Im not sure of any good commercial pipe appart from the vaporgenie.. Maybe you should look into building your own like the Inspirator MKII ?   The most important is to use conduction (controlled hot air, with a buffer between fire and DMT), instead of conduction (like meth pipes or others where the hot pipe material is what heats up the dmt ) or direct lighting which usually burns dmt

Sounds great about planting stuff, good luck, let us know how it goes!

Btw u didnt mention your psychedelic experience
