bro.. my advice is to get on that train asap.
it can be as easy as using jiffy pellets/rockwool cubes, or a glass of water.. or as involved as aerocloning. but if you don't acquire that skill, then you're starting from seed/scratch everytime.
which means, unless you're spending the money on f1's or fems, the variation is going to drive you nuts.
from seed, if you want to keep yourself in smoke, you need to;
*start at least twice as many seeds as you need. (m/f ratio)
*start them min 8 wks in advance.
cloning requires both of the above, (take twice as many as you need, and start them 6-8 wks in advance,) but at least you know what you're getting in advance.. sex, octaine, yield, stone, taste, smell, finish time, and a mature, fully expressed plant. (an indoor plant bloomed @ 7wks from seed, will never
be as strong, or yield as well, as a clone from a 6 month-25 yr old mom.)
i haven't checked, but if you can't find the info here, there are other grow sites with plenty of info. (compassion corner or planet ganja, among others.)
read and experiment.
my only advice regarding cloning is; domes and rooting hormone are way over rated.
