G.A.S Enviro V2 Fan Controller takes care of speeds for AC and EC fans and regulates on & off times for any piece of equipment in your grow room! Call us for more info.

the v1 to v2 upgrade works like this:

you send your V1 unit (which haven’t been sold in years) back to us, we ship it back to GAS the wholesaler,

they then do a software upgrade on your V1 unit to match it to the V2 software which then changes the AC intakes and outtakes from left to right and allows you to set and Min and Max fan speeds for Day and Night.

they also recommend a new temp probe if you went for this.

they then ship your unit back to us with the upgraded software and we get the unit back to you.
