4x8 2 600w or 2 1000w. Are magnumxxl worth investment over htg reflectors hoods

im moving up to a 4x8 grow tent. I grow in soil and dont and have never have done scrog. I grow taller trees. I already have a 600w, should i step up and get 2 1ks or just another 600w. Is it worth the difference in price. Also are the magnum reflectors worth it over normal air cooled htg hoods. All advice is appreciated.

i love those 1000 watts lights but for 4X8 i would say 2 600 watt lights should work wonders

and get them air cooled vortex fan sucking the hot air out

ok how many plants would you run and what style in that set up? Do you guys use air conditioning in addition to closed light air exhaust system? Are magnum reflectors worth it for that size tent or should i just save my money?
