.
Keep your notes simple and use clear facts.
Record what you can feel, see and smell. Note any changes since yesterday.
The coco coir is still moist. The tiny yellow leaves are are bigger than yesterday. The root is still white and fuzzy and now it has gone into the coco coir.
The humidity domes can be washed and put aside until your next experiment.
