Heys guys

Woke up this morning checked on the babys. Can already see obvious growth with all of them.
PH was just about 6, put it back to 5.5. Were using a liquid Ph down.

We will using tap water, whats RO water sorry? Do you just mean distilled? How would you recomend it be distilled? Filtered? Boiled? Or Boiled and steam collected?

Thanks guys
