I don't know. I don't have a scale. Volume wise I suspect I will get 3-4 500 ml mason jars when dry. That;s what I got off my 2 Norther Lights.
I might have more this time though because I used 8 t-12 48" tubes for my first grow. The buds were great but when pretty light & airy when they dried. I switched to the HPS & these buds seem more dense so although I expect similar volume, I suspect the actual weight may be higher.
I only grow as a hobby for my own personal use. I have never gotten a scale because then I could be busted for trafficing or intent I think.
Although, if the police busted me it would be a sad day when my 2 little plants in the basement would be a priority to any police officer. But better safe that sorry.
Here's a picture of my first grow & then one of this one. I think this ones more. As you can see I burned the hell out of my first grow. Actually, now that I look at them side by side I think Im gonna get a fair bit more with this one.
