Microgreens sprouted, steamed

My six trial microgreens trays have now sprouted. I have left the clear tops in place for two days in a row now that they're in the greenhouse, and this has been a mistake. Temps inside the trays rise high enough to steam the greens.

So far, they have all survived. I will need to leave the tops off a little from the trays so that heat does not build up in them.

I hope that their flavor has not been altered by the excessive heat, as heat makes greens taste bitter.

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..

More hydroponic melons started

Bato buckets of melon starts. Today, I sowed Israeli melons in 10 more Bato buckets. Unlike my previous starts in Oasis cubes, I directly sowed the seed into the medium in the buckets. The medium is composed of about half and half perlite and coconut coir. I've placed the buckets in the greenhouse to keep them warm, as nights are still chilly in the 50s. In the greenhouse, lows stay in the upper 60s, so the melons should germinate faster. If the starts are successful, then I should harvest melons from these buckets about two weeks earlier than melons sown directly in the field at the first of April. As for the melons started in February, they're growing slowly after having dehydrated. I was unaware of how dry perlite can be, and when I transplanted the seedlings into the perlite, I did not water the buckets thoroughly enough. They are recovering, but I think I've lost some of their potential advantage. Melons started in early February in Oasis cubes, transpl
