That is a beast of a PC! I’ve got an all American 27qt and love it. Mix your old substrates into your soil, its amazing. And your flushing blocks produce tons of co2, great to have them flush on a shelf in your tent for that co2 boost, especially since mushrooms need o2 to fruit.
Also Veg room update, everyone looking happy and healthy. Also started some Purple Hindu Kush bag seed i had laying around. BodhiTree bagseed (mostly) starting from the right in the picture.
I rock the pre malted stuff from the brew shop. Brewers are trying to max out similar enzymes with malt. If you research it, we really cannot match what these large scale “maltsters” are doing at our home. They are using way more science, not to mention it is one of the oldest trades around.
