Haha i get a comment from you when i havent used this sitr in over a year. Not all bottled water has che..micals in it. Most of them actually have it taken out. A lot of people buy RO water and add a cal/mag supplement. And a 150 can grow 2-3 medium sized plants and if it is the ballast/hood combo who in their right mind that knows anything about indoor grows would use that. Pointless and at the very least a 400year watt setup should be used because they are so reasonably priced.. i have a hard time argueing with people that seem like they barely have a highschool education
