Thanks again for the info.
On my outside setup I have a 44 gal gray trash can that I use but it dose not recycle the
nutrients. Just on a timer and a full tank will last hmm 4-5 days.
And I have been running it for about 3 yrs with no algae growth.
So I may in the green house try and use a small 10 gal can that's inside of a 25 gal can so that way I can put insulation around the small can that's in the big can LOL that make any sense.
I know this year we are building a shade house to shade the plants last year was hard on them the ones in the ground do fine but the Verti-Gro was just ok.
I try to post some pics today I have a meeting at noon here.
Ron.
