Starting seeds in Greenhouse (Non-heated)

10 years ago

I have build HFGH (6'x8') last fall, it has no fan, no heating. I wish to use this GH to start seeds early. Could you please advise us on following points;

1. WHEN TO START (as it is non-heated), if heating required for jump start, I have one small fan-heater from HF.

2. POTTING MIX- which is best potting mix/seed starting media;

3. CONTAINERS- what kind plant containers suited, should we use flats or large container for initial stages or small pots for individual seeding?

4. GH Floor, should I directly seed on the greenhouse floor (either side of the wall) see pictures;
