Should I elevate the three trays of seedlings closer to the T5 hood? The seedlings have been sprouted now for a month and really don't look like they've done much growing. I was under the impression that these were relatively fast cacti.
More light for Cereus peruvianus seedlings?
Yes - they should almost be touching the bulbs. Bulbs that furnish most of their light toward the blue end of the spectrum (cool white) would be best.
