This is an excellent article. In my 40 plus years of gardening, I have experienced just about every problem you mention. I have found that the use of heat mats is critical for the proper germination of some heat loving plants. Always consult the optimal germination temperature range for the vegetable or flower to be germinated. Using a 20 row seeder with a humidity dome as you have pictured can optimize the space on a heat mat, but be careful that you don’t mix seeds that require different germination temperatures or germination times, because the humidity dome needs to come off once you see the seeds start to germinate.

A mild deficiency of P can reduce height without causing nutrient deficiency symptoms or delay in plant development. The method has been used most successfully with petunias and tomatoes, but most bedding plants are probably responsive. Fertilizers to try are those with a P analysis is 0-2%. Very little P is required to satisfy the requirements of common bedding plants. In fact, the starter charge in many soilless media seems to be enough to carry marigolds and seed geraniums to flowering with little or no effect on height.

I start all my seeds in pure compost from my piles, screened through 1/4” hardware cloth, with a sprinkle of bone meal mixed in. If snow melt here in Vermont is late and even raised beds are too wet to work, they get weekly fish emulsion to keep them vigorously growing, or even potting up for those that like warm soil. So I take care not to start seed too early since younger vigorous transplants do better than older root-bound ones.The remaining factors come into play once the mix is in use for growing seedlings and plants. High alkalinity water (i.e., water with pH >7-8 and bicarbonates above 100 mg/liter) causes growth medium pH to go up. The increase in pH can be detrimental to those species in Table 2 needing pH 5.4-5.8. Where alkaline water is a problem, growers can inject dilute acid to lower pH and counteract alkalinity. Keep in mind that alkalinity (level of bicarbonates) is more important than pH. High pH water with low alkalinity is much less a concern than water with both factors high. (Source: ag.umass.edu)
