My best friend Jana uses blown glass bulbs for her houseplants so I figured I would try two of em out myself.
The Lilly has taken well to it while the Chinese Lanterns outside have sucked up half the bulb already. Not sure it will be a good solution for outdoor plants with the heat but worth a try.
Sunflowers are well but had to fasten the plug at the bottom of the box as the soil registered bone dry with 24 hours of watering them. Might have to check these guys every morning. So far so good, but some yellowing on two seedlings. Nothing severe but it appears to have happened to leaves still stuck in the seed pod which I picked off today.
