Pepper plant do not get very large but they do get bushy. So it is recommended to transplant with a foot in between the plants. If you are planting on black plastic, it is important to make the hole large enough to prevent the stem from touching the edge of the plastic which will burn the plant. Planting too close will cause a rust on the fruit and leaves. It is highly advised to stake your pepper plants. If the stems fall over, they will snap or pull the roots up.
Harvesting peppers of any kind is very easy. Simply spot a pepper of preferred size (bell pepper, softball size). It is also best to make sure the fruit lengthens before harvest. To harvest, simply pull the fruit in the opposite direction of the stem or use a knife to cut right above the pepper. Make sure you do not cut or pull any leaves off the plant. One very specific aspect of harvest is to harvest in the morning. Peppers tend to lose their taste and nutrition if harvested later in the day.
Snack Box Variety
The snack box variety to very convenient. Because the fruit is very small compared to bell peppers, the plant will produce more at a time than large bells. They taste as sweet as a bell pepper and are easier to bring to color (large bell peppers will take a long time to mature into a color other than green). Harvest when the color is starting to show or is completely turned. If you harvest when there is still green, it will continue to turn after harvest.
