Hello everyone! In the past I have used the paper towel method in a ceramic bowl, over a ceramic plate, on top of my water heater tank. This method worked very well, at about 90% germination rate. This year, I am living in a new place, no water heater tank and no ceramic bowl! So I have tried several new methods: jiffy seed starter greenhouse - in the window jiffy seed starter greenhouse - in the window under a warming mat from sunleaves paper towel in Tupperware container - on warming mat, under towel All three were given 7 days. The jiffy greenhouse in the window without the heating mat, had only 1 out of 5 show any sort of taproot, but never grew further. The jiffy greenhouse in the window with the heating mat, had only 0 out of 5 show any sort of taproot, but never grew further. The Tupperware/paper towel/heating mat had 4 out of 5 crack, and only 2 grow to seedling. The variables here are: Temperature, water, PH, light, and oxygen/nitrogen/co2 I was thinking that my methods used previously, with the ceramic bowl and plate, worked well because it was not air tight, yet still kept in moisture allowing a small amount of fresh air. and it was at a optimum temperature (temperature not measured) tap water was used (results suggest proper PH) So what does everyone think? have you had success with sealed containers(Tupperware)? whats the optimum temperature?
