Hello everybody, this is my first grown report and my first grown session.... so be indulgent please, i never do that before.... Let's have a look about my gear: mylar box 900x500x1600mm 400W MH/HPS with cool tube. home made hydro system include mixing pump, air pump, water heat. air intake 100m3/h. air out with carbon filter 300m3/h. cool tube 300m3/h. T° controller with 2 speed dimmer, 1 for the cool tube and 1 for intra/extra linked together. 3 liters airpots. root riot starting cube. powder feeding mostly indica. auto controlled humidifier. ec and ph tester. starting with 4 kalashnikova from green house seeds... now the pics... the empty box: seeds in germination: all seeds popped in 2 or 3 days then put them under 400w MH in my mini green house.. babies in veg: hydro veg +5 hydro veg +9 this one died, she was the most beautiful... hydro veg +23 hydro veg +25 babies in bloom: bloom day 00 bloom +5 (today) Settings: for the germination phase: just tap water ph 5.5, EC 1.1 in spray over the root riot, once a day (before night). air temp 26-29°C. hygro 80-90% RH. for the veg phase: ph 5.5~5.8 EC 1.8 (with tap water EC 1.1) at the start then went to 1.3 before bloom with only powder feeding (addition of 12 liters of tap water PH 5.5 EC 1.1 every 5 days). water temp 22~24°C air temp 25-26°C the day and 19-17°C the night. hygro 60-70% RH. for the bloom phase: ph 5.5~5.8 EC 1.72 (with tap water rectified to EC 0.7) water temp 22~24°C air temp 25-26°C the day and 19-17°C the night. hygro 55-60% RH. these settings will change along the time....
