uh anyway.... how long does it exactly take a hydroplant to grow under favorable conditions? by favorable i mean floros and fish water as nutrients, and of vourse proper ventilation!
Depends on the type of plant you're growing. Couple of weeks to germ the seeds, couple of weeks for vegetative growth and then 44 to 60 days of flowering. Block off 2 1/2 to 3 months of time.
