That's a nice light fixture, not overly pricey too. I'd go for it. I can't answer whether you'll be able to grow everything, but surely it will do better for you than PC
, buying a purebred St. Bernard and a purebred English Mastiff, only to have them mate and produce mutts, is like buying two extremly expensive fine wines, and them mixing them together and throwing some beer in there as well. You're paying for everything you're not getting.
Still, you can rest assured that hip displaysia, cancer, or other problems with inter or in-breeding are not likely to be issues.
Catatonic, I don't like it when I see dogs caged or chained for long expanses of time (most of the time) outside. Sure, they're dogs and can handle it but it just seems wrong to me. Outside dogs wouldn't smell as bad or be as hairy or dirty if they were kept inside, so it's sort of tautological reasoning: I keep my outside dogs outside b/c they're dirty and smelly. Of course they are! You keep em outside! Just my opinion though. Ironically, I do agree with the annoyance at people treating their dogs like people. Clothes are for humans people!
FYI figiwigi, I hope you have a garden b/c with all that dogfood you'll be buying you'll have plenty of fertilizer as well!
