I think it's more of a goal- I would say you could def get 800g, and a key is do-able but difficult. I just like to have something to shoot for, lets you see if you are improving.
ps, this may be of some interest

Well, I have now realized I will only be able to fit 9 plants in my area. Unless I go for two plants per pot and I don't know if that's such a good idea. I am in the process of sexing now, I already chopped 5-7 males and have 4 females in the pots.
So 9 plants @ 1000w HPS
If I can pull 800g off that, I'll be a very happy camper. I'd be really happy with an lb to be honest.
Here's what I'm looking like as we speak, you can see my 4 fems in big pots and the others are still waiting to be sexed. I have room for exactly 9 pots. So anything over 9 females is going to give me the option of throwing them out, planting them together two per pot, or putting the extras outside someplace.
