I recieved an email from (Kurt) @ growers lights in Austin tx for a hlg 600. The email or webpage didn't elude to having a lead time for pre-assembly. It wasn't until 1 day after I placed my order that they emailed stating that they're would be a 7-9 day lead time. Each verbal response has given me a false ship date, I've yet to receive any text or email for shipping or tracking number for my $761.00 purchase. I'll update everyone, but proceed with caution when considering any transactions with growers lights.
