the third one down in this link http://www.freshwatersystems.com/c-500-john-guest-pp-range-white-polypropylene-fittings.aspx they aint cheap though so i hope you dont need to many:lol: for pressure switches look at grainger or mncaster carr they have any setting pressure switch youd need.

i have a shurflo that i bypassed the pressure switch on and this particular pump is rated for 150 psi and after i unhooked the pressure switch ive had the thing up to 240psi and it was still climbing so you might be surprised at what the pump can do. mine never has got hot from pumping 3 gallons...

thats the right part number for the selonoids. the 2.5 mm orifice is fine. if you went with the 40 dollars ones they use 3/8 tubing and fittings and its nothing like the 1/4 inch. 1/4 inch can be bent and curved as its very flexible but 3/8 is not and is a pain to work with. i recomend the...

are you going to have 3 containers again or just 2? id mount one selonoid right on each lid and run 1/4 inch JG tubing from your accumulator right to each selonoid and then mount your sentinal timer on the wall to fire the selonoids on the lid. if you cant mount the selonoids on the lid try and...

you can reach me with a PM

from what i have learned foggers havent performed all that well because the droplet size is to small. there is probably a thousand ways to create mist and i dont think any one of them is cheap or someone would be using it. Hp aero is more expensive but i dont think trying to invent a new way to...

you have to know the output flowrate of the nozzle and the pattern it produces to determine the proper amount and placement of the nozzles. every system will be different depending on the variables you have. the number of plants per chamber will also determine the number of nozzles needed for...

i dont use dig misters. i used those on my lp systems. the nozzels i now use put out .04 ounces per sec with approx. 50 micron droplets. the bete nozzles are good but they run about 30 dollars a piece. the dig nozzles wont work that well with 100psi as they are designed for under 80psi i...

ambient temps are around 80.

my tank has a 3/4 inch output line and my pump has a 3/8 inch line in and out. the 3/8 is pretty tipical for small diaphram type pumps. so the line from the pump i bumped up to 1/2 inch to run to the accumulator and to suck from the res. then reduced the accumulator outlet from 3/4 down to 1/2...

i dont have any chamber temp problems. my pods temps stay at 69 degrees no matter what temp the ambient room is run at. i just adjust my input solution temp to always keep my pod temps at 69. this usually means keeping the solution temp at 67. this is accomplished without a chiller. as a matter...

from grainger. its for the visualy challenged

just pick one up from most any hardware store or from grainger. get one rated to open at a little below the maxium pressure your tank can handle. or you can get an adjustable one like this http://www.grainger.com/Grainger/items/1X624?Pid=search and then just set it to the correct pressure. i...

i just mixed to a certain ec level with the dynagro. the ratio is all i was concerned with. so i just started adding to the res to get the appropriate ec i wanted since it was a one part mix. same process with the GH3 part only now you have to mix 3 different bottles to get the ratio. just mix...

i tryed the dyna gro profoliage in my hp SYSTEM AND COULDNT GET IT TO WORK. PLANTS ALWAYS LOOKED LIME GREEN AND MAG DEF. SWITCHED BACK TO gh AND THINGS TURNED NORMAL LOOKING AGAIN. WHEN I CHANGED FROM THE DYNAGRO BACK TO GH I KEPT THE INPUT EC THE SAME BUT THE FIRST DAY AFTER SWITCHING BACK TO...

anyone else having problems accessing thier control panel and pm's. the thing wont let me see my messages. been like this all day. keeps showing database error has been encountered.

without the accumulator the only thing you could do is add another selonoid to dump the line pressure back to the res as soon as you turn the pump off. this will keep the nozzles from dumping the pressure thru the misters when you turn off the pump but it will not help for the ramping up of the...

are you using an accumulator tank?
