All depends on what is growing outside. If it photo's and they planted direct in the ground and if you are in a country that has lots of sunlight then i concur that outdoor grows will surpass indoor grows of the same strain. However, autos would be an exception to that rule. I do not doubt that some heavy yielding autos will out-do indoor grows while doing them outdoors but growing with the nft method will give you bigger plants with standard autos. A lot of standard autos could yield 3-4oz per plant outdoors but judging from what kushtie has done he is getting 3-4x that amount in his setup.
I could be wrong in all my above statements but that is what i am reckoning. Photos outdoors v photos indoors with plenty of sun = outdoor win every time. Indoor autos grown with nft v outdoor autos = indoor winner.
