i am growing 3 skunk plants under a 2 32watt t8 workshop light. i am using 3 gallon pots with 25% perlite and 75% mg seed starting mix. space is not really an issue as long as they stay under 5.5ft, would like to veg for 6 weeks. im still debating on if im going to use nutes or not. what yeild can i expect?
