yea 4lt size much better deal but the amnt of nutes still seems high. i read med-mans site and hes def done some tight shit but if ur just starting out u may want to balance his techniques with something more modest. i guess what i mean to say is if ur tryin to b a chef and just starting out, make sure u know all the variables when trying to master an advanced recipe. he does all kinds of shit i have yet to learn and prly knows the best strains to use with each situation and/or nute combo.
