So I got a coconut seedling (Green Malayan) a while ago and it died pretty much as soon as I potted it up. I tried once more with a Jamaican tall. I potted it up really carefully and put it in full sun. The next day the frond was shriveled up (luckily, it still had it's first spear, which was very very thick, so it made it) so I brought it inside, kept the A/C to a minimum to make sure it was 80 degrees, the lowest it got was about 75 at night. I put a humidifier next to it, and a 100 Watt equivalent full spectrum HD Fluorescent bulb about a foot away. For a while it hovered with no growth. It looked like it started up yesterday, so I began recording the growth. It's at 1mm of growth per 3 hours on the fried spear with a new green one starting to push out. Hopefully it survives our 10 hour move down to Bradenton (in 2 weeks), where it should thrive once it's there.
