Where do you get your bulk heads from?

[Delphinus]

Pisces, Big Al's, Riverfront ...

You can also get bulkheads from Bumper Crop (hydroponics store) for about a fifth the cost at LFS (about $2-3 each). Although, I'm not sure they are suitable for use with a standing pipe. But if no standing pipe, they should be fine. Speaking of Bumper Crop, they sell Mag Drives at half the price at LFS. I got a Mag7 for, oh shoot I don't remember exactly anymore, but it was in the order of $70-80. You can also get replacement parts for Mag Drives at Bumper Crop. I needed a new impeller, none of the LFS would help me except Pisces, who had to special order the part. I then went to Bumper Crop on a unrelated matter, and found they STOCKED the impeller and it was like $5. I thanked Pisces and got the part from Bumper Crop instead. :D
