MistKing water consumption - Orchid Board

Silje · #1 08-26-2013, 08:14 AM

I'm looking around for a suitable misting system for my planned, MUCH larger, greenhouse and I'm looking at the MistKing systems.

(I would of course also appreciate hearing about other brands and alternatives if you have something else to recommend)

I will need a RO system as well for the greenhouse. I have too much lime in my water and it affects my plants when the deposits get stuck on the leaves and roots.

In order to determine my needs, I'd like to know more about the water consumption of the MistKing system or other good misting systems.

Does anybody here have a good idea of how much water one nozzle use in a minute or an hour and any known time interval so that I can determine my water needs?

And does anybody here know how far apart the nozzles should be spaced for a greenhouse?

I've contacted MistKing as well and asked them the same questions, but I'd still like to hear your opinions and experiences with misting system.

If it makes a difference, keep in mind that I live in a dry and hot country and I'll probably have to run the misting system either many times per day or even continuously for longer periods of time.

Are you planning to install an evaporative cooling wall? Whether or not you have one of those might make a difference in what you'll need for misting.

I use a high pressure fog system and it provides all of the humidity and evaporative cooling for my 200 square foot greenhouse. On a summer day when it is 40degC and 20% humidity outside, to keep the greenhouse at 30degC and 60% humidity, the fog system will run nearly continuously consuming 7 gallons per hour of RO water.

My RO system was capable of producing 8 gallons per hour of RO water but I have recently increased that to 12 gallons per hour.

Hello. No, I'm not planning to install wet wall at this stage. I'm hoping that ventillation with normal fans, shade nets and open doors will be sufficient, together with the misting/fogging system.

It will be a warm to hot greenhouse. That's just something that I'll have to accept, I think and so there will be periods when the temp will rise to 30-34 degrees, but hopefully I'll be able to make those periods short and add humidity to the heat.

Thank you for this comment, David.This was really helpful and gave me a better idea of approximately how much water I will have to provide on a daily basis.

I know so little of RO systems at the moment, and I want to get something that is big enough, but at the same time not a total overkill. They cost quite a lot of money, after all. At least here in southern Africa.

I think the temps and humidity you use as reference is pretty close to my conditions as well. Perhaps even a bit lower humidity during certain times of the year, but temps into the 40s definitely.
