I just planted a 20 gallon high tank. It's cycling, and won't have fish for a couple weeks. The water temp is currently holding at approx. 70 degrees F during the day, and dropping down to low 60s overnight. Should i bother to hook up a heater, or will the plants be fine in cooler water? If it does need to be heated, what temp is optimal for plant growth?
Thanks!
