will it work?

you think a 3wx2Lx3H growbox made out of foamboard will work just by duck taping it all together? i use cfl and will be flowering 6 plants..for personal use,, i just want something cheap i am usually an outdoor grower

also i have seen foamboard like material with a shiny foil like on one side is that good enuf for a light reflector... all this is not permanant just want something to get by

ya i made a shitty pre veg box outta a shoe box, a little reflective surface and a few cfls. theres no reason, if properly light and ventilated, that this couldnt work for you

Check out my thread , I did something similar for only one plant though. Just finished it today
