hi guys newbie here so please be gentle. im in the process of finding my way round and this is my first post/blog.any ideas would be appreciated and advice gratefully recieved. my objective is to creat a basic stealth box for growing some hybrid sativa indica strains 12/12 from seed. the equipement is locally sourced, used and cheap. 2x250 hps security lights 2x12v computer fans 12volt mobile charger 300 watt 240v speed controller. couple of 125mm flanges and some ducting. im about 80% finished as far as my cab is concerned.all i have to do now is connect my outlet ducting straight through to the roof vent,get advice on my c02 requirements and start laying down my beans. strains are as follows. swiss cheese bubleliscious ak48 4 inch rockwool cubes with covers. formulex ph water. method.11 days under 2x55watt daylight balanced bulbs then under the 250 hps untill finish. havent chosen which soil to go with but light mix or all mix with hesi bloom and dutch pro explode may be the way. will switch on second 250 hps as plants get bigger. room dimensions are roughly 3 feet by 2 feet by about 40 inches high(full grow height to top of cab.) im looking at the co2 boost and have a 6 inch oscilating 12volt campervan dashboard fan for air movement(not pictured but will follow as i update blog.) my first question will be regarding co2 as ive never used it before. i was intending to use the light covers i have that fit to the underside of the lamp housing to extract 80% of the heat in the cab straight outside through the roof vent.using the co2 boost and the fans on very low just to add movement within the grow room.temps dont get hot in there due to the lamp covers and fans.i can also get the plant within 20 cm without any heat issues. total cost so far £15 cab,flanges and 12 volt fans a tenner,2 lights £70 a fan controller £6 and some ducting along with rockwool and formulex which was another 25 quid.so about £130-£140 for the setup. will update soon but i need advice on whether i would get enough co2 from the co2 boost to keep my girls growing nice and steady or should i just forget about the co2 and just have air in and out connected to a thermostat and forget about it.
