How did I do?

I am growing White Russian from clones using 600 watt HPS. I use Fox Farm nutrients and Sunshine Mix # 4. At 4 wks of veg (under t5 fluor.)and 8 wks of flower I netted 34.6 grams of timmed and cured bud. AT 5 wks of veg. I netted 33.8 grms per plant. ( one plant only produced 15.6 grms). At 6 wks of veg I ended up with 54.2 grams per plant. Is this about average or do I need to try harder?.

You can get larger yields with that strain so i would try harder. But with a 600w that isn't bad
More watts =more bud
go for the 1000W and you will get even larger plants

i know i like big buds ^_^

Well...that really all depends on what size pots those were in. if they were in one gallon pots...outstanding. In 5 gallons, not so hot. Even when we do great, we should still try harder next time. To really get the most of yout plants make sure to never break their momentum...if you can do that they will optimalize, and thats really the best you can hope for.
