Hello,

The plant probably collapsed due to a total environment change. There is no way that the light can compare to the sun. It is strange how fast the little thing died though. I am not sure. Perhaps notanovice could shed a little light on the subject.

Before I go further though I want to say this. Nothing personal, but it is NEVER a good idea to let anyone (in real life) know that you grow. I am sure that all will be well, but it is bad business to let others know. Friends or not. That is the beauty of the internet, you can tell and still no one knows. LOL.

You will be able to tell the light spectrum by looking at the light itself. The light will be whitish/blueish or a more of a redish color. I am guessing that it is probably blue spectrum.

Did you try the hand check method that I mentioned? If you can feel a good amount of heat on your hand when its under the light then the light is too close. I would try to give you a distance, but its really hard to say.

Let me know if I can help out anymore.

Peace
