The release of the new units aren't or about 5 weeks and I'm a week or so away from putting my 5 plants into flower and after stretching there's no way my single 006 will be able to handle all of them for that long. Ideally look for 2 of the ms0004's if theres a place with stock or someone selling there's id like to know, iv already ask GN and they just steared me in the direction on the new unit as the old ones are now discountinued
