Aeroponic Cannabis, a new project

Photo of what the misting looks like at 94 PSI, using 0.2 mm misting nozzles. It's really great, the mist stays suspended inside the cubes for quite a while.

I made a system like that with square buckets and misters in the lids. Pictures don’t do the misters justice.

Day 2, Growth
Today was all about adjustments. I thought the pumps were giving me 96 PSI, but it must be that when I ran the tests there was some air in the circuit. When I saw that pressure, I decided to install the two HPA pumps, but since I was missing some accessories, I couldn't install the gauges. And today, when I installed them, to my surprise, I found they were giving 160 PSI on each bank
So I turned off one pump, which I'll leave as a backup in case the other breaks, and I reattached the aluminum manifold. The result with one HPA pump was 116 PSI .
I also changed the oxygenation times because the water was heated to 24.5 Cº, and I went from 3 min/11 min to 1 min/15 min.
New misting times: 11 sec/3 min

Here's where I installed the gauges, to my surprise

And here the manifold and 1 pump at 116 PSI

That 160 looks to be more but the guage couldnt read it. Pretty set up good luck

Day 5, Growth

Room temperature: 24º/25º.
RH: 60% ~
LED power: 10k Lux.
Water oxygenation: 32 PSI ~, 1 min. / 15 min.
Misting: 116 PSI, 23 s / 3 min.
Ec: 2.1 ms
Ph: 5.8

Little by little, correcting some minor issues that arise, the 0.2 mm mistblowers are clogging, so I ordered 0.3 mm stainless steel mistblowers since they are the only ones that pull well and don't clog, maintaining decent pressure in the system. I also restarted the two pumps, one for each bench, since installing some 0.3 mm mistblowers caused the pressure to drop. Another change has been to wrap the roots in the baskets so that they wake up a little better and come out everywhere, a trick that I didn't know about and a friend recommended me to do.

Beautiful setup. Well done sir

No medium to hold the roots/plants in the cups once they get bigger?
I'd imagine they would want to tip over. Are you planning to train into a screen or net?

Hey buddy, look, this is the method I'm going to use to hold the plants. I hope it's enough.

And this is the precipitation of salts left by Athena fertilizers, nothing serious about that.

I predict that those wires will be put to the test.

Will the nozzle clog if the root grows into the space?
I will follow it , thanks for sharing🫡

I use 0.6mm nozzles and I have a 10micron filter installed before the pump. There has not yet been clogging in 2 months.

No, the root goes downwards, not to the sides.

I use 0.6mm nozzles and I have a 10micron filter installed before the pump. There has not yet been clogging in 2 months.

I did my first tests with 0.4 mm nebulizers, and the pressure was too low for my liking. So I'll stick with the 0.3 mm ones, which worked well for me in the previous crop and didn't clog. The filter I use is also a 40 micron filter before the pump.

Day 9, Growth

Room temperature: 24º/25º.
RH: 60% ~
LED power: 12k Lux.
Water oxygenation: 32 PSI ~, 1 min. / 7.5 min.
Misting: 116 PSI, 11 s / 90 s.
EC: 2.1 ms
Ph: 5.8

The roots started to grow strongly, with the first topping performed on day 8. I changed the water on day 7 and noticed that Athena leaves quite a bit of salt buildup. I didn't clean the filters, though I should have because there's more and more buildup. I'll wait until the next water change on day 14 and clean the filters thoroughly. But I think from now on, what I'll do is give them 24 hours with just water and Cleanse before changing the water to try to eliminate any residual salts left in the water. In the end, I made the stakes out of welded gardening mesh, and it was a great success. They're very sturdy and have several holes for guiding branches.

Current state of the roots.
