Tracking info just came in on the Eco and its supposed to be here by Friday the 3rd. :/ Later than I was hoping, hopefully it gets here earlier! It's coming via ups and is in California right now. What do I do if the plants get here before the substrate?
I would throw them into a bucket with a fish tank light or planted tank/or daylight bulb. I usually use pwc tank water, so it has some stuff for the plants in it.
Love your light bulb creation.
