Re: NO Clouds , Less Smoke = ??
Sounds like he's using quick lights,
First off make sure you are LOOSELY packing the tobacco, and the foil is tight as a drum.
Once you poke your holes (a bunch of smaller holes would be a good starting point) and your put your coals on, if it's like a 1 and a half inch round QL, try cutting a few in half and putting Three halves on the edges of the bowl, of course make sure their glowing hot first, and let them cook the Tobacco shisha for a while, don't get excited and start puffing away.
It might just be your heat management, experiment with the number of QL halves on the bowl and see if that works, and of course switch to natural coals, like Coconara's, Ql's will get the job done, but in the long run you'll want a good quality natural coal.
If all else fails slap a windcover on it, lol XD
