What's the Diffrence between Hydroponics / Aeroponics , I have heard of them before when I was 15 but I have never figured out what the diffrence is.

Aero ponics uses a nutrient rich highly oxygenized mist over the roots which achieves ultar fast growth while hydro means a flood or flow of water submerses the root setup in water.Then you have hybred versions like dwc,NFT,combo aero/ntf and so on.Aero grows the fastes of all.My aero grows veg 10 days and I harvest 5 weeks of flowering.

what kind of stuff do you need for aero?

res,pumps,root chambers,manifolds,hoses,misters,ph pen,ppm meter, hydro nutes,timers..the basics

aaa what are the diffrent levels for growing pot

ex. Easy , Medium , Hard

For me I rank the ease and simplicity of growing methods as follows easiest to hardest.
1.aero
2.hydro flood and drain ie ebb and flow
3.soil
