Kewl. I bought another one, myself; yet another 2 Ton unit, also from Surna. This one has different guts tho- it has a very different heat exchanger core, plus numerous safety features the other two older ones don't have like a flow sensor.

I got it for my usual half price vs retail, it was a new unit being returned to the factory because the customer supposedly freaked out over how big it was. In doing so, I did both my local grow store and the manufacturer a big favor by taking it off their hands... and I even wrangled a three month tip to tail factory warranty.

Now, I have so many portable chillers I could start my own convoy of grow trailers lol.

Cant imagine a 2 ton. My 1/3HP is pretty heavy.

Im gonna try and hook it up this week. Having trouble finding a suitable barbed/1"NPT fitting for my chiller. As it sits it has 1"FPT inlet and outlet.

Two Tons is a capacity rating, not its shipping weight lol It's about three hp.

Why do I want such a beast? For climate control (temp and RH), plus chilling for RDWC all in one system. I can remove and replace nearly any component while the rest of it keeps working. That goes for the chillers, too.

Get some photos of that shit up, I had a chinese set back, the hydro shop I ordered air tubing from evidently sourced from someone that has no idea of o.d. and i.d.
My airlines came off so much before I figured it out the damage is done. The pip dream was def looking good and I'll be starting some more.
Gonna trash some gear and I'm gonna put some new gear in place, never fucking ending.

So im mostly finished just making some field measurements of what I have installed so far so I can work off of it.

One issue i'm having is routing my return lines.

I originally had it planned so the control bucket and chiller were directly in front of the setup. Given the heating element on the baseboard I couldn't go thru that way. My only other option was my veg room and going thru the wall (as pictured). This puts the control bucket and chiller adjacent to the setup.

That last picture is how its going to be connected to the chiller supply. Going to have a ball valve and barbed nipple for drains.

The supply to the buckets is going to have a ball valve so I can close that and open up the ball valve pictures and connect a hose and turn the pump on to empty the system.

Im thinking of making the connection to the chiller a flexible connection, just to allow any variations with the rigid supply line mating with the rigid lines running off the chiller. And so I wont have to drill a hole large enough to get the union thru (which is about 1/4" on both sides of the pipe) so i'd need a 1-7/8" hole for a 1-3/8" O.D. pipe.

Already off 2" because my supply manifold is tilted the run along the wall is about 2 inches lower than it should be(this could be solved with an eyehook and some string to tilt the supply manifold up(right now its resting on the totes)) But I kind of like it resting on a tote. Saves me from rigging up some kind of pipe stand the mounts across both totes at the end to support the manifold.

Lost a union in all of this. For that ball valve/drain assembly I put the union on without the screw assembly. Luckily I left enough space off the tee to jigsaw the union off real close. Its not pictured but theres about 1-2mm of space between the tee and the union.

THinking about it i'd have to modify the piping a bit to allow for a barbed nipple to flex connection. But I think its worth it, what do you guys think?

I was going to pipe it like that. But since theres a wall where the chiller shoulda been im forced to improvise.

Laziness says just rotate the setup so its facing the chiller. Only the left 2 totes would be directly in front of the control and the right two totes would need to be 90'd to the control. shown below)

I'm worried that because the distance is longer than those two would drain slower or fill up too fast. This spacing also kills floor space and I wouldn't be able to fit another 4 site if I wanted to later.

So would 3 extra feet on one side make the much of a difference? Any issues you see with my flow setup?

And some grow pictures. In the cloner are some pipe dream clones

And those are the parents of those clones in flower. She stretched nearly triple her size. I had to cut them down a few nights ago. One I had enough time to screen. Gonna screen the other tomorrow.

Hate growing strains im unfamiliar with.

Blue OG - Was the only fem seed I had and I started it for insurance in case the pipe dreams were males. Was growing well at 0.6EC from seed. Currently the growing tips are turning yellowish green. At 0.8EC. I wonder if I need to up it to 1.0EC. I've been wary of over feeding and its like I cannot find a happy medium. Its either burn or deficiency.

I didn't really understand your pics. I run my chillers on a separate water circuit. If you aren't, I don't see a problem with feeding (filtered!) nutrient water through the chiller and onto the plants.

Which pictures? The ones I drew? Those black rectangles are totes. The blue lines are 1" poly and the red are fittings.

Thanks guys!

Almost coming up on my 1 year back at growing.

I feel like I went backwards in my quest for a better nutrient ratio.

One thing im noticing with this 1-1-1 is less nitrogen toxicities but more calmag issues.

It could be not supplementing calmag. Im realizing now these yellow tips and margins might be calmag. This time the older lower leaves are looking like K def with necrotic spots on the serrated tips on the leaves. This is definitely K def.

I may try full lucas with a 1-2-2 at half strength. 3ml/gal calmag.

Problem is im only feeding 0.6EC and 3ml/gal calmag is like 0.4EC.

I upped them to 1.0EC recently from 0.7EC and it looks like one of the plants took a halt.
