If you use a heating pad for starting seeds, you need to keep a watch at the temperature of the soil. I measured over 90F in the center of the tray and over 84F at the corners. This is with the plastic dome on and the shop lights switched on. I used a “instant read” type meat thermometer from the kitchen drawers 😉
Of course this temperature is too hot and this is probably why my impatiens seeds are not germinating.

Looks like it is going to be last last year again. 🙁
Well it has been 20 days since I planted a batch of seeds. It has the bottom heater, lights, dome, everything they need……….still out of the the 72 “coins” nothing has sprouted….not even one! I guess I should check the temperature with a thermometer. I bet they are too warm.
check out an update which I posted later
Planted these annuals today:
- Shasta Daisy [10-20 days]
- Snapdragon [7-30 days]
- Petunia Horizon Yellow [7-21 days]
- Petunia Dolcissima Fragolino [7-21 days]
- Petunia Wave Hybrid [7-21 days]
These were planted peat ‘coins’ and with a heater mat under them. The whole thing is a Jiffy greenhouse pro.
So yesterday night, I started planting some of the seeds. I know it is a little too late now. The frost date in my area is around the end of April. Here is a quick online tool to find out your frost date. So from today we have around 7 weeks left. I have planted:
- Petunia Shock wave Red [7-21 days]
- Impatiens Accent White Hybrid
- Impatiens pink [seeds harvested from our neighbor]
- Impatiens Shady Lady Tango [orange]
- Impatiens Accent Red Hybrid
- Pentas New Look Mix
They say that we should start them 8-10 weeks before last frost. Hence should have planted around Feb 15th. These seeds were bought from Park Seed.
