Hi First post here. I've grown outside before but never inside. I was wondering if a box 18in tall by 18 x 12in wide will be enough room to grow 1 plant. I was given a few lowrider seeds by my friend. I am not expecting a big amount but was wondering if it is worth it. I can't really do a big grow op because i'm living with the rents. I only need this for this year. Senior at BU baby.
