Seeds don't pop

I just used 3% because that what I have. I soak in small clear plastic cups that are about 1/2 full. Then I’ll put anywhere from 3 drops to about 10-12 drops in. Doesn’t seem to hurt to put more. At least not for me. If you use the 6% I’d start with 5-6 drops.

Try rattling those seeds around on some sandpaper first also. That really seems to help me also. Helps moisture penetrate the seed husk. And warmth is key! MUCH higher germ rate at 85°F than at 70°F

Thanks a lot.
But this leads to another question.

How much heat can a seed take before it get killed?

I don’t know about that. Lol. I’d guess much above 90° might be an issue. I say 85 because that’s what I set my mat on. It’s usually pretty cool in our place so I’ll bet the water actually is about 80° between the ambient temp and the mat underneath. I can’t put the thermostat into the water. I’ve had same results on a cable box or a DVD player.

Where I live we’ve been dealing with 100°+ temps every day since the beginning of June and my girls go outside at about 2 weeks of age. So, while growth may be stunted a bit from the heat, they really can deal with quite a bit of heat
