Small-Scale Seed Starting Experiments

It’s gray and a bit cold (low 30s) outside, but inside we’re working on seed starting / overwintering techniques with a focus on snapdragons. The tiny seeds need light to germinate and, although they thrive in cool weather, allegedly want 75 degree soil to sprout. Given the terrible germination rates last September (under lights, very wet medium) the depth of winter seemed like a good time to test other approaches.

In all, we have:

  • 3/4” soil blocks, uncovered, distant light, no heat

  • 3/4” soil blocks, covered, proximate light, no heat

  • 3/4” soil blocks, covered, distant light, heat mat

  • 2” soil blocks, covered, distant light, heat mat

  • potting soil mix, covered, distant light, heat mat

  • soil block mix, covered, distant light, heat mat

  • 3/4” soil block, outside under Agribon

Finger crossed!
