Is hydro the way to go instead of soil?
Hydro grows quicker compared to soil.
Although soil may be slower, overall plants in soil will usually show better health. Growing in soil act's as a buffer, so if you overfeed, fuck up the pH or forget to water them it's going to take longer to take effect then hydro, which is basically instant.("buffer" means the length of time it takes for things to reach peak. For example, when your loading a video and it may take a few mins to buffer to 100% this is the same case when growing in soil, but with hydro there is almost no buffer, as it loads/works instantly)
You should keep in mind, if it's your first grow things are bound to go wrong, and you will learn from your mistakes. IMO though, growing in soil would be an easier option for you to start with. Like I mentioned with the buffer, if your girls run out of water in your hydro system they can be completely dead and dusted within a day. In soil if this happens, the plant's will do the same but at a MUCH slower rate, so they could survive up to 2-3 days with no water.
I'll also add, that plants grown in soil give a better taste and high IME. And Hydroponics isnt stronger then soil. It all comes down to the strain grown, and how healthy those plants are.
