Aerogarden Questions

I have never grown but I thought of it one day and became obsessed. The aerogarden looks the easiest to use but do you have to upgrade the lights to hps or mh because it looks like it only has a couple fluorescents. Also it has like 6 or something things where the seeds can go in but how many cannabis plants can you actually grow at the same time. All the seeds look expensive but I have come to face that fact what I really want is a plant that has an extremely fast harvest and yields quite a bit.

Hope you post thanks in advance

well i dont know anything about the aerogarden..looks alittle small to me but "exteamly fast harvest and yeilds quite a bit" .... cannabis takes months to grow any way u put it... unless u got some magic soil and large yeild and fast dont mix... if your looking for the fastest way u can get some bud then buy some lights a grow cab soil then look for strains that have 6 week flower time( ontop of the 2+ week veg) and look for medium yeilding plants cuz i dont think u will get to much outa a rushed plant... might wanna look into lowryder ( autoflowering )
