I put a small glass of water next to my laptop fan, give it a couple of hours to get to a nice temp, drop the seed in, then within minutes of it sinking naturally (not poking it a round the glass Lol), I plant it root facing up in the soil, around half an inch down. Then wait, always pops within 3 days. If it can't turn itself, it wasn't worth growing anyway! Lol
If soil is too cold, I wrap it up in tin foil, then you see a bump in the top of the foil when she pops.
Too many people mess around with aloe vera lemon flavoured scented, skin frienldly premium tissue, and all that bollocks! Yes you are playing nature by controlling the environment of your plant, but don't mess with the nature of the seed itself. Just does more harm than good!
