thank u krunchbubble
dimensions- 120c"m X 120c"m
don't know about 2 X1000w never tried them
i think 3X 600W is better
the hight of the system is 180c"m
so i think 3 bulbs will be better for even light distribution
nice and simple, but not cheap.. i wanted to do this exact system upon my switch to hydro. but the dutch leach bacs are like 17-20$ each. although you cannot beat the reliablity, durability, simplicity. good luck ill check in from time to time.. take care and a boutiful harvest to you. CC
