increasing humidity , with orbit arizona misting

[palm521]

ok, there is Foggers and very expensive harwdware to increase the humidity.

i was looking for a cheaper solution, that could grow over time. upgrading it as needed.

these pictures are the results using 22 nozzles with their 80 USD 160 PSI pump. (from the professional series, costs about 30USD per kit).

the solution might not be the best.

invested so far about 230 usd. done over time. just adding more sections. i am betting that a single pump can feed around 32 - 40 nozzles. that is enough for a 25 square meters (3.5 meters tall) greenhouse.

the longer the line , the longer it takes to fully pressurize and provide the desire effect.

this system will increase my humidity from 32 % to 71% in 12min.

to make the system more effective in closed enviroment the use of fans will turn the small droplets in a medium Fog. around the area.

pictures from my angracoid area. (some other humidity loving species share the space)

Edit .
once the growing area (size) has been upgraded will look for a more "expensive solution" and professional solution . has anyone ever tried or heard about this one below?

Mainland Mart's Industrial Ultrasonic Humidifier and Evaporation Humidifier

Thanks

that setup looks more expensive than the jaybird foggers, Jaybird Manufacturing - Manufacturer of humidifing systems and fogging fans.
I used the aquafog 700 in my 12 x 24 gh and it worked very well.....with a humidistat.....check it out!

For my growing area that is about 25 square meters, on a hot summer day in arid Southern California I will run my fog system at 20 to 30 liters per hour to maintain humidity.

From the link the largest ultrasonic system will produce only 15 liters per hour, costs over $1300 and consumes what seems to be a lot of power (1500 watts). At that price I would prefer my high pressure fog system.

A wet wall will be a less expensive way to evaporate 20 to 30 liters per hour of water. I used my high pressure fog system because of architectural constraints that prohibited a wet wall.

david , what fog system are you using?

i have heard really good things about that ultrasonic fogging system, yes it is pricey, again i am open to suggestions, my greenhouse will be 4 times larger (100 square meters in about 3 months) so there is time to actually figure this out.

Thanks!

I use orbit nozzles to water my collection automatically. Works well. I have 10 nozzles lately but will add more soon. It definitely spikes my humidity but for sustained humidity I use a five head ultra sonic fogger in a plastic bin with a fan attached that forces the air and fog in to the grow tent via pipe. Works great. Also I have a himidistat controlling it from Zoro tools.

Here is some description of my high pressure fog system.

What is the ambient (outside) environment? I use the fog system along with a large exhaust fan to achieve
evaporative cooling.

For a 100 square meter greenhouse you will need either a wet wall or a high pressure fog system with large exhaust fans. The wet wall will be less expensive and can run on tap water while a fog system will want RO water.

i have 24 nozzles now , works fine, but now i need to increase air movement, as more plants are added more obstacles are in place. also , plants do get wet, if left unchecked, so more air will do the trick.

i bought a few addons to my system, one valve with a timer, and a electric cheap (15USD) timer,

my set up is all set for 8 am every 3 days, at 8, the water opens to fill the line, at 8.01 the pump starts, it works for an hour and a half, at 9:30 Am the valve shuts down the water and at 9:31 the pump stops. just to clear the water line.

i will be watching closely as the gadgets got installed today. stoping at 9:30 it gives plenty of time for the plants to dry out , just before nightfall.

David :

if there are plans or instructions about how to build a wet wall, please share. does not need to be pretty. as long as it can have the job done.

thanks

Antonio.

hi David,

temps outside are actually cooler, than it is in the greenhouse. i can get in winter around -2 celsius in some days, most of the time it gets down to 5 celsius.

during spring, temps are more in the 10-14C at night, and up to 22 day. humidity is extremely low. also there is no clouds, and the sun heats my greenhouse up to 37 Celsius, 5 minutes using my system can bring my temps to 26-27 .

summer in here, is actually rain season, and temps are usually lower, due to the lack of sun. i can have RH of 95% during this time of the year, as i can get non stop rains for 2-3 days , stops for 12 hrs and then it rains again. (RH can stay up to 75% for several hours , then it goes back to 40s by nightfall.

right now i have the system delivers water every 2 days at 8am up to 9:30am, by end of day the plants are all dry. the mounted plants (angracoids) do appreciate this. depending on how this goes, i plan to water with the hose on saturdays.

i am just experimenting with this, but concern about how much i am going to need when the greenhouse is expanded.

thanks for the links, will be reading them tonight!

Antonio.
