See, the thing is, your definition of a "good strain" is dependant on A) your situation (grow room size, odor control, temperature, ventilation etc.), B) your "weed tastebuds" (what you like your weed to smell and tastelike, bag appeal, etc) C) what is a more important trait, awesome yield or awesome quality.
Most people try to be pretentious "weed snobs" and say it's all about quality. It's just flat out not all about quality. The potency of the weed in my opinion is not the determining factor. The yield is not the only determining factor either, but some plants sacrifice so much in yield although they are fantastic, they are poor producers and in my opinion a waste of time.
On the other hand, some plants produce a shit ton of worthless bud. This is VERY few and far between. Lowyrder is that way, but they've now crossed it so many ways you can get a lowryder that isn't completely worthless.
Most of the garbage, low potency weed you get isn't strain related. It's not even usually a direct cause of the plants growth being poor. If the plant grew the buds it was grown okay. It's generally the harvest, drying and curing that went terribly wrong.
If you grow Big Bud properly and you harvest, dry and cure the bud properly it will produce ample potency bud and LOTS of it. You will get more overall THC out of your crop than you will by going higher potency lower producers. It's also a forgiving strain and should be fairly straightforward to grow.
So my overall review of Big Bud:
High Yield and Production
Medium to Medium-High potency (Medium-High if you're lucky, do everything right and happen upon a real strong plant).
Easy to Grow
Can be unwieldy if you are growing in a small space.
For your next grow, try to consider these factors when choosing a strain.
