First Greenhouse 2019

~UPDATED 5/7/19~ It's been a cold long couple weeks here, I have the greenhouse all buttoned up but heat is still pretty low, I'm lucky if my temperatures break 22C during the peak of the day. I also have have some time to start regretting my choose in seedling soil this year, the Roots Organic Micro-Greens seedling mix probably shouldn't have been used in the 10cm x 10cm pots I have currently, if I could go back in time I would have either stuck with my old stand by of Nectar For the Gods #4 soil which has worked very well in the past or gone with what @Gugne is working with which is a heavy blend of worm castings for nutrients and coco for aeration, the results speak for themselves. As a whole I have seen a slowing in growth this week probably due to temps and lack of nutrition so to combat this I have begun adding pretty heavy doses of pure worm casting tea, this is an EC of 1.55 from RO water that starts at 0.04 EC, this is sucked in from the bottom to avoid any damage to the little guys (GSC and Sundae Driver) but still feed the ones with the roots just starting to pop out at the bottom. Heating is not in my game plan though, being that where I am located should be pretty moderate-hot temps this time of year I did not expect this cool weather we have been seeing so not heating systems where put in place, I'll just be happy when its over. Watering has been another issue with the Micro-Greens I have not gotten a great handle on, you can see the algae and mold growing on the Orange Daiquiri and Wedding cake pots, this is pretty normal when your over saturating, that along with drooping leaves and poor root development tells me all I need to know so those are currently drying out. On the other hand my watering for the others has been really good and accurate, good root development already showing through and nice upright growth with minimal signs of stress. They do all have a paleness from lack of nutrition but I am working on that. Gadgets, lets talk about the weird silver mushroom thing with all of the wires. that is actually a temporary install of my DIY aspirated air monitor. It works by shielding the temp probe (and eventually humidity) from direct sunlight and moisture, it also has a fan that constantly pulls air through for the most accurate temps possible. The temperature monitor actually controls the misters which do a good job at dropping temps, but produce too much water, I will be changing to an evaporative fan unit for temps and moving the misters to humidity only but that is down the line. For now this has dramatically improved my environmental monitoring ability. Final notes for the day, the GSC still suck, but #1 is showing promise so its a good thing I only need (1) in the end. My Sundae Drivers are also out, and one of them died before it even opened its cotyledons, that was sad but again #1 to the rescue, it is looking good and in a few days I will have a better idea. For now I will go forward with boosting my worm population, and I think I have a good idea on how to do that rapidly with some avocados and a crazy idea from Colorado, I'll post some results once I give it a try.
