Last spring I had very low [~40-50%] germination with my yellow squash & Zucchini and cucumber success was not much better. I had to replant several times. I had ordered seeds from Gurney's.... same as other years, never had this bad luck planting these type seeds.

The control group (no method) had a 36% germination rate over 6 weeks. We took temps from jan-march on 2010 and averaged the lows and highs. Seeds were planted in a petri dish with miracle grow soil. 10hr cycle in the germination "fridge" with 70 as high temp and 45 as low temp. Day cycle ran a light inside. Baptisia sphaerocarpa (wild yellow indigo) was the plant I used. Very hard seed coat. Pods were bean like thag held seeds.
Usually 1-3 seeds would crack each time I scarified them.
