hey i just wanted to know what kinda of systom is good for biginers and how many plants i can grow in a closet i didnt ask how to grow it and what a ph is
Four plants is probably a good number for a closet grow, and I guess Ill throw in some tips on a grow setup for you. Well soil is a good start. 50/50 Promix and Perlite shouldn't let you down. Then there is PH, you want to maintain a stable ph of 6.5 in soil, which is slightly acidic. This can be controlled with a ph control kit, which includes testing supplies, as well as ph up and down to adjust your ph accordingly. You will probably need to add ph down to your water, and ph up to your nutrient solution, as organic nutrients tend to acidify the water they are added to. Always remember to test ph AFTER you add nutes to the water. Then there is nutrients, for a beginner I would go with a nice full spectrum hydro-organic fertilizer such as pure blend pro, you will need a vegatative fertilizer and a bloom fertilizer, pbp makes both. Do not fertilize for the first two weeks of the plants life, then feed every 3rd watering after that, gradually increasing feeding strength from 1/4 of the recommended dose all the way up to full strength when the plant can handle it. Now lets talk about lights, most beginners start with cfls, daylight spectrum for vegatative growth and warm white spectrum for flowering. The more and the higher the wattage the better, heat will eventually become an issue though if you add too many. That takes us to ventilation, you will need some sort of intake and exhaust in your growing space to provide fresh co2 and to simulate wind for strong stems. This will also help maintain a stable temp, somewhere between 70 and 80 would be optimal for growth. Switch from a 24 hour photoperiod to a 12 hour photoperiod to induce flowering, this is when the plant starts to grow buds(but only if it ends up being a female, males are worthless). Keep in mind the plant will grow to be 2-3 times the size it was when it started flowering, that means if you want to harvest a 2 foot plant, flower it at 8 inches.
Like I said there is way too much info to post at once, but there is some useful tips in there for you
