I started like most, buying distilled water from the supermarket and lugging it to my place. I got sick of that quickly and bought a distiller to stop all of the lugging around. This was definitely an improvement as I could just add tap water to the machine and 4 hours later I would have a gallon of perfect distilled water.
While this was an improvement, the cost of the electricity and time made it seem less and less of a great idea. I did this for months until I started to look into RO systems. When I first looked at them I saw many in the neighborhood of $300 and that was way too much to spend for a part time grower.
Then I found it, insert inspirational music… ahhhhh
AQUATICLIFE Aquatic Life RO Buddie Plus DI Four Stage Reverse Osmosis Deionization Unit 50 GPD
It is only $59.99 and can produce 1,500 gallons of perfect water. That works out to $.04 per gallon. Score! No brainer and was VERY easy to set up. Did I mention it only takes 30 min to make a gallon instead of 4 hours with zero increase in electricity, win win win
