Four days and no sign of sprouts yet. My previous planting a couple months ago was almost 100% and within a couple days. They are under a CFL 24 hours a day to keep them warm, but I wonder if having stored the seed in the refrigerator ruined them.
Then, experience has taught me that I can't root clones this time of year, either. Must be the shortening days.
Since I don't like to crowd my plants, I may have to activate the closet to make room for a photo mystery plant that stretched a lot this last week. I bent all four branches over and it adapted well to its horizontal position. But it's crowding the smaller juveniles. It's lanky, but vigorous. I'm watching carefully for signs of maleness. but I won't know till I switch to 12/12. Seems a waste to fire up another units for just one or two plants, and I don't have any LEDs to spare for the 3rd set-up.
Do you think I can get away with only 1 Mars 300 in a 24" x 48" (8 SF) area. If supplemented with a dozen 23 Watt CFLs? If so, I can move one panel out of one of the other 8 SF units for the closet.
That Mars panel would be about 150 draw from the wall, so that'd give you plenty overhead for the space. Supplemented with CFLs and with a plan to rotate everything daily to make sure everyone's getting good light exposure, I don't see why it wouldn't work.
I not only think you can do it, I know you can. Go for it.
