First, give thanks (rasta for thank you:)) for sharing! If the machine gives no smell, I would think this can be useful indeed. But I could not find that spec.
Hydroponic is definitely great for getting better yield and the lights seem pretty decent too. But $2400, and I know the company has to make money, is, in my opinion, a kinda heavy priced.
The 'recreational' user smokes about $600 a year. For medicational purposes, I think many people need to gonna buy 2 or 3 to provide them with their medicine.
If they could lower the price to let's say 1500/1700$, they could hit homerun.. But what is your personal thought?
