DWC Greenhouse update

Arizona deep water culture greenhouse up date

Here are a few pic of the greenhouse. They got too big about a month ago. Had to take out the vegetables ran out of room LOL. Everything going well so far as you can see, growing in the valley is not imposable, Take care.

Very nice!

Wow I am amazed how are you dealing with water temps ?? Using a chiller or does your DWC water just stay hot?

If you keep your grass nice and green around the greenhouse your water should stay 80 deg or so. The roots are nice and white and take up about 5/8 of a 5 gal bucket

Is that a cooler hooked up to the greenhouse? What size?

I bet you wish you would have gone with that 10x12 instead of the smaller one!!

Looks nice and packed!!

Amazing you don't get pythium even at 80f res temps. Do you run a lot of H2O2? How often do you change nutes, what size air pump and is it a recirc system? I don't see any lines anywhere... either way congrats, that bad boy is truly overgrown!

The cooler is 2000 cfm works great for the size of room great air flow. You can control humidity by turning on the pump when needed. Watch out that you don’t get the humidity to high or you will get mold. All the piping for the system is underground this will help cool the water temp in the reservoir nice and cool. No h2o2 added at all. Nutes change every two weeks works well for me. This is all tap water with a ppm of 650 GH nutes with hard water Micro. With a tap water ppm that high I run at 1300 ppm. Air pump 45 liter. You just need to think out of the box and try something new. It has been great to stay away from the high electric bill and the smell

Sounds cool. Do you have pics of everything when you were burying it?

Oh it's one of these things? and you shut the water pump off manually if the RH gets too high? or you have it on a humidistat? I'm struggling to get my humidity UP with AC in a tent... swamp cooler is probably perfect for AZ. Still don't see how you keep the res temps down though.

Yes that is the cooler i manually turn on the pump.If you can see my res,piping and buckets are in the ground. The water in the ground keeps my temp right @ 80 deg even when its 112 deg outside. Hope this helps

How often do you change out rez?

If you dont ever encounter any slime or diseases in your res then you dont need to change out just add back, not the way I would do it but yeah some people never clean/change out the res just add back water..Even 80 degrees would scare me but I guess it works for him and his operation.
