Yep, you definitely need to control that lighting! Lights on for 10 to 12 hours is usually OK. If you watch, you'll see some of the plants start to close up after about 10 hours (the rotala, probably).
A lot of welding supply places do refills. You may need to call around some of them to find out which do it. Even if the place you call doesn't, they probably know who in town does. |
