I am new to the Tower Garden. As suggested, I only used half the solution of tonic for my seedlings. My reservoir is now half empty. I plan on filling it up, my question is, when I fill it up, should I add another 200ml of both tonic a and b? That should bring it to the full solution, right?
Hi firstname.lastname@example.org, An easy rule of thumb is after seedlings are >= 4weeks old, move to full strength. So if your TG tub is half full (~10 gallons) then you would add 10 gallons of water and 200ml each of TG Mineral Blend A & B.
