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.
Code:
Not really "IN" the solution but to the roots themselves. Although I would still use a air stone in the reservoir because it helps to circulate the water when the pump is off, and I don't believe the roots can ever get too much oxygen.
So oxygen is being absorbed by the dangling roots and the nutrients being misted/sprayed are also being absorbed. In the aero system are these two processess independent of each other. 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 you mentioned, keeps the solution moving? Sorry for such an involved question but you seem to be able to handle them with ease.
Code:
The square tubing is key to the design because as you can see it allows 2 rows of plants in the same tube (maximizing space and nutrients). I attached a picture of a commercial hydroponics farm using the same type system (its where I got the idea). Note: the plants are high enough to walk under making it easy to pick the berry's. Mine will be waist high though.
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.
Code:
No, it will be a flood and drain system (no misters). The through holes sticking out from the end caps will be the inlet and the one going out the bottom will be the return. I attached pictures of the through holes that I use. I get them in the electrical department at Home Depot, they run $1.97 each. Half inch vinyl tubing fits perfectly in the center of the through holes, so all I need to do to adjust the water height is use a longer or shorter piece of vinyl tubing. If I want to change it to a N.F.T. I'll just take out the vinyl tubing
.
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.
Code:
They are actually dormant (strawberries) but will be full size in about 2 weeks (much faster than seeds).
Do you have a link for the plants?
Are you running most of your veggies then as ebb and flow? How many times in a 12 hour period do you cycle the system?
