Ron, I want to measure the ppm of my solution, The dip type nutrient meter has 3 different scales on it (1) is ppm 442 value (2) uS value + display x 100 (3) is ppm 'k ci' value

The type is Quick .Dip by hydroponics international. Q. which scale should I be using and what would an average be for general vegies cukes, Tom's, lettuce.

Try here. Conductivity

Also ron I was the guy that wanted to build my own set up using styrofoam as a container, just wanted to let you know that I tried the MK2 version with a much denser foam but still the water bleeds through the pores in the foam, Not giving up though because it looks great, I am trying to find something that I can coat the inside of the trough to keep it sealed, if anybody out there has a suggestion please feel free to jump in at any time.

Also if there is anybody out there from the calgary area interested in doing some joint projects please e-mail me chrhogg@home.com

Yes it pumps water up to the system.

Just a question about the Wal-Mart power head pump. I purchased one of these the other day, and wondering if someone could tell me the best way to modify the output to accept a hose. It's a 170 gph one that I plan to use with a small drip system that I am making that's similar to the 11 plant garden except that it drips from the top instead of flooding. And Ron I just wanted to say that this is a great site, and as current US Marine, I totally agree with everything you believe about the way American life should be. I mean, even though I am in the military, I think the government needs to pull it's head out of it's ass, and start worrying about things that really matter.
Thanks, Darren

Yes I used that kind for years and I am still using them. What you have to do is take a box cutter knife and trim that round ring around the pump out take. That will reduce the size but also makes it a square hose connector but a 1/2 inch soft rubber hose can be slipped over the square connector. You might have to put a small clamp or wire to keep it their.

Hi I'm the guy who asked the question about the Wal-Mart power head pump. Before I tried trimming the ring on the output, I tried different sizes of hose, and found that 5/8" hose fits perfectly without having to trim anything, and you don't have to use a hose clamp. It works great. All you have to do, is use a 5/8" hose connector with 1/2 inch threads to screw into the garden, in stead of 1/2 inch hose connector.

Where can you buy Calcium Nitrate, besides on this website? I would get it from here but my credit card is maxed.

Thanks

Agriculture supply businesses but you have to buy it in 50 lb bags.    I do except money orders.

what's a good way to cut the 2 liter bottles? so that the edge comes out straight.

 Scratch a line all the way around first. Then make a slit with something sharp. Then use a good pair of scissors and follow the line.

I found calcium chloride in liquid form at a local garden center. It is supposed to be used to stop blossom end rot on tomatoes specifically. It is made bt ferti-lome and hase 10% calcium by volume. (I think nitrate has 15%) Is there any reason that I cannot use this in my nutrient solution?

Who knows? Try it and let us know if it works.

Does anybody have any comments on what I am attempting to do? I work at an appliance shop and am taking a used refrigerator that has the compressor removed and stripping it out, mounting a fluorescent light fixture to one side of the cabinet and for reflective material I am using the insulating material from and old discarded dishwasher. For temperature control I am going to use the compressor fan that came with the refrigerator. My c02 injection system is comprised of some copper tubing a 8 dollar timer and an old water valve from the refrigerator I am using, the c02 tank I appropriated from a refer that was left from a college kegerator that got dumped at the shop one night. I purchased a fountain pump for 16 dollars (and that includes shipping). For the water storage I am going to use the vegetable crisper drawer from the refrigerator. For the light fixture I am using a 3 ft. double rail fluorescent fixture that the place I am working at discarded when they changed some of their lighting fixtures. I live in a one room apartment and space is tight but I am trying this idea out to see how it works. I am going to try one tomato plant and some herb plants to see what happens. All this cost me was the 24 dollars for the water pump and timer. Does anybody have any comments? e-mail me at gthomayer@yahoo.com

I have not seen this discussed anywhere. I made a small bubbler system, one 3-1/2 gal bucket, a 5" pot and perlite. Should I add water as the nutrients evaporates?, add more nutrients? or change the nutrients? How often? Thank you Larry W

Larry W. : If you added 3gal nutrient solution to bubbler to start with. You would add plain water until you reach the original amount added which would be 3gal in your case and then you would dump and start again with 3gal nutrient. I have found that a 5gal bucket would be the smallest bucket to use because of problems with ph rise and fall in the smaller buckets. Good growing Nurse Duckett

I'm new to this, and have great interest in this system as I'm a disabled Vet. and have 1/2 acre behind my home I could play with.

My question, can this system be used in conjunction with a fish farm, using no chemicals, just the water/waste product from the fish, and recycling the system?

Rick

Yes but you can only grow low nutrient plants like lettuce and basil. The problem with an Aquaponics system is that plants like a pH under 6.0 and fish like it over 8.0 so you have to compromise with a pH of 7.0 That way you can piss off both of them. 

I will be showing soon on how to build a small low cost aquaponics system that members can experiment with.

I would like to build the 11 plant garden but when I went to Home Depot, I was confronted with what seemed like dozens of different PVC glues. I was so bewildered I didn't know which one to get. Can you recommend one, or at least what it should say on the label.
