How the index valve works, do you set it to water one GB at a time? how big is your Sump tank? How big are the GB's. I just want to size my ST properly. What do you recommend for an index valve? …"
"little did I know!! is the index valve the same as the sequencing vavle? How does it work? If I plan to have 6 GB's and I want to start with only two, can it accomodate for expandability? I love it. I am almost there…"
"That's the reason for the sequencing valve and repeat cycle timer. It allows you to fill and drain the beds individually in sequence, escaping the need for a gargantuan sump tank. It's the whole 'beauty' of it."
thank you very much for your valuable feed back. I really appreciate the "support" I am getting from you regarding "my thoughts". It is good to know that someone else shares the same convictions. Also, I…"
This is question for George,
you mentioned that you have one pump, one timer, one index valve, and six GB. How big is your sumb tank? if all the GB's are draining at the same time, you must have a ST big enough to accomodate…"
Looking good. What part of the country are you? I'm in New Hampshire and it can get pretty cold and plenty of snow. I'm going to build a Greenhouse this next summer and I'm checking out all my options. Please keep us…"
Well folks, my walapini is up and running. A far cry from the hole in the ground pics I posted earlier this summer. Whats in it? 1 -75gal fish tank, 1-75gal sump, 2 -45gal biofilters/growbeds, 1-2*4ft DWR, 2 - 2*6ft raised beds. 2-4ft -250w…See More
"15 minutes on/45 minutes off, would likely 'do the trick' for you.(or increments of 15min).
The "ideal" pumping sequence would be one that does not allow the grow bed to completely dry out (this will be dependent upon what media…"
Now changing subjects on you. I initially used syphons, they are tempramental. I looked for other options, I find timer, standpipe and a drain pipe next to it. I am sold on the idea, but I have not bought the timer…"
"Absolutely, positively no reason to cut them to 12". 20" would just give you MORE bio-filtration and mechanical filtration within the SAME foot print.
If you will pardon the diatribe:
Somewhere, at some point, a scientist (or grad student)…"
hello, everyone. I have bought IBC tanks. I cut them where the top and the bottom will make grow beds. each one is 20inches high. I really hate to cut them down to 12. Any reason, that we do NOT make the GB deeper than 12. Would not that help…See More
