So oxygen is being absorbed by the dangling roots and the nutrients being misted/sprayed are also being absorbed.

Yes.

The nutrients are not carrying the oxygen hence airstones in the reservoir do not in fact bring any additional oxygen to the table, their purpose,

As the air bubbles rise to the top of the nutrient solution, the nutrient solution picks up oxygen molecules as the air bubbles pass through it. The roots in an areoponic system are breathing air directly because they are not completely submerged in solution. So in fact the roots would be getting oxygen two different ways.

As in the case with the hydrogen peroxide, it is nothing more than purifier water with an extra oxygen molecule, but it is still in liquid form because the extra oxygen molicules are attached to the water (H2O). Hydrogen peroxide is in fact H2O2 because it has 2 oxygen molecules instead of one. When using the air stones some of the water grabs onto these oxygen molecules passing through it, and then the plants can adsorb them directly from the water. But the roots will still be able to absorb the oxygen from the air that it is in direct contact with also, giving it 2 sources of oxygen.

As a side effect of the air bubbles rising, the water is actually moving. This helps keep the algae down because it cant grow very well in moving water. That helps keep your nutrients fresher longer.

This is very cool. What is the container the strawberries are planted in? Is it something like 5in. vinyl tubing laying on a 45 degree angle with 2 1/2 in. holes drilled on the two upward facing sides.

I am not sure what you are referring to here. If you are referring to the picture of the strawberry's, I only have the image I found online. I don't know where it was taken. Though I am guessing it is a N.F.T. type system because most commercial systems are. Personally I took note of the square tubing, it may in fact be not be square tubing but say drain gutters on angle. But I was impressed with the way the plants are at an angle to allow two rows of plants in the same space as one if they were straight up instead. I will be using the square tubing to get the same effect.

I am not quite clear on Home Depot parts and picture. Does the Depot part form a watertight seal? I also didn't quite see how changing the tube converted from a ebb and flow to NFT. I must be missing something. I think I lost some of your closeup pictures.

The way the through hole works is, you cut a hole just slightly bigger than the threaded end in what ever you are using. Then place the O ring over the side with the threads. Then stick the the threaded end through the hole you made, and screw on the nut from the other side and tighten down. The O ring provides a water tight seal. I attached some pictures of anther project to give you an idea of what I mean. I haven't taken pictures of what I mean by inserting the 1/2 inch tubing but I will try to tomorrow.

Do you have a link for the plants?

I actually bought some before but I don't have the link right now, I will look it up later tonight.

Are you running most of your veggies then as ebb and flow?

I have 3 systems running right now and 2 are Ebb and flow, one is a drip. The systems I was running last summer were both ebb and flow as well. The ones I have planed for the future are ebb and flow, drip, water culture and I want to do a aframe aeroponic system probably for lettuce. I would also like to do a vertical tube aeroponic system also.

How many times in a 12 hour period do you cycle the system?

This varys depending on what type system I am using, what growing medium I am using in it as well as the temperature. Also on what the timer is capable of. The tomatoes are set at 30 on and 30 off all day and at night 30 on twice during the night. The others are using the same timer and the time ranges from 1 hr on to 1 1/2 hr on with no more than 1hr off at any time until dark. It goes on once at night from 11:30pm to 1:00 am. The goal is to make sure the roots never become dry.

I tried to make the post appear as yours does but I am not quite there yet. Please let me know how to make the portions of your messages look the way you make mine do in your replies.

First just highlight the text you wish to quote, then right click and click copy. At the top of where you type in the message there are 2 rows of icons, you are probably familiar with creating a link using them. The 3rd one from the far right bottom row is a pound sign (#). Just to the left of the # sign is a yellow icon. If you hover over it it will read "Wrap [Quote] tags around selected text",. Click on this and when the {QUOTE} {/QUOTE} appears in the message paste the text you highlighted in between them. Everything between these two tags will appear in the blue QUOTE box.
