Just as a user who looks for the very best and yes I have been around that long I normally get asked to try all the new stuff from most companies. I write reports for them so they keep giving me free stuff. I have worked for Advanced Nutrients before a few times as a consultant as well as the work I have done with Advanced transformer here in so cal designing transformers. (I do have a degree in Electrical engineering). They are working on a transformer where one transformer can power 4000w of hid light and use less power then 2 normal transformers.
