 actually there is no restrict of growing crops at your home. but you should take care of the plants with full measures like giving proper irrigation, keeping at sunlight,giving manure to provide nutrients to the soil. 
but if u are planning for any harvest than too many crops may not give any output. it is all about proper balancing amount of plants to achieve out goal or yield.
 you should plan on growing 1-8 plants.f you grow more than 8 plants under a single grow light, chances are you're hurting your yields by not giving each plant enough space to thrive.
