good luck with the water.

ideal temp is 78F, but this can vary without much harm. not too low or high though as this will cut photosynthesis.

first off use things to raise your shorter plants. you want an even, continous canopy.
then stick your hand under the light. you should be able to leave it there for 5 seconds before you have to remove it because of heat. back it off just a bit. this is a good height for your light.
