I looked into getting the bllombox but after 9 different retailer all seemed to have the same opinion of how they usually have customer complaints and from thier trials the boxes dont produce anywhere close to company claims they advised against it. I like the hydrohuts and they all seemed to reccomend that route too without me even saying i used them.I knew 2 people who used then and both sold thiers after just a couple grows as the cost and frieght for what the box was capable of putting out wasnt a good ration.What most i was seeing and hearing is the amount of sites the box like the producer has setup is way to many to actually grow bud in. You had to use less then half the sites to get a decent yield from them.Thats the reason I decided not to buy one and if you see one they are very simple to replicate for a 1/3 the cost if you are semi handi..Thats alot of co2 for this little thing for sure.I use 1 20lb co2 tank a month in and 8x8x10 foot room keeping ppm between 1300-1500...They do look cool but i have yet to see one do as claimed sorry
