Good call on that one, I didn't even check to see if it was hydraulic or pneumatic. Yeah, I bloody ordered the pneumatic one, no worries though, I sorted it out. The hydraulic regulator is on the way. Thanks for the heads-up, and thanks for all the help.

Atomizer, I found a pressure regulator valve, it was only $25. I'll bring the bladder pressure to 78 psi, and regulate the flow pressure to 80? 100? (Whatever you think is optimal.) This should give a more even nozzle flow rate and increase the duration of the tank charge, plus about 2 more...

Yes! My tank factory precharge is at 38psi, I'll increase to 78psi to make the run-out pressure 80 psi. I tested it only once, and frankly I was a little wary about pressurizing past 120psi. It is certified to 150psi, but ... - On the other hand I have seen systems that are using R.O...

Nutrient lockout and precipitation are overcome by creating balanced solutions at the correct pH. Concentrated solutions are kept separate until diluted, in the proper order, to make a working nutrient solution. Using HPA systems it is possible to keep incompatible solutions apart. Has anyone...

Greetings Atomizer! Based on the tomes of your work that I have read, you are a repository of aero knowledge, and I thank you for contribution. To me, you are Dr. Atomizer. From my initial testing, I can see how the volume can be ascertained by the pressure. Also, the fixed volumes of the...

Hey guys, We are growing in air, not mud. Let's stop throwing it around please. Today I started the cloning process. I air layered each of the plants with three air layer sites, so I will have 12 total plants. I've used this method before with great success. I found a very easy method using...

Wow! That is a great point, I can do the maths on it and measure the mass, Fractional deviations from the calculated mass would be a harbinger of nozzle failure. Nice point there. - Oh, I wanted to disconnect the rez after filling it. This would keep the nutes in a sealed container and...

A thought just dawned on me, and speaking of accumulators, I need to figure out a way to know how much nutrient solution is left in the tank. I'm thinking of loading it with nutes and letting it run down/out without a reservoir connected all the time. I could just shake it, but I want something...

From my point of view, I see healthy, well formed roots that look like they could support massive foliage growth. I hear that the spray velocity carries the nutrients to the center, but when it becomes dense, it needs to be cut and separated, to increase the surface area. PetFlora, you also...

I really don't think this is complicated,,,women, now WOMEN are complicated, although there is a real world advantage with them...and let me tell you about the hours I've spent trying to figure them out... :) Humor aside, Nice! Great stuff, the spray timing is requisite information. I was...

I reread some of my previous posts, and it caused me to delve into an analysis of a plant’s cellular response to HPA. HPA causes a plant to produce fine microvilli from the root cells to increase water and nutrient absorption. I have also read that this response takes a few days to emerge...

Hi Pet Flora, Dstroy, and Anothermeduser, I just read through posts #40 -49, and I'm going to reply to all in one post to keep it all together. One point that I should address in general is EC. I'm glad that EC was posted because ppm's can differ if spoken about in terms of TDS. I use ECx700...

Crazy week. I mixed up some more Jacks. I went with a N-P-K-Ca-Mg ratio of 2.5-1-2.8-1.3-.6 , which I think is pretty rounded. The K-Ca-Mg ratio is 4.4 – 2 – 1, not too shabby either. I diluted the mix to 700 ppm, or EC 1 and checked it with the Blue Labs. Here is the profile: I had to...

Anothermeduser, I hold farmers in the highest regard; we have elevated our species from simple carnivores to the sentient beings we are now. All of your experience will help push us forward, and I'm grateful that you are willing to share, so that we might pass our knowledge along to the future...

Hi guys, excellent points you both make, PetFlora and Anothermeduser. You both present persuasive and considerable observations based on experiential knowledge. As I digested these statements, I weighed them against the following points, and I have been inclined to present these additional...

Those look pretty neat. I'm not sure about some of the green light claims though. The carotenoids might be able to capture some of the energy and use it through ETS, but It's not as efficient as the chlorophylls. Besides, I have over 6K actual watts in full spectrum LEDs, if I get anymore...

Last year I took cuttings from my last harvest, 10 weeks into flower, with the thought that I might keep a few mothers around. This was back in July. I put them into a LPA cloner that I previously constructed and I let them go over the summer with a 300W full spec LED. The interval timer...

I used GH nutes for a few months and quickly switched to my own because they would start out good for a few days, but then the plants would start to show deficiencies. If I didn't change them out weekly, or if I tried additional dosing to reconstitute, the plants became stressed. The pH swings...

The seedlings are larger now and I’m tired of hand watering. I needed to automate, so I constructed a drip system. It took a few prototypes, but I have achieved simplicity and mobility from spare parts. I used a timer, GPH pump, flex tubing, 5/8” PVC tubing, clothespins, and duct tape to make...

Nice prolific growth, It's has a lot of lateral root development, and it looks like some fish boning on the interior roots. I'll bet that the increased O2 has a lot to do with it. I tend to use 6" pots, and cut the lattice to accommodate for larger root growth, without losing the stones...
