Alright man, heres the deal. You're trying to double your space, you're going to need to double your light. If you're not prepared to do this all the way, then you're essentially just downgrading to a larger tent to grow double the amount of shitty, larfy, light starved bud. If you cant afford to do this correctly all the way, this entire endeavor is a waste of all your money and resources. Nobody is telling you not to buy the blurples because we dont want you to succeed, just the opposite. You will be sorely disappointed with the results, and that is a promise, nay, a guarantee.
