I don't wanna get into this argument but I do want to say this...
There is nothing at all wrong with growing in a 4x4 tent. I started out 6 years ago with a 4x4. Pulled my first 18 ounces indoor on my first run with a 1000 watter. Yeah I started with fox farms soil and the whole ff nutrient line. The bud turned out dank and everybody loved it.
That was the fuel... That motivated me to push harder. I made almost $6,500 off my first run, very little invested.
Second run I pulled the same weight... Kept saving my funds.
Third run I purchased another tent and started growing in straight promix. I then had 2,000 watts of sun.
Then I started pulling 2 and a half lbs averaging around $12,000 plus every 3 and a half months.
Then I was able to purchase a new home and my own land.. No more renting, no more worrying about the landlord smelling and finding the dank.
Now I have a sweet underground grow room only accessible by the meanest of destruction tools or 3 keys.
For the first time I have graduated to a perpetual grow system... I have 4000 watts of HPS and then a separate veg room. My flower room is 18ft x 6ft. My veg area is 12ft by 8ft.
I now will be pulling 5 to 6 plus lbs every 2 months bringing me about $4,500 per lb...
In 3 months from now I will graduate to 6000 watts of HPS and have access to 150 acres of private land to guerilla grow on not including the unlimited access to the thousands of acres around me.
That little 4x4 did a number for me...
Don't judge some one by their setup. You never know where it can take you. And yeah that is the cold hard truth of it.
