Just some advice, it's better to plant in small coconut pot before transferring to the bigger pots. Ive never had any problems, and neither should you.
Nothing wrong, it's a good sign. When plants grow they get bigger and taller to get near the sun, your plants are the healthier ones that have enough light, and then some.
Good job by the way.
Ive heard of this before, just because it's on the Oprah show doesn't mean its true. Trust me. It wont cut your bill in half, 1/4 or anything like that. It might save you $5. Ive tried it before. Doesn't work, and not worth the time.
