Firing up of NFT system delay

No time to work on the NFT system Sunday. The forecast for the next couple of days is rain, so I hoping to get the system fire up sometime this week.

Electric outlet in place.

I was going to cut the patio pavers to size early to day, but could not find my masory saw blade. So I will have to buy a new one some time this coming week, before can cut the pavers. How ever, I did add another 2x6 to the framing. Which I then mounted the the electric outlet to. You can see it here with the weatherproof cover on it.

Pavers added to top of walls.

Did pickup patio pavers to top off the tops of both walls. This also gives the walls an extra 2 inches of height, which allows the NFT tubes to clear the top of the nutrient tank ( See third picture ).

Still need to cut a slot this one paver to allow the electric line to pass thru.

Here you can see that the NFT tubes just clear the top of the nutrient tank. I also decided to reused the old tubes for one more year.

Finished second NFT support wall

Finished the second support wall last night. You can see the electric outlet hanging near the top of the wall.











The new wood framing made out of 2 x 6's was started tonight, but ran out daylight to get much done with it. Now need to get some 2 inch pavers on top of both walls before I do any more framing work. Will try to get pavers tommorrow after work.

Now I need to decide if I going to reused the existing PVC tubes or replace them with new ones. New ones will allow me change the spacing between plant holes. Will sleep on it tonight.

Old support structure taken down.

Ran out of time tonight trying to get second support leg/wall built. Did get the old NFT support structure taken apart and ready for the garage man.

New support structure for NFT tubes

The NFT tubes support structure is getting rebuild. The old wooden structure is being replaced with concrete blocks for the legs at both ends. Here you can see the one end being build. The other end will be bit harder, due to having electric line coming up thru it. I'm hoping to have the other end completed tomorrow. The new legs/walls are 39 inches wide, compare to the old structure of 24 inches. This should allow me room for four NFT tubes.

I thinking that I might try a doing a deep water NFT system with two tubes this year. Along with the standard NFT system.

NFT tubes support legs are cracking.

Today when I was placing my NFT tubes back on the support structure. I realize that I never got the electric outlet wired up on the stand. So I went ahead and wired it up. I the process, I found that the wooden legs of my support structure were all starting to split apart. Most of them didn't look like they would last another season. So I decided it time to rebuild the structure. So this will be one of my projects this coming week. It also means I have to wait until next weekend to fire up the NFT system, weathering permitting.

This season I'm also planning on adding sensors to the nutrient tanks. Sensors will report the status of the following:

1. The tank water level
2. That water is actually flowing from then return pipe.
3. Pump still has A.C power ( Gound fault has not tripped )

Cleaning the NFT tubes

Getting the NFT tubes ready for the new growing season. I'm scrubbing the the insides of the tubes, by closing off one end. Adding 1/2 cup of bleach with 1 cup of water to the inside of tube. Then using a piece of 1/2 inch pvc tubing, with a sponge attached ( see picture ). I pull the 1/2 inch tubing back and forth with some downward pressure thru the NFT tube. Works quite well.

I purchase some sweet 100 tomatoes plants early today. I hopine to get the NFT tubes up and running by next weekend, so I can insert some of the sweet 100's in the NFT tubes.

New support structure for hydo buckets plants

My support structure last season started to fall apart from weight of plants. So this season I wanted a stronger structure. Here I'm starting to put together 1 1/2 inch pvc tubing for the main support poles. Still trying to come up with a roof structure to put plastic on to keep rain out of the buckets.
