Hello my name is trillyen, and i just joined this site today!!! Although im about to enbark on my own home growing expierence, i have before when i was younger did a home grown experiment, but never to actually have a plant fully flower like ive really been wanting to see this brings me to my question, i have always wanted to grow hydro ponically but im not sure how exactlly its done i plan to flower my plants in a aerogarden, but i would like to keep the mother and father plant or plants in a home made rubbermaid diy system what i dont understand is the plants roots completley submerged in a water solution??? do u ever have to change the water??? i would think so cause dosent the plants use up the nutrients in the water??? IF the plants arents completley submerged in water is that what the pumps are for to spary the roots that arent in the water every 3 or 4 hours where in the hell do u get those rockwool grow cubes from cause lowes home depot or menards dosent even know what they are.. Im sure i have more questions but im guessing these are my main concerns and after getting these answered im gonna start out on my indoor growing journey I was wonderning what r some of your guys reason for growing indoor is it mostly for personal use or is it for profit just wondering I was also thinking that the reason the government dosent legalize weed is because they wouldnt make any money off of it, every one would just grow there own right??? Thanks for your time ladies and gentlemen!!!!
