I have a dirty sump system so cleaning fish waste is a monthly chore.  I pump out of the sump into a media bed.  No problems with this.  I got the black worms to eat the fish waste and be a food…Continue

Rob do you out the green sand in the grow beds?  What would be a good amount to use in a system of about 500 gallons total water?

Comment by Jim Fisk on August 3, 2014 at 6:21am

Great advice Rob, haven't noticed it mentioned anywhere else. Thanks as always. Any more info on the "Minerals Plus"?

Comment by Rob Nash on August 3, 2014 at 5:23am

Jim, i believe most good garden centers have green sand. of course i get mine from Brite Ideas Hydro on S. Congress.  its good stuff.. has mag and cal and other stuff..

totally safe for ap, and does the job for long time.. i know a guy who only adds green sand once or twice a year and never has iron or mag issues.

but if you look at the minerals plus,, it has higher levels of everything.. so i use both of them now..

im doing some major iron test runs right now.. and will post my findings asap.

but go with the greensand, you wont regret it.

@Jack Dunbar - I have a similar indoor setup. For pollination I have been using an old electric toothbrush. It seems to work OK, and my plants set more veggies, although a fan may work just as well or better. I didn't have much luck growing tomatoes, but I only tried them once. Now that I have a better grow light, it might be fun to try again.

In my NFT setup, the pots are within 1/4" of the bottom of the troughs, just enough for the water to flow under and past them.  As long as the rafts are floating in the water, I really don't believe there is much of a minimum height.  I have seen rafts floating in 2" of water up to 6", I'm sure that there are those here that will suggest how deep their water is and I'm sure it works well for them. 

  There is not too much in aquaponics that is written in stone as everyone's situation is different.  Test which works best for you and go with it

Can anyone suggest a minimum depth needed for a raft bed?

Comment by Jeff S on August 2, 2014 at 4:29pm

Deanna, I use them for quick sporadic tests but if I am trying to correct a problem I'll stick with the API test kit except for PH.

Comment by Deanna Perry on August 2, 2014 at 3:54pm

Has anyone used the 5-in-1 test strips to test their water?

Comment by Cheri Bower on August 2, 2014 at 11:50am

I put together a filter in a 55 gal barrel that does three things for me... 1) lower spiral portion reduces solids that I can drain out every few days to add to my raised beds..2) feed out to my hydro lay beds from the middle of the barrel, allowing my red worm eggs and larvae to get back to my beds 3)since I have a floating bed in my system I cut two filter pads and set snugly on top of the spiral tubes...added a new line to the floating bed, keepign my roots buildup free. Still having trouble with the bell syphons in my shallow media beds so that is the next project :D

Tomatoes are self pollinators, since your system is indoors you may need the addition of a fan to help with strengthening the stems and shake the tomato plants to release the pollen.

  You also may have to start to pollinate the plants by hand, i.e. no or too few pollinators to do the job.  Again a oscillating fan will help.  Many backyard greenhouses do not carry a fan or it is too small to do the job efficiently.

  Your numbers are great so there shouldn't be any problem why your plants are looking shaggy.  Here in Wis. we are experiencing a tomato blight that is also affecting many peppers as they are in the same genus, my squash leaves are also exibiting signs of blight but all are producing very well, although my lettuce bolted also because it got above 75°F for a few days a couple of weeks ago.  It maybe that your heat is too high for the lettuce and Swiss Chard.

  I don't incorporate any other filter system except my media beds in my hybrid system and the roots in the NFT are pearly white so the media is catching quite a bit of solids before the water gets to the troughs to the herbs.
