I actually emailed Liht for a minor typo on that web page, LongNDeep2. It was this passage:
"Liht has proprietary technologies which will eliminate contaminated product and will ensure a healthy harvest. Photomorphogenesis is the process by which a plants growth and development is controlled by light manipulation."
Told them "plants" needed an apostrophe to make it a possessive: "plant's." Also told them they're great and to keep up the momentum!
