Hi me and my friend are planning to buy a box we have 3x2x2m we will probably buy this box GrowLab Horticultural Grow Room - GL145L | because we find it the most fitting .. i think 2x600w will be enough or 2x800w? and and what i really dont know is ventilation i need at least know how powerfull should it be for this room and is it possible to make ventilation on this box in 3x2m ? i mean the pipes need some space and it will be really disapointing if we buy it all and it wont fit in the end any advice is welcome edit: we would like to make it hydroponic so if you have a system which would fit there in your head we would be pleased if you share that with us
