New System Part 6

Things are going well. Did some water testing and things look good.  We did have some trouble getting the tanks to stop leaking.  I have been unable to locate a shop that sells rubber grummets. Bit of a problem. But for now plasticine seems to work. The leaking makes the ground soft and then the tanks tilt more. Sort of self perpetuating....
But all good. Next job is to add in some NFT pipes to see if I can these going as well. (added a picture of it half done). Only doubt I am having is if the fish are producing enough nutrients to feed so many plants. The system is new so does need some time to get established. I've got a EC meter for measuring the amount of nutriens in the water and will start using it this week. Interest all the stuff I'll saved over the years from my earlier hydroponic farming as it is all coming back into use. Feels good not to have so much waste and also gets rid of a lot of crap in my store!!!

One thing I have not figured out yet is why the polystyrene trays have a series of channels and then a sheet that side on top with holes. Well I know if for irrigation but my question is why 10 run channels in the base polystyrene and 6 rows of holes. Means some of the plants have to struggle a bit to get down to the water flow. I've not [put this to clearly but it is difficult to explain. Anyway all going OK for now.
