You obviously are impaired.
He spent FAR more than that on his nutrients alone. It kills me how people spend hundreds upon hundreds on tents, medium, nutrients, testing instruments, all kinds of bullshit...then they get cheap on the most important part of it all, the light.
It's like building a race car: He went out and bought a bullet proof bottom end, best cam, lifters, rods, all of it. Top of the line heads, exhaust and then at the very end he gets cheap and puts an old, outdated, piece of shit carburetor on it.
He would have been better served to wait the 4 weeks to save up the money for the decent light. After all, it would have doubled his yield and in so doing paid for itself 5 times over.
It makes absolutely ZERO sense at all to do that.
