okay maybe thats all it is...light should not be a problem, i have 4 42 watt cfls and 1 23 watt....they look like they are unhealthy today though, the leaves are starting to curl downwards and on one of them the bottom leaves are turning yellow...my guess is its too dry...i water them everyday once or twice sometimes 3 times (just a tiny bit each time) and everyone always says that the biggest problem most the time is over watering...does yellow leaves and curling leaves sound like its caused from over watering? its very dry in the cab, humidity is only 25%, and the temp is around 31...im trying to fix that, i keep 2 bowls of water sitting in there to help raise the humidity but it still stays at 25%...im also working on trying to lower the temp...the temp is always changing...from around 25 or higher during the day to the low 30's at night...the reson for that is the cab is in my bedroom so i can open the window and let cold air in when im awake, but need to close it all but an inch when im sleeping so i dont freeze...is it possibly stressing them? i wouldnt think so cause temperture would be constantly changing if they were planted outdoors....any suggestions on how to keep the humidity high and my babies happy is much appreciated
