4 lbs every 3 months with 3600 watts?

sup guys so been growing for about 5 years now indoor and out and just looking for some feedback to see if my estimations are within reason. Gonna have a decent sized grow room about 9x6 with (6) 600 watters each covering a 3x3 area that will add up to 6 plants in there all 8 week clones from harborside. They will all be in 20 gallon tubs with FF and FF nutes and going to scrog them. Will be vegging for 4 weeks then flower for 8 and planning on 4 harvests a year like clock work. Trying to get AT LEAST 9-10 ozs per plant.....basing this off of this grow:https://www.icmag.com/ic/showthread.php?t=12653&page=1&pp=15........ where i know its hydro but he started from seed where mine will be clones so i figure the veg is about the same wince hydro has little effect on plant size while it flowers and this was a 400 so i figure my grow should pull an easy .45-.5 grams per watt while this guy managed almost 1 gram per watt. Input? I think I'm being more then reasonable in the .45-.5 gram per watt....should actually be able to do better but i hardly get more then i estimate haha

With the right strain, it's very reasonable. But 1) if you want 9-10 oz per plant, figure at least 6-8 weeks veg, and 2) you are assuming everything will be perfect the entire grow which rarely happens (anotherwards no bugs, diseases, deficiencies, stresses,etc) and 3) most heavy yielding strains flower longer than 60 days to be done properly.

Ok i've thought about this before myself. There are so many variables man. IMO if you wanna get 10 oz a plant you gonna have to scrog for sure. And probably find a bushy strain or FIM all your plants.

Again a lot of variables to how well your crop will turn out. You'd have better chance getting 10 oz a plant outdoor, most i've pulled off 1 plant indoor was 5 oz, with scrog all in 5 gallon pails.

Im not saying you cant get a g per watt, but i cant see you doing it your first few tries maybe not even your first dozen tries.

I wish you the best of luck.

Think your looking to far into it... know many people with 3k watts over 12 plants in same space pulling 4.5 lbs every harvest with 4 week veg. Perpetually. No training at all. They just let it grow and lollipop. Lucas formula and 4 gallon titan system. Pretty much run on its own.

Sounds do-able for sure with everything dialed in...
