Afghan Cino

Hi, I'm Cino from Western Europe. I'm a long time smoker but still a newbie grower (this strain will be my sixth grow and my first diary) and I'm not a native English-speaker. I've chosen Afghan Kush from Fast Buds in memory of the Afghan Hashish I loved so much when I was 20. I gave the seed a little rub with 180 sand paper and soaked it in X'seed from B.A.C. for an hour, then put it in a 36mm Jiffy-7 peat pellet. Finally, I put the peat pellet in a tiny germination greenhouse, keeping it about 25°C with a heat mat under a Spider Farmer SF1000 with power at 20%. HR is maintained nearly 90 %. It popped out about 3 days later and I let it 2 days more until I saw the root coming out from the pellet, then transplanted it in a 5 gallons fabric pot, under a plastic dome. As I've done with all my other grows, I used philosopher seeds' guide to prepare a good organic substrat, customizing it to autoflower : 70 % Light mix (Biobizz), 20 % Worm Humus (Biobizz), 5 % Coco (Biobizz), 5 % Perlite (Plagron) and added 18 g Nutrihemp (Trabe), 139 g Bat Guano Bloom (Guano Diffusion), 1 g Micromix Soil (Aptus) and 5,5 g Monster X (Platinium), all this on a 3 cm clay pebbles layer. I watered with filtered rain water (pH=7,0 ; TDS=20 ppm), only adding 0,5 ml/L Calmag (Biobizz) and 1 ml/L Mono Trace-mix (Canna).
