Having a need to pH your water out of the tap?

A 5 gallon water bottle makes for a handy reservoir.

Alls it needs are 1/2 gallon increments marked along the side. ie...pour water in a half gallon at a time, when the movement of the water settles, mark a line and designate the amount.

After tons of shopping, browsing, looking, brain storming etc...there is much about a good grow that the grower shouldn't want to 'go cheap' on. Bulbs, ballasts, pH/tds meters and automated systems to name a but a few. Saving money on items less critical than grow light set-ups, carbon filters, good nutrients, CO2 and such...means having more money available to purchase things a grower ought not be frugal about. (who wouldn't spend the extra money on a more comfy toilet paper eh) Rating: 5
