On the 5-6 day of the sprout, I gave a small illumination with philips UV lamps - a mini solarium for the face (140w like), literally 5-7 minutes no more
I have a diy cooltube from a microwave box, the lamp also has an aluminum reflector, all this is in the box and equipped with a 180m3/h fan for cooling. Below there is one glass and after a 1-2 cm layer of air there is another glass, both of them about 5mm thick. I don't know about the efficiency of heat removal of this technology, but let it be so for now. The temperature has not risen above 33 yet, but I try not to leave one lamp without any blowing or at least a humidifier. So it turns out a 44x66x145cm box covered with two glasses and a lamp at a height of about 150 cm from the floor. And the flower pot itself is on the boxes. This can be seen on some photo in the gallery.
Green-o-matic (GHS) 7 days, HPS (ДНаТ) 250, ground "Fasco" (Фаско) for roses (ph 6-7) + for azaleas (ph 4.5-5.5) + organic mix biohumus (ph neutral) + sapropel + perlite + vermiculite + coconut + boiled expanded clay 1-2L to the bottom, the pot itself is 15L like, everything on the eye bodyazhil ~70% is a chamfer for roses, not counting expanded clay; the mode right now put 20/4 to there wasn't much of this randomness in the first few days. I pour filtered water (Ph ~ 5.7) from the tap for 100-150ml as the ground is dry for 1-2 cm from the top, before that, I just sprinkled with a standing tap, too (ph ~ 7.3) I don't remember the exact values, since the ph-meter lives on a kind word, but judging by the observations and after calibration there are approximately in such ranges of values.
