138 watt led ufo yield ?

[Loco]

How much do you guys think i would yield off a 138 watt ufo in a 2 gallon pot picking a strain sativa? Im asking to decide what the average yield would be so i can decide to grab 150 watt ufo led Plus i already have a 138 watt so 138+150=288 watts

theres that many variables that you cant really answer that question with much accuracy mate. was one of the first things i asked on here and was told.
"it doesnt matter what lights you got if your feeding them gin"
if thats their actual wattage though id say in a bigger pot you could aim for 5-6 oz with both of them. more light means more bud. from the best of my knowledge with leds any more than 50 actual watts per ssquare foot is a waste. so around 500w per square metre is the top end. can get em cheap though. mars do a 270w for £100 on amazon. probably a lot cheaper on ebay and theyre wicked. : )
