I read that during the dark time of the flowering stage, you should not let any light get to the plants. I assume this even means regular light bulbs that are used around the house. If you want to water the leaves, but want the bulb off and cooled down before hand, do you use a green light to see in the dark? If so, where do you get a green light. I did a search but could not find local place that sold them or listed them on their website.
