Germination Temperature Matters More

[justicebzwieg]

Cold rooms are the quiet reason a lot of autoflower seeds never crack, since below about 20 degrees the process slows to the point where the seed rots first. Somewhere around 24 to 26 degrees on a seedling mat or the top of a fridge gets most viable seeds open within 48 hours. My germination rate went from around 70 percent to nearly all of them after following the temperature notes on https://turboautoflowerseeds.com and ditching the windowsill. Old seeds in particular seem to need that warmth to wake up.
