There are lots of ways to tighten skin after you lose weight, and many reasons to do so. The loose skin can come from pregnancy or even just dropping a lot of weight at one time. While you might be at your goal weight, you might still feel bulky, and the culprit is loose, sagging skin.
Petunia seeds will germinate in 6 to 10 days, depending on type & color. Pink & White 1st, red last. Combine damp-off with water & let sit for a day to get to room temperature. Fill your seeding tray with damp soil mix. Water with warm water & let sit for a bit.
Place the petunia seeds beneath fluorescent lights. You will want the petunias to be at least four to six inches beneath the light fixture. Make sure that you put a timer on the lights so that they are lit between 16 and 18 hours each day. Raise the lights as the seedlings grow, so that there is always that four to six inch space between the petunias and the lights.
