My second experience. Fast growing seeds

Peace everybody!😊 As I’d predicted, the last 6 days brought big changes – the little plant turned into a very cute little bush. So, it’s the first day with sodium lamps. (I turned them on almost an hour ago). The distance from the lamp is about 25 cm – I think I shouldn’t put it closer. I’ve set a computer cooler inside the box 120x120, 3A for additional air flow, it’s powered by adapter. I’ve bought this adapter with a view to (in theory) a few more coolers. The complete construction (including cool tube and blowing) is quite noisy, but when the door is closed I can barely hear it, so it’s allright. Watering: I water it with pure water or with a light solution of liquid vermicompost (3-4 times lighter than by instruction) every two days. Today I’ve added 0,5ml Uniflor Micro per a liter of solution.
