well i figured why dont everyone do this?. I mean, The whole idea is to get more lumens to every part of hte plant. So what if u bunched up all the nodes/branches and made more space . So thats less space, with same or more light.
Someone would be able to put 4 plants in a 2x2 and bunch up each plant and have a really good light source to the bottom nodes and also be able to use a smaller light setup.
If u have a smaller space , u have more reflection to the lower nodes.
why doesnt everyone grow suppercrop
