I went to the grocery store and they sell this 2.5 gallon jug of distilled water for $2.79
I bought a few and had a bunch of seedlings, more than I had planned for, I converted empties to small bubblers they work great and you use about 1.75 gallons each week when you change out your nutes...I use ROwater now
but, when I did my cloning experiment, I looked over in the corner and they were all laying around, I decided to use them for vegging and transfer them to the bigger units for flower...
