My Lettuce Table (Part 2)

(Click on each photo to enlarge)

Take a 4 x 8 piece of metal roofing to make a slightly sloped table.
Put a manifold with emitters (we call them piddle tubes) on the top end.
Cut plastic tubing into bottomless 2 x 2" pots and seed them in a tray.
Set out the seeded grow tubes on the sloped table and feed them with nutrient solution.
Drop a fountain pump into the container and put it on a programmable timer.
Put a removable clear top on your table to keep wind from knocking over your plants.
Let the solution drain back into a plastic container at the bottom end.
Harvest your greens with the roots still on - they stay fresh longer.
Clean and sterilize the grow tubes in your dishwasher.

I can go away for days and my lettuce is taken care of.
Transplanting is like moving a chess piece - without disturbing the roots.

just wonding
by: 2T

did i miss something it appears that the water source is exposed to sunlite and might be inviting algea growth --please explain

Algae have not present a problem. Yes, the water running down the slope is exposed to sunlight. However, that surface is soon shaded by the foliage.
What's more, the algae are constantly removed from the solution by a filter in the reservoir.

Looks great!!

I have been trying different hydro projects from time to time and look forward to trying this one. Looks simple and fun.

growing medium
by: dave

what is the growing medium in your pots. Pots look like 4 inch pvc, I believe you said 2 inch. great idea. I was looking at using corrugated roofing but could not figure out howto do it. Have you grown anything else but lettuce in this installation?

sprouts
by: dave

Any idea how this would work with sprouts? Perhaps us smaller diammeter tubes banded together for stability.

tubes
by: John Stone

Helmut,
What are the tubes made of? did you say 2" tubing?

Thanks John Stone

Answering John and Dave
by: Helmut

"Pots" are thin-wall PVC pipe, 2" nominal diameter, as is used for installed vacuum cleaning systems. I chose it because it has the thinnest wall. I cut it to 3" length.

As medium I use Miracle-Grow Seed Starting Potting Mix, for simplicity and convenience.


Correction
by: Helmut

The length of my grow tubes is 2", not 3". My mistake!
