Ttystikk's vertical goodness

No, Sir; fewer moving parts, just better integration with HVAC systems as opposed to the common scenario of treating building HVAC and growroom needs as if they're completely separate.

I no longer have a furnace AND an AC plant; they'll now be integrated, with the ability to gain serious efficiencies and thus reduce costs along the way.

In fact, I'll have just one compressor handling everything that requires heating, cooling or dehuey in the whole house, period.

I meant its not the simplest way of doing things...

I cant say whether water cooling/heating is more efficient than conventional methods. I've only encountered water cooling systems when the heat loads are huge...over 100 tons

Hey ttystikk how often do you change your nute solution and how do you do it? From memory you do dwc?

RDWC and every other week.

Cheers. When the plants are attached to the screen. How do you actually do the change, do you just have a spare bucket to swap while you change.

Considering heading this way, just a bit concerned I wont be able to control the water temp.

System sounds awesome!

I want to use liquid cooling for LEDs.

Yet It's completely acceptable for people to use 1/4hp toys for their RDWC? AND a minisplit for AC? AND a furnace for their house? AND electric heaters and separate dehumidification equipment? AND whole house AC?

The way it's currently being done is a fucking mess from start to finish, brother.

No one disputes that water is 30% more efficient than air at moving heat loads, even if the head unit itself is the same.

Frankly, a water cooling system is much simpler and easier to install than a air ducting system, and gets easier the larger you go.

And in fact that's really what I'm doing here; showing how well things work at the small end of commercial economies of scale.

Individual components are easier for most...no need to engineer a system that will do it all. And then if one component fails, the others are not affected. If your chiller fails, your entire system is down. If that happens in the winter...hope you have a fireplace.

I'm not arguing water is a much better coolant than air. I'm saying a furnace is generally a much more reliable machine than a chiller. Its pretty common for a furnace to last 15-20 years. Can a chiller last that many years?..maybe.

Back in the day, hot water heating (radiant) was the norm in multi story buildings, but its not any more. Why? I would say mainly due to the maintenance a hot water system requires over forced air. Particularly the expansion joints.

Are your cob racks mounted to the floor or ceiling? Or both?
Actively or passive cooled?

I have all my shit together to make the rack for my tent, but I'm not sure exactly how to mount it in there and have it movable so I can access the vert scrog.

My initial idea was to install drawer slides on the top front cross bar of the tent. The two outer cob bar columns will be able to slide from optimum light spread position, to the outer edges of the tent for screen access. I'm not quite sure what to do with the middle column to make it movable. Shoot, a third slide?

Or curtain rod thing with sturdy braces for all three...idk. Just thinking out loud

Forced air is cheaper for the builder, so of course it gets the nod. Yes, chillers can and do last 20 years. Where do you get your info or are you just making shit up? Yes furnaces fail, MOSTLY in the winter. Why? Cuz that's when they're being used, lol Water based HVAC is alive and well in new construction, especially in larger facilities.

Then you tell me there's no need to engineer a system that would do it all- what's your justification for this? I'm basing mine on lower cost, less maintenance and much greater efficiency.

The system I'm building also has individually replaceable components, they just work on a water system.

You're trying to be a devil's advocate, to what end? You don't seem to have the HVAC chops to recognize your own bad arguments, either. You in the field?

Why, exactly, are you here badmouthing the technology?

I'm not bad mouthing the technology. I'm saying your choice to incorporate your home heating and cooling with your grow room might not be the best idea, even if does save some energy cost. Time will tell.

LOL...I get my info from the 20 years experience of actually maintaining and installing this type of equipment. I've actually worked in heavy industry, have you? nuclear power stations, NG fired power stations, steel mills, pulp/paper mills, water and waste water treatment and hard rock mines.

I've never seen water based HVAC used in any of these places...water cooling yes, but never for environmental control.

Just for example. At the nuclear power station I worked at. They used a chiller system to cool the control room equipment. It consisted of two 250hp rotary compressors, not sure of the rated cooling capacity but they were replaced by one 50 ton AC.
