The 6 weeks of vegetation have paid out by giving a nice full room, we want to maximaze the use of the space. by topping the plant gows larger like a bush , and this is perfect for who has limited space like me. she still outgrown the room tho, with one of the 4 main cola growing above the height of the lamps, and one other cola crushing her self against the lamp ceiling (i fixed her where the light where not on to avoid burning her)
