Here is a few pictures of my newest vertical system. I built it completely from materials form Home Depot and other equipment suppliers. Basic frame made from 2" pvc central vacuum pipe. Bottom gutter made of 4" PVC pipe sections connected (glued) by 45 degree 4" PVC elbows and then cut in...

This is a beautiful plant. Out of curiosity, how long did you vegetate it for? Thanks.

There is no difference between so called water called water cooled grow room setups and using air conditioning. Although you are right about the thermodynamic properties of water, it is, however, of no relevance to this comparison, as in both cases heat absorption is performed by the same freon...

I was pricing out some equipment and was amazed at price differential between water chillers and air conditioners of equivalent btu, ratings. Then realized that most likely this difference is due to one part - titanium condenser (cooling coil) that has to be chemically non reactive to protect...

The claim that water cooling the grow room is more efficient than using air conditioning system seems groundless to me because the same exact method of heat removal is used in both cases, and water cooling involves more watts or energy used per btu of heat removed. There is however one possible...

Good question. I have been thinking of this lately too after having watched the Hydro Innovations video. Although the idea of using water sounds very cool, it seem to me that some of the efficiency is in fact lost in the process. In case of using Air Conditioning to cool the air directly...

Hi guys! A DIY water chiller is exactly what preoccupied my mind for the past couple days. I almost bought a freezer to try conversion, but here is what i found online: http://www.beananimal.com/articles/dorm-fridge-aquarium-chiller.aspx Very detailed and useful. Still working on trying...

That is what i ama considering. What were your thoughts on pros and cons of using the building supplied water for cooling? The only thing I am thinking of is excessive water consumption, although it would probably not be noticeable. What do you think?

Hey guys, I justfinished my first vertical grow and am quite happy with the results. I did better than ever before in the way of yild per lighting used. I was using 2 400 Watt HPS lights with 16 grodan slabs around these. Got 710 grams with AK 47 in about 7 weeks total time, which is about 40%...
