I reused the soil from my last grow except for the top layer of 10cm, which I removed. The Church plants look happy and healthy.
Serious 6 germinated super fast (I used the method that Serious 6 recommended which was a game-changer for me)
I will repot the Serious 6 to the Autopots next week.
Because of high heat during my last grows especially during the summer months (day temps above 30 C) I am experimenting with A/C. Just ordered the Ecoflow Wave 2 mobile A/C unit. It can cool and heat. Let's see how that goes once it is here.
