Welcome to the community! Please don't be afraid to ask questions. We were all beginners once, but thanks in part to the advice of those in this community we've been smoking the freshest and finest of weeds!
You should do some research on autoflower vs photoperiod before you commit to an auto grow. Not at all saying autos are bad. Just saying you should look at all your options.
Alright , not much experience but personally but it is the route I've started with . I use a single 300w dual spec CFL and for a single plant i rate it quite highly . Currently doing an autoflower on it @ day 50 from seed and my CFL is doing me proud so far
