:yeahthat:cadlakmike1 said:I personally use a MH conversion for veg and a HPS for flower. Far less lumens are needed when vegging so it is more important to get the correct spectrum. Not to mention the fact that the bulbs you are comparing both provide enough lumens for that space. While the HPS would work the MH will promote shorter, bushier, more compact plants and will help limit the stretch. Again, use the MH conversion for veg and the HPS for flower.
