20 yrs in Phx. Blazing heat! Casa Grande not as bad, but still hot. Thanks for the great thread👍

Great thread

Expensive grow in that AZ heat!
It can be if you're using AC. Electric bills get crazy in the summer. Those swamp coolers only use a tiny bit of energy, however. The trade off is less fine control and a bit higher temperature range (80s rather than 60s-70s).

Found some great patents on swamp coolers that blow away what's on the market now. That's probably why they are not on the market!

The absolute max you can do with single stage evaporative cooling is a 40°f temperature drop from ambient.

As humidity rises, this max temp drop decreases. On a 70% humidity day, you'll get maybe a 10°-15° drop...

With some 'Rube Goldberging', you might be able to dehumidify the cooled air and run it through additional evaporative stages, but as temperatures drop there's a diminishing return on cooling ability. You're looking at just a tiny bit more cooling power with a HUGE hit to CFM.

In the first link, the inventor claims that the water gets down to 33F. That's cold enough for a nice indirect cooler.

Ambient temps are obviously very important. Unfortunately, that patent doesn't specify. I studied both patents and they really focus on operation in high humidity areas. High humidity is not really an issue in Casa Grande, except maybe during monsoon season. If your into DIY, you might consider a solar powered desiccant based system for making ice and using the ice for indirect cooling. This one is Ammonia/Water: Solar Ice Maker Chills with Heat

So, the 2 looking limee are starting to green up again (ignore the other stuff, that's clone stress damage).

20220806 200206


I'm going to do some defoliation as well. It's gonna get crowded in here:

Before defoliation:

20220806 200228



After:
20220806 204921


I took all leaves growing inwards, any big upper leaves blocking lower bud sites, leaves & tiny branches that aren't in the canopy zone, and anything with lingering cloning damage:
20220806 205016


I try to leave bigger leaves on the backsides of the plants and at the bottom of the canopy zone:
20220806 205155
20220806 205208


Feels alot less crowded in there now. :-D

Looks like they are improving:
20220807 200225
20220807 200230



I gave everyone another 20 oz of the nutrient mix (60 oz total, almost 1/2 gal).. and dropped the pH to ~6.6

The plants I have outside are doing well. We've had great outdoor weather, with a 107°f day in there. The plants are doing just fine with the heat. On a hot day during the heat of the day, I'll mist them a bit and cool off their pots.

I'll get some pictures up soon.

As promised, pictures! Here's the outdoor crop:

20220808 095751
20220808 095804
20220808 095814



Considering we've been getting some 100°+ days, they are looking awesome!

Watched some Kyle Kushman vids and did a bit of super-cropping & Kushman Chiropracy.. and the canopy is looking... decent:
20220811 213747
20220811 213822
20220811 213831


That will be the last of any major stressful manipulations... now it will just be removing and 'suckers' and periodic fan-leaf removal.

And yes, those are flowers forming!

Feedin Time!!

This week I'm mixing up a 4 gallon batch, and then I'll be adding 2 more gallons of RO water to dilute it. My ppm/ec meter arrives on Wednesday, but I should be ok without it for a bit longer.

I am also adding in some calmag.
20220812 202524

General Hydro's Basic "Medium Feed" schedual: https://generalhydroponics.com/wp-c...Series_FeedCharts_USD_02_GrowthStageBasic.pdf


Week #2 of Flower, for 4 gallons:
CalMag: 4 × 6 = 24 ml (6 gal dose)
Micro: 6.1 × 4 = 24.4 ml
Gro: 5.3 × 4 = 21.2 ml
Bloom: 6.8 × 4 = 27.2 ml

pH @ 6.35
20220813 195522


They each got 20 oz of food tonight, and I'll be feeding them each a total of 60 oz, spaced out at each watering until the 6 gal is gone.

The Outsiders are doing good:

20220815 104549


We've been getting lots of rain, however, and they have been a tad bit overwatered. This was making the roots a bit slow to fully permeate the bigger pots... but they're now fully potted and should start bushing up.

We've had some heat spikes in the afternoons on a few days (104°-109°) which caused some minor heat stress, but that is expected:
20220815 104837
20220815 104841
20220815 104857


It is important to mist the plants, their pots and the area I'm growing them in when the heat spikes. This keeps the roots cool, which is the priority. If the heat held all day (like most mid summer days here), I'd need to put up shade screens (or grow under a paloverdie canopy - which is better because you can wet the canopy of the tree and massively cool & humidify the area beneath it).

Another note about AZ heat... it makes diagnostics hard. If a leaf yellows from overwatering or gets weak from something else, in this heat, you may never see it yellow or show symptoms... they'll die and shrivel in less than an hour.

I had mentioned I'd used some of Kyle Kushman's techniques on the tent crop (specifically the stalk bending to sculpt the plant, but I had started with the Outsiders first:
20220815 104604
20220815 104613
20220815 104619


Most of it went well:
20220815 104648
20220815 104714


This one was overdone and broke a bit, but lived:
20220815 104736


And these 2 branches were underdone, and stood back up a bit too much:

20220815 104820

I'd also snapped a branch off as well... but I got the practice I needed to sculpt the tent crop decently.

Got my TDS meter today. Tested the mix I've been feeding my plants, 634 ppm... and all but one plant are doing good. At this point I'm thinking it's nutrient locked. Which, in hindsight, I should have deduced because nutrient deficiency doesn't start presenting with this foxfarm mix untill around 30-45 days into flower.


20220817 212638


Why just this one plant? It had the least developed roots at transplant to this pot, and this lead to a bit of overwatering causing slower root development on top of this. From there, the plant didn't use up the soil nutrients, got fed too much... and locked. This was the cause of the yellowing (which I was a bit worried about generally due to not having a TDS meter).

During this feeding cycle, I have not fed this plant, and it has been slow to use up water, however tonight it was time to water it....

The initial ppm of the runoff was ~1330.

I flushed it with RO water (pH 6.4) till ppms read ~600.

Now... it's just time to wait and hopefully it recovers before too much damage happens to the fan leaves.

It's probably gonna be the runt... but it should still yeild some decent nuggets.

The Outsiders are definitely flowering now:

20220823 081905


It looks like Aug 1st was a tad too soon, Aug 15 is about the right amount of light/dark when including dusk/dawn in total hours of daylight).

I'll give a better update tonight. (I overslept today and only had time to do a quick watering before lightsout.)
