K, there's the Lid, not so hard when ya use the "Extra's", lol....

Now it's time to get the main Jug ready, nice and easy here, only 3 holes!
First you gonna want to figure out where your Pump Hydro chord will come out the Jug....this is where the 3/8 drill bit comes in, drill your hole and make a slice with the Knife to the hole to allow chord placement.... i suggest about 2" down from the top on the corner closest to the plug when set in your grow room, just some forward thinking there...



Thats where i placed mine, i sealed the slice with reflector tape on the inside, but you can use anything, just think about future pump changes tho....

Now you gotta drill 2 x 7/8" holes for the fluid level indicator hose and fittings, one near the top (make sure it's lower then the lid will be) and one at the bottom.... i suggest you go and get these little rubber insert for the hoses and make sure the drilled hole is just a hair smaller so when they are inserted and the 1/2" 90's forced into them, they will be totally leak proof.... this is a spot you gotta be carefule, make it tight and you will not need glue or silicone....
