Where has this been?!
Normally I buy Ei kits but I see this recently and couldn’t believe it. This is a remarkable dosing system for creating a DIY equivalent of premade liquids at a fraction of the cost. Made my first batch this week and pleasantly surprised. Why nobody else does this is beyond me, also excellent write up made it super easy. 10 out of 10!
