Hey I've used this set up about 10 times and I'm not getting the clouds like I was getting at the hookah lounge. I'm getting OK clouds a good flavor but very wispy and I'm drawing for quite a long time. My rig is some China pumpkin with a vortex bowl with 3 Coco naras and one layer of regular renolds wrap with AF loosley dropped in the bowl under the lip. Ice water with the down stem 1/2" under water. I'm thinking I need either more heat or more/less holes in foil. I'm pretty satisfied with the flavor but clouds just are not that dense and fluffy as I would like. Do you guys have any suggestions or tips? I would really appreciate the advice. Thanks
