Mixed nutrients today. Last night I added 2 ml of oxy science h202 to 18L of Kamloops City water filtered through our homes water filter, no idea what it does exactly lol. I put an air stone over night and let the water bubble off any chlorine and the rest of the h202, I use microbial mass so I just wanted to sanitize the water but not kill my soil. Mixed in bases first into 21.7 C ph 8.1 Water in the morning. Important not to mix concentrated solutions, I used syringes that I rinsed well between products. I find that with this product you just follow the instructions and it’s pretty awesome results.
