The only ones the MIGHT even do that at all would be some of the Super Auto lines from Flash Seeds. If you're looking to stay under 8 feet, your options are limitless. LOL
ya a did not word that right lol I found an auto strain "bruce banner" , I am just trying to figure how high to make the ceiling in my grow room, with the light needing distance from the plants, im wondering what size pot to plant them in ,{ i heard that the bigger the pot the taller the plant ? with all that in mind how high should the room height be ?
Take any auto. Put in 1/2 gal or 2 liter soda bottle of coco. Feed 2x a day(it's not as strenuous as it seems) and grow 2 oz plants. Save on medium, space and grow many strains at once.
