Im building a 1.75x3.5x6 ft (21x42x72 cm) grow box. I have a 400w hps w/ open wing style reflector that im going to be using in it. I just need some advice/opinions on a few things since i have no experience.
question #1) will a 6" 240cfm duct booster with a passive intake be sufficient ventilation? i will have maybe a 6" oscillating fan inside as well. the hps is a open wing style but i think im going to need to look into building my own cool tube or glass shield. thoughts?
#2)i plan on using the dwc/bubbler system. i wanted to put more than one plant in one big tub. is this a good idea? will the multiple roots become a problem? how big of a tub should i use w/ how many plants for this space if this method is possible? or should i do the main reservoir with multiple grow sites? how big of container for each grow site vs reservoir? how many plants can this lighting/grow space grow in general?
#3) how big of a carbon filter do i need to build for this box? what size pipe and how long of a pipe do i need?
Thanks any info/advice is appreciated.
