Slow seed germination

Volvo · July 7, 2020

Have had seeds in Blocks and containers for aprox a week now and nothing on the Horizon re seed heads popping up.
Now i know they like warmth and plenty of light and allthough we dont get Frost here it has been a tad on the Cold Side.
can i expect those seeds to still pop up in the near future , persavere , or try again when warmer weather arrives ??.

A week with no bottom heat may be a bit soon.

G'day Mate and hows it going down your neck o the Woods??, my heart goes out to you all with these latest rounds .
yes one week might be a tad soon for the seeds ey , what do you use for bottom heat for your seeds??.
Due to being a tad shy of space i just pot or block and leave in among my other plantsn wait till they ar ebig enough for transplanting..

indoors they should pop in less than a week

I don't worry much til after 10 days, and even then when I re-sow, the first ones usually come up shortly thereafter.

If you can get a heat mat and a inline thermostat for it, that is the way to go. A 1020 tray size heat mat runs $12-16 USD on amazon. They are usually rated at 18watts or so. A thermostat can run $15-20. Not too many years back, I got a combo set with both for around $23.

Fresh tomato seed set at 82 degrees will start showing emerging loops inside 3 days. Then they should be removed from heat; bottom heat on tomato sprouts will make them leggy. Old seed might take longer. I use 75-85 depending on whether there are other seed types on the mat.

Most all are made in China and look something like this:

Our climates are obviously very different, I don't know your daily temperature ranges for day and night. But my volunteer tomatoes that have to sprout in the soil outdoors don't usually show up until June at the earliest, which is over 8-10 weeks after I sow them inside in the warm house (and a heat mat usually) So if your outdoor conditions are just not warm enough for tomato seeds, they won't sprout. If the days are warm enough to heat the seeds, can you at least carry the trays in overnight?
