I know that this question has been asked many times but I was just wondering. I am using a 400 hps and I am using Fox Farm soil. Like 3 or 4 plants. I got seeds from Nirvana called Misty. Any pros out there have any ideas on how much I could expect to yield??

Depending on how long you veg her, and what nutes you feed her. it can differ. based on nirvana she yields decently
From Nirvana:
Yield (Sea of Green on one m2) : 500 (i believe thats measured in grams.) but i dont know what the sea of green on one m2 means.

500g per square meter of floor space........I could be wrong though

Depends on how good of a grower you are. I just screwed up most of the seeds I was germinating. Three did make it but I forgot them in the cupboard. LOL ... Not the first time I've done this.

with 4 plants under 1 400hps thats like nearly 15000 lumens per plant.with optimum conditions youWILL get an excellant yield but NOBODY will be able to give you dry weights per plant.

I'll take a guess. With four plants under a 400 watter, grown to 12" before the switch, you'll end up with four plants that are 24 to 36 inches high at the end of the flowering cycle and will yield about two ounces total. Now, that's dry weight ... all manicured and cured in jars. If you are a really skilled grower, or growing larger plants, then the yield will be larger.

you can almost triple that on 1k hps

With 3 or 4 plants, I think 7-8 oz. would be a generous yield...............

Well, I know of someone who grew out ONE plant in an empty walk-in closet using one 1000 watt HPS and harvested around 2.5 pounds! But were talkin' apples and oranges here. The plant was so big, he couldn't get into the closet to change the res anymore ... so he had to cut her down. *lol*

russ0r guessed my beast would produce around a pound of dried bud based on its size, which was grown indoors off one plant with a 600hps

but then it is 5.5 foot high and about 3 foot wide at its widest point
