My dream greenhouse

[DavidCampen]

I built my own RO system.

I have a pump that boosts the feed (tap) water to 100 psi before it goes to the RO membranes. The RO water then goes into a several gallon pressure tank. A pressure switch opens the feed water valve and starts the feed water booster pump to start RO water production when pressure in the tank drops below 30 psi and then stops RO production when the tank reaches 60 psi. When this tank is at 30 psi I get 4-5 gallons per hour across each of a pair of DOW Filmtec residential membranes (TW30-1812-75).

I have a second booster pump that takes RO water from the first (low pressure) pressure tank and boosts it to 100 psi into a 2nd (high pressure) pressure tank.

For watering, I use a hand sprayer wand:
Solo 28in. Universal Wand Assembly, Model# 4900170N | Spray Guns | Northern Tool + Equipment
The wand is connected to the RO system. I have a 3-way ball valve so that I can select either the low pressure or high pressure RO tank. I use the high pressure tank when I mist for extra humidity and the low pressure tank when I am watering. I have another 3-way ball valve so that I can also put the water through a Dosmatic dosing pump to add fertilizer solution before it goes to the wand.

For overhead mist/humidification I feed RO water to a 1000 psi pump to get an extremely fine mist/fog. I don't use an evaporative cooler so this fog system provides my humidification and evaporative cooling.

David,

Thank you very much! I have copied your post to my husband if you don't mind. I will keep everyone posted to how it works out.
