Dude,, not gonna happen. Space is too small. Pleeeeese dont veg for 40 days. In that space with 10 plants, veg for 14 max, You need to remember ,indoor plants will usually grow 2 to 3 times there height, hen the light cycle is changed to 12/12. If you veg 23/1 for 40 days, you will end up having to cut them down and start over again, because they will end up growing right into the light, burning and not yielding a thing. If you want a pound a plant you need to get out of the closet and into a large bedroom. Even then you will need at least 5 more of those 1000w lights. My professional opinion is veg for 14 days max and hope for a pound total.
