I always start mine the last week of January in 'waves'. I use the older heating pads that don't have the auto cut off and a heat mat thermostat called Jump Start. You plug the heating pad into the Jump Start and stick a probe into your seed starting medium and set the thermostat to the temperature you want. Worked great last year. Previously I was using glass encased photo thermometers which required constant checking.

If anyone has any germination information for starting the Voodoo Flame Ginger - Burbidgea schizocheila I'd appreciate it .. seeds are tiny. Don't know if they need light, darkness or they don't care.
Here's my list so far .. I'll be adding a lot more to the list in the weeks to come .. I'll be using GA - gibberellic acid, a plant growth hormone on the Canary Bird Vine since they are very difficult with poor germination rates to get going.

Blue Honeywort - Cerinthe major subsp. Purpurascens
Brazilian Coral Tree - Erythrina crista-galli
Calendula - Flashback Mix - Calendula officinalis
