Starting on the cheapHello may i ask why you dont use a pre buffered coco like canna coco makes life so much easyer and you know it has been washed and buffered properly and saves a lot of guessing and headache's and you dont get ph swings
apparently I have already spent to much according to the Mrs it's like $16 for 90l of Coco apparently it's been used before without issue from other forums I have read, I just washed and buffered as a precaution so hopefully it's not an issue, I hope the Coco gives a much higher yield as feeding Every day is so much more excessive then soil and hard to fit into a busy schedule
