Grams per watt?

Hey guys, another post yet again. :’)
The light I’m running is a viparspectra par1200 which has an actual draw of 540. I have two photo plants under the light, both of which are 100% sativas, grown in coco/perlite with flora trio for nutes. I’m wondering what is an achievable yield off of 2 plants. Is it realistic to expect around 540 grams (1g/w) or would I need more plants in the tent to achieve this?
I’ve also got some fruit/veg plants in the tent, will this effect the yield?
Current pic of the girls below, they’re 5-6 days into flower.
cheers growers

Nope, not in the slightest (unless of course the fruit/vegetables completely overtake the grow space).

...and no, it is not realistic to expect a certain yield. Several things affect this, including the experience of the grower, and how well the grower maintains the environment.

If you keep detailed enough records and have a large enough data set to pick from you could potentially develop a formula to predict your yields.

Damn, that gram per watt talk got me excited. How do they look anyway? This is my first grow and I think it’s going pretty well. Having a LOT of trouble keeping humidity in check though. Cheers for the replies
