Hashyanswered grow question 3 years ago Hydroponics is a different ball game altogether. Hydro you need to use a different ph range then soil. Soil you can get away with water for 1st 3 weeks, hydro you pretty much need to add nutes from the start. Mistakes take longer to show and develop in soil, hydro is quite the opposite, mistakes show quickly and progress quickly so you need to be on your toes with hydro.
