How many vegies can I yeild w/70w HPS?

How much vegetables can I yield with a 70w HPS?

1/2 oz 1 oz 1 1/2 oz's dunno depends what nutes you use where the light is what strain etc

im im using fox farm nutes have the light 4 or 5 inches away. Havent strted nutes yet still too young. t here is only 2 plants so I thought 70w would be enough. Would I see a significant larger final outcome if i get more w's?
?

With 70w you will have spindly, thin plants with puffy buds and you will have a small yield. Well, OK so it is POSSIBLE for you have a decent yield and have some compact buds but it's not as likely to happen without a little more light, say 150 to 250w's would be better.
