Hey all, its our 2nd week after casing drop. Facing some issues with Night temp, sometimes it could fall to +12C, thinking about how to improve it. Also concerned about slow growth because of that. Using just 1/3 of Plagron recommended dose. Modified a bit my tank, made some technical window. Also set up automatic irrigation, because wool started to dry up during the day Upd Sunday 10.12.2023, Decided to put Babys finally to Seramis. Washing ceramics is some kind of hell: -First, I decided to sift all the dust through a sieve, stood in a half-bent position with bags of Seramis for 30m (my back didnt like it), but there was a lot of dust. -then I decided to check the Ph and rinse thoroughly. Although the package says 5.5-5.7 Ph, after the first flush with a balanced solution at 5.5 Ph, there was 6.5 in the drainage. - I was concerned by the very muddy brick colour water, then got tired of mixing 5.5 in a bucket for flushing and decided to rinse it with tap water from shower and then balance it back to 5.5 Ph . As a result, I poured from the hose for another 30 minutes until the water became more or less transparent. -I also tested FloraFlex discs, they drip great and, although round, fit perfectly into my square grow bags. -Meanwhile, the Milwaukee Ph meter broke down, even the readings of the calibration buffer were changing from 4-6 Ph within one minute. In the end, I spent another 30min and half a bottle of buffer on this too. It’s good that i had yellow Chinese Ph meter, which even after 3 years of rest in the box showed accurate buffer readings. -Finally, the Ph of the drainage was 5.5-5.7 and it was transparent, so I began to move it into the growbox. I sprinkled it as much as I could, it was impossible to dig deeper. The plants do not yet reach the matrix disk, so for now they will grow with the usual felt. -The cap of the tank is very thin and cannot withstand the weight of 2 grow bags, I’ll have to come up with something else, maybe I’ll put some kind of drainage grid. Watering will be from a tank with a mixed solution of 5.8 Ph and 1.1 EC.
