So I did a little more research on seeds and prices, and found a nice site that will give me 5 Lowryder #2 feminized seeds for around $50. Not just that, but the same site also sells a brand I had not seen before, an Indica/Sativa hybrid of two strains, AK-47 x Lowryder #2. This means that it will have the potency of AK-47's strain but with the auto-flowering, fast-growing properties of Lowryder #2, making it the ideal choice for me in a stealth grow.
So I plan to buy 7 AK-47 x Lowryder #2 seeds and 5 Lowryder #2 seeds, both of which are feminized. AK-47 x Lowryder #2 has an average outdoor yield of 20-50g per plant (multiplying that by 4-7 plants, assuming some die in the process) and Lowryder #2 has an average outdoor yield of 12-15g per plant (multiplying that by 2-5 plants, assuming again that some die in the process, no telling really)...I'm looking at a rough estimate of 6-8 ounces.
Now I just need to get some organic potting soil and some peat moss for the site, and I should be good. I still have the flowering and vegetative ferts from last year's failed grow, so I'll just use them again. I'm assuming, however, that because Lowryder #2 is auto-flowering, it won't need much or any vegetative (20-20-20) fert, but I don't know enough about auto-flowering plants so I have to read up more.
Suffice it to say that I have much more research and work to be done.
