Amazon Fire 7 deals. The 7-inch version of Amazon's latest Kindle tablet. Sitting at the budget end of Amazon's Kindle tablet range, the Fire 7 is the same as the HD 6 only slightly bigger. In terms of a content delivery system, the fire 7 is absolutely perfect.
In general for most vegetables you want at least 12 inches deep, for tomatoes and large squash 18 inches deep, for herbs and small flowers 8 inches deep. Longer and wider is always better because the soil stays more evenly moist (up to 8ft long x 4 ft wide for raised beds and 8ft long x 3 ft wide for boxes).
This depends on how tall your sprinklers are. For most 4 inch pop-ups you will need to dig trenches about 9 inches deep at the sprinklers. To know for sure how deep to dig, assemble a sprinkler on a fitting and measure the height from the bottom of the fitting to the top of the sprinkler.
