48 blue cheese in 20 litre pots with 12, 600w lights... yeild ??

[in coco] iv changed my regime alot here so just wondering wot i shud be expecting in terms of yeild per plant, using canna range all thru works out at a bout a fuking grand on feed ;[, so its 4 plants to a light, 600 watt lights wot should i be getting?

Variables my friend.....1 gram-1 pound, somewhere in between

If I had to take a wild guess, growing 4 plants per 600 watt light:

Perfect conditions: 2-3 oz per plant
Bad conditions: 1 oz per plant

In other words, somewhere between 150 ounces and 50 ounces. It's all dependent upon the care you put into them.
