Microgreens season resumes

After the heat of summer made microgreens impossible to grow in the small greenhouse with very limited temperature controls, I've now been able to resume growing them now that fall has arrived.

I'm growing kale, sunflowers, radishes and green peas.

Because temperatures are still very high in the greenhouse, I must water three times a day, morning, afternoon and early evening, to keep them from drying out.

Temps plunge

Colder winter weather has moved in after a weekend in the 60s and 70s. The high today was 28 degrees, and the lows are in the mid 20s. The greenhouse ran out of propane last night, and the temperature inside was about 54 when I discovered the heater was out at 3:34 A.M. Even with the Mr. Heater Big Buddy propane heater on its high setting, the temperature inside only reaches 60 when it's 28 outside. At night, the heater keeps the greenhouse in the 50s. A tray for sprouting peppers is near the heater so that it can stay in the 70s to aid germination. The rest of the plants and germinated seed should fare well in the 50s. Elsewhere, rain barrels have frozen over, and icey precipitation has accumulated on the ground.

Oasis Cubes better than seed starting mix

In my comparison of using a seed starting mix and Oasis cubes for germinating seeds, I have found that the Oasis cubes far outperform the seed starting mix. Not only is damping off not an issue with the cubes, but there has been a greater success of germinating pepper and tomato seeds with the cubes. It remains to be seen if the advantage of the cubes continues on to transplantation. It may turn out that the cubes simply do not measure up to a root ball of seed starting mix when it comes to putting them out either in the garden or into hydroponic media.

Effective control of crickets

After losing successful starter seedlings to crickets, I have had to undertake a total cricket eradication program in the greenhouse. This included removing all dead leaves and debris from the floor, getting rid of clutter an extra buckets and other items that were not in use, and spraying the greenhouse floor, wall and doorway with an organic pesticide. Essentria IC3 is an organic pesticide with plant oils as its active ingredients. Although I was skeptical that the product would work as I needed it to, it turns out that after two applications I have almost totally eliminated all crickets that were already in the greenhouse and ones that migrated into it after application. I still must follow up with a light spraying daily in order to control the crickets that have entered each night through crevices and cracks between bricks in the floor of the greenhouse. But I have lost no more seedlings since I have using the product..
