If you’re following my other journal(s) you’ve likely already seen what I’m about to cover.
I am currently in the middle of putting different amounts of holes in different designs on my solo cups for sprouting. The additional holes help alleviate over watering and I’m trying to see if the additional oxygen is beneficial. Last run I tried a few designs and this run I’m trying a few more. Here are the cups:
I filled the cups with Coast of Maines seedling starter mix called sprout island. Here’s a shot of the seedling mix:
It has a very low nutrient content which is what I prefer since I spend the first 10 days aggressively establishing myco as best as I can. One of the most effective ways of doing this is ensuring the plant has a need to make a myco connection. A plant will dedicate as much as 30% of its carb production toward myco, but it has to have a reason to spend this much energy. Once a plant realizes it needs help getting more of what it wants, it will send a signal out which will entice the myco to come over and link up. Then the magic happens.
Here’s a shot of the seedling mix a few days ago
That is 1.25 gallons of seedling mix cut with 2 cups of perlite, enough for 10 plants. The mix comes with perlite but I’ve always found commercial mixes to be lacking in perlite amounts. More oxygen in the root zone equals bigger, healthier roots and plants with more beneficial bacteria. So I cut all my mixes with perlite if they haven’t been recycled. I watered that seedling mix with 1 L of pure water with microbes mixed in. Here’s a shot of the microbes used:
I have their benefits broken down in my other journal if anyone is interested or we can chat about them here if anyone wants.
After spinning the seedling mix around to get a good mixture I set it near my radiator for 2 days to allow it to really start kicking life into gear. After 2 days of this I put the mix into the individual cups as seen here:
I just use my pinky to push a hole down to my cuticle in each cup. Once I’ve done this, I set the cups on a makeshift heating system and raise the soil temps to a minimum of 80F preferably closer to 85. Here are the cups warmed and ready:
I let those cups sit at 80-85F for 12-24 hours depending on life.
