so im doing a single plant grow in a 4 foot tent. but i realize that i might not have enough vertical height room. so my question is, would my plant grow alright if i was just to put it on the floor in my spare bedroom with my grow light above it without using any reflective materials. everywhere i read says you always need reflective material, but i notice that larger medical growers usually just have a bunch of plants on tables with lights above. there not wrapping mylar and stuff around there plants.
