"Thank you for your advice. I have the test kit and will start testing more regularly. Will definitely also take a look at sludge buildup and explore adding to the fish population if necessary/ increasing cycle speed. All things…"
"This is just my opinion I haven't ran into this problem before. I don't think its a lack of nutrients (fish). I would say that it has to do with the depth of your bed. Here why. Personally I've grown in bigger growbeds using less…"
"That will figure will depend more on the amount of input feed going into the system and what plants you have in those media beds...
You may find that you need additional filtration between the beds and the NFT to operate them successfully and…"
"I built a 3'x5'x4" box painted black with a double pane glass front with 200' of black irrigation hose inside. The temp got really hot in the hose but as it circulated it didn't seem to keep up well. I ran it during the…"
"Def normal to have to add water -- lots of evap from low humidity --10% not unusual. Not sure how to answer your other question except generally all the beds will eventually cycle together, occasionally, so your sump tank and FT need to be able to…"
"Thx Jim for the info. Some of this i had started but just didn't get it done in time. Im looking fwd to killing this next yr lol I just added four more grow beds so I have a total of 8 now cant wait to get fired up again Thx for all your help…"
"Here in So Cal I'm paying $3.35 each for fingerlings. They are pretty good size (4-6") and very pretty Blue Channel Cats, but I am more interested in delicious than pretty. Next time around maybe I'll see if I can get them shipped…"
"How have you set up the discharge cycle. They should not all fill together, or drain together.
5 beds on a fifteen minute cycle. Each bed needs to start draining 3 minutes after the last bed.
How big are your beds/sump tanks."
"Wow, that sounds like a good price. Here in So Cal I'm paying $3.35 each for fingerlings. They are pretty gpood size (4-6") and very pretty Blue Channel Cats, but I am more interested in delidious than pretty. Next time around maybe…"
So I set up my system last December 2014 and I was "cycling" initially just by circulating water for a couple of weeks. I added some lettuce, basil, brussel sprouts and onions in the growbeds with a sprinkle of spinach seed. Then I started adding…See More
"Thanks Jim for the pic. I have been thinking about something like this for a bigger system I'm going to build this Summer. The cost of copper and an exchanger was somewhat of a deterrent but seems like CPVC works just fine. "
"3000 ladybugs did a splendid job of clearing up our whitefly infestation in our 24x24 GH. I ordered 1500 but after 2 weeks lost in the mail the vendor sent another 1500 and of course they BOTH arrived on the same day 3 weeks later. The original box…"
"Arthur, KISS. The little pump sits in the sump and pumps sump water. It heats about 2500g of system water. If you used say copper at great expense these days, then you would need a heat exchanger in the sump but I try and keep it simple and…"
