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>?

I would replace the misters every month on mine.

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.

I use the yellow pope twist in misters.
