Not to be a joykill, but you can hardly call this a vert grow. Only thing that's vertical are the lights hanging top to bottom. If you wish to gain the benefits of vertical growing, you should at least have more than a single level of plants (set up in a stadium, coliseum or octagon-thingie). At least don't be disapointed that your yield closer to 1 than 2 g/W not even counting the many watts needed to veg those big plants.
just my 2p worth
Btw. 74.4oz/1800 W is "only" 1.15g/W. He squeezed 2.14g/W out of his flooded vert in less time.
Yeah but how long time did he veg these trees for? Compare this grow to his space ship grows and it's clear that it's two completely different concepts. Anyways, it's just a word so who cares, but as said, if you want to maximize g/w/month I would be surprised if this set up was able to compete with a multilevel vert set up.
