well bee updating equipment and doing some minor repairs, developed a power issue to 2 strips of the light panel i made so had to clean the contacts and re-crimp them on the strips, in process of remaking nutrient manifold going to get away from the 8 tube heads and make 4 tap offs to connect tubing to in the PVC pipe and use a ball valve to adjust flow
So prepping for some heavy duty growing , waiting for filament to come in for 3d printer and will be making lids to cover my net pots to cut down on light on the growing media and less chance of algae issue into nutrient solution , I have used a few ways off and on in various plant cups one of which is sealing top of net pots with painters tape. below shows net pot - rockwool plug vial and a semi finished grow set up for grow pot.
Have new plant beds in process of being put together which will expand me to 10 racks 3 tier high so just under 800 growing slots on NFT to grow and share with elderly and a few friends and those with around that can use the assistance to put some fresh produce on table for their kids. so will be doing some lettuces, Tomatoes , herbs, some dwarf egg plant, and hopefully I can find a dwarf / miniature sweet pepper to try. if anyone know a good variety of a small sweet pepper plant variety let me know
so for seed starting i use a 40 dram plastic vial they use in pharmacies for meds, picked up a couple cases. They fit a 2 inch net cup pretty good although this net pot has a slightly wider top area due to longer lower net cup.
I mark where a the liquid level in vial come up the lower net as shown then as the net cup with rockwool growing media is inserted it draws water up into the rockwool , after an X slit will get cut in top and poke a hole to plant seed in and that is it. one flat down 29 to go for when get set to start seeds. soon as filament gets here for 3d printer i will be making two piece lids to cover the top of pot
so i have a little jig that fits snug on the top of pot and just cut slits with a razor knife and center can fit a 3 mm round dibbler to poke a hole, then just peel tape back and plant seeds
