misters for an aeroponics unit

i am going to build my own aeroponics unit i was just wondering if anyone has any ideas on where the hell i can get some decent misters from ?

i have planned everything out using a few different guides i found on the internet and i can find everything i need except that i can only find really shitty mist heads. can anyone help me with this ?

the other one is that if i am building an aeroponics unit i was going to have drainage in the bottom to allow for any excess water to escape back into the water tank would this be ok or do some of the roots need to be submerged ?

any help would be appreciated as well as any tips to aid my design

thanks muchly

The misters are a key part. That's the weak link in an aero system. You must fix/clean the misters regularly, so if you have bad ones to start with...

Of course you have to have a channel for the misted nutes to flow back to the res. There will be quite a flow of water, and a lot of roots. The roots will fill the space and clog up the flow. It's OK for roots to be submerged if the water is aerated enough, and in an aero drainage system, that's where the roots will want to go.

Also, your nutrients and the pH will have to be closely monitored, because as pH shifts, and dissolved solids precipitate, the crust forms on the misters, clogging them up.

You are trying a very advanced method of hydro. Let us know how it goes.

when we do the build we will wack it on the site as a guide because the unit we are going to build should be fairly good.

any ideas on how much the nutes will shift up/down and which way ?

thanks

I had a problem with misters before too. I realized that I bought misters for high pressure appliciations. Only a very little water came out. I switched to low pressure and everything went smooth. Maybe that is the problem>?

The best sprayers out there! MRSD300 Drill them out to 5/64ths to make them really shine! Also placing your pump into a 300 Micron Filter Media Bag will keep everything running perfect! No maintence as well as no clogs ever! If you have to replace then your not doing it right guys!

The key to success in aero is high volume low pressure not high pressure low volume! Enough said.

After a while I gave up on the misters. I used a pvc pipe that ran through my enclosure. I drilled 1/8" or smaller holes pointing up and the water sprayed the lid and bounced back and hit all the roots. Didnt really have any problems with clogged jets anymore after that.

How many misters can be supplied with a 396 GPH pump? and would a pump filter bag filter out the nutrients also? not allowing them to get to the plant?

Whatever you do, don't waste your money on these clog-o-matic sprinklers from Raindrip that you commonly find at Home Depot, Lowes, etc.

Ha, ha your either trying to be funny or just inexperienced and backwards. Intermittent medium (15 to 35 psi) or high pressure (35 psi to 80psi) low flow both easily out perform low pressure high flow. Low pressure high flow system have never performed very well, especially with low pressure high volume pumps. Then there are the really *hitty low pressure high flow sytems where water is run 24/7. Nearly all low pressure high flow small tube aero systems have root rot and or Pythium problems. Almost every small tube low pressure aero sytems root photos I have seen posted here and on CC sure show a lot of brown roots. Healthy roots are white.

The people typically complain about the sprayers such as above are the ones using low pressure high volume pumps. If you ever ran what you call "low pressure" sprayers with adequate water pressure you would see they all work well. The ones that actually work best are the ones that do not work well with the cheap low pressure high volume pumps used by most novice and or cheap growers. Simply use a pump capable of pumping over 15 psi and all the "low pressure" sprayers work well, even the Raindrip sprayers as sold at HomeDepot and Lowes etc. If yiu would bother to check you would find that "low pressure " sprayers are made to operate at 15 to 30 psi. None of the low pressure high volume (flow biased) pumps deliver water at pressures that high. That is why the do not put out a good spray. Just consider ecah and every spray head causes what is called head pressure. If the pump your looking at does not pump to a maximum head in feet of at least 25 feet it is not really worth buying for aero use.

ie Use a pressure biased pump not a flow biased pump.

Here is a good small pressure biased pump. It will outperform any low pressure high volume pump as it provides up to 24 psi.
