starting japanese maple seeds
I've been starting JM and bamboo seeds indoors, using heatmat and grow light. My JM seedlng get about 1 or 2 inches tall then turn brown and die. They are in humidity domes,watered from the bottom. Temp. set at 70, with light on 8 hrs. Are they getting to much water, or light? Trays are sprayed with captan, so it doesn't look like dampning off is the problem. Bamboo seeds grow fine. Could someone give me am idea of what I could be doing wrong. Thanks.
