This whole indoor hydro thing really bugs me. People, there is no difference. Nix, nill, null, zip, zero.
The only difference is one is most likely grown in soil and "hydro" is soil-less, usually grown in coco or directly in water, seriously makes zippo difference, so paying extra is just down right silly IMO. All hydro means is growing without soil, which is done mostly to avoid bugs and it is easier to control nutrient feeding. But does it make the bud better. No.
What is actually important is the grower, you can get some mad stuff grown indoor in soil and some crap weed that was grown in a NFT / flood and drain system.
Just wanted to get that off my chest. Have a happy day everyone!
