As mentioned above started the new setup for the grow cab, couple a pics below.
Details again sorry. (not)
New setup for one shelf in the flower cabinet starting with the next grow. Im already using a duplicate setup in the veg space as a tester but i cant fit in there with the camera so a couple of pics with the build in progress on this one. Waiting for some 13mm ice pipe to arrive.
This will be a three site drain to waste or recirculating system easy to make either way and expand. I will be using 11 litre plastic pots filled with hydroton. So drippers in the top imagine that and the water runs out the bottom of the pots along the pipes into a bucket or res.
I will be running these as a sterile system and have a UV pond / aquarium unit connected in the veg room and will put the other one on this kit when complete. A pump pumps water into and out off the uv unit and back during lights on. Another pump attached to a timer pumps nutrient up into the feed lines which are going to be 13mm ice pipe, there will be three tees connected to the main feed line and branch of for each site which will have a tee at the end then a loop of 13mm ice pipe with holes drilled in it.
Nutrients will be Ionic single part Hydro Grow / Hydro Bloom and the additives will be Ionic Boost rather than pk13/14 and Ionic UV Balance to replace the iron etc that the uv unit strips out. So the res is always sterile and the nutrient being fed to the plants. If need be I can run some H202 through the system after each weekly clean out of the res and run that through the pots to keep the roots and hydroton in check.
Some pics below, the rings in the pots are what im using in the veg room. The plants that are in there where cut out of fabric pots, roots shaved off and cleaned then put into the hydroton and have been given a week more less to start recovering and the roots are already comming out the ass of the pots.
Strains are all Dinafem Site 1 Remo Chemo / Site 2/3 Purps#1. Nutrients as stated at EC1.2 Background EC0.4 PH when mixed with tap water is 6.3 and set at 5.8 and can rise to 6.5 and then be reset if need be.
