Yeah. Buds range in different sizes and shapes. It all depends on how much light they're given during growth. So giving you a picture of an undried bud, wont do you much good.

With small wattage lights during the growth of the plant, chances are the buds will be small, but good. The overall yield should be about 2-3 ounces with a weak lighting system (CFL).

And with HPS and HID lights, around 400-600 watts, it's quite possible that the yield could be in lbs (pounds). Or high-number ounces, such as 5-6 ounces.

It really all depends on the lighting, and the nutes you feed the plant once you see it start flowering. Buy a fert. with a high middle number (Phosphate, if I remember right), for best results, during the flowering cycle.

The hairs range in size as well. I've seen a plant with hairs a half an inch long, and i've seen another with hairs an inch and a half long. The hairs really don't matter much, to be honest. As it only matters that your plant actually HAS hairs. Thus, confirming its female gender.

Determining if your bud is ripe or not can be done 1 of 2 ways. Checking the trichomes, or checking the hairs.

If the trichomes (crystals) all (or atleast 70%) become opalescent, then the plant is more than likely, ripe. And it's time to harvest. Once you see the crystals turning reddish, then immediately harvest. As the THC value is deminishing. This method is kinda tricky to find out, and takes rather a magnifying glass, or a microscope. Unless you've got a lot of patience on your hands, and enough money to afford rather a microscope, or a magnifying glass, i'd go with the next method.

The hair method. Simply check the hairs. If 70% of the hairs become amber in color (a brownish-red color) then it's time to harvest. This is the method most commonly used by growers, and it delivers pretty good results. If you don't have alot of time on your hands, go with this method.

When harvesting, cut the bottom of the stalk, and trim/pull the large fan-leaves off your plant. Then hang them (the buds) upside down (to promote flushing) on a clothes-line, in a well insulated room, for about a week or two. Checking them daily, to make sure that they're not growing mold.

After about a week or two, they'll then be ready to smoke, eat, vaporize, etc.
