Germination Temperature Matters Most

Why warmth decides how fast a seed cracks.

Germination speed with autoflower seeds depends more on temperature than on the method, and a seed at eighteen degrees can take five days while the same one at twenty five pops overnight. I use a paper towel in a sandwich bag on top of the router, which is the warmest spot in my flat. A comparison of paper towel, glass of water, and direct sowing at three temperatures is posted on https://turboautoflowerseeds.com, and warmth won regardless of method. Old seeds benefit from the extra heat most.
