my bad, just kinda thinking outloud, wasn't reading more thinking about the overall implications - overall system savings - think they are talking cost savings - or some wort of weighted water and electricity savings
I will read it again, but it is totally good right, there is huge potential to get indoor farming cost competitive with outdoor growing - this is definitively the way pharma-cannabis should be grown
if something is going to be grown indoors with industrial sourced nutrients this is probably the way it should be done
