Master kush 4x4 grow

So as you can see the plants have been trimmed up and lolipoped. Been a busy 2 days cleaning up all 3 tents. Each one had a different amout of leaf strip do and this one was the least. The front two got the most with the back left one the least. Hard to reach back there and by the time I was had gotten to this point I was done. So running Co2 is great but ive now had to refill my tank ones a week. At that rate by the end of week 6 I'll have spent $200 on Co2. Now I know from past grows and from research that adding Co2 to grows helps to increase your yeild by 50% but if I don't get atleast 1.5g per watt this grow (720g) I'm going to start looking at a different light. This one has honestly beenone of the worst performing lights I've used so far. Yes it's nice the plants can get so close to the lights, but so far the best I've done with this light is 1.05g per watt. Nowhere near as good as I've gotten with lights like the Spider-Farmer SF-4000, the gavita 600e hps, or the philzon 2000w cobb light. If I do switch my light I already know what one I'm going with. The grandmaster LED torch 480. Samsung Evo mint white with 730nm far red, and still 480w (don't have much more power to give). So far everything I've read about this light company is amazing. Highly recommend checking out. Well that's it for this last week so peace growmies ✌️
