NP, ya HTG is uber cheap, i got one of my tents there. I've never priced out there filters but i bet they'd be real close.
little happy story that helps me sleep at night for all the parents out there
an old boss of mine had a crazy ex that sent the cops and CPS over there more times then i can remember. he had state boys, counties, locals, CPS officials from all over. basically anyone this crazy bitch could get to be shocked and want to go investigate DID and left smiling. he kept everything legit and legal and locked up and it always went his way. the police really never cared. they only ever wanted to see cards then they left. as far as he told me they never even counted plants. CPS tho did some interviewing and all that good stuff and he was good to go. this was before the "No one in the garden without a card" rule and he flat out told the CPS people he was teaching his son how to grow. said it was a trade that will help him someday. the kid said it was fun and he loved learning about plants. CPS apparently was very happy and quit bugging him... i haven't spoken to him in a very long time but i saw him drive by a couple weeks ago with his son in the passenger seat so he's still winning the fight!
