I think it was the result of the fan and the way the airflow seems to be a pinpoint and thus I get green AND dark brown/near black. I just think elbows aren't for me because they really do need a stir to get somewhat even browning, and very quickly taste like ass.
I've also had similar issues trying elbow packs where it seems like only the very center of the material actually gets vaped with surrounding material looking almost untouched. To a lesser extent I've experienced similar results with approx. 1/4 or less filled cyclone bowl. I think stirring constantly is a real pia when filling bags (I use bags 98% of the time). My heat settings are generally around 325F to 385F with some occasional experimental sessions going up to 410F - 430F. I always start on slow fan speed until vapor is noticed than increase to max fan speed for bags and "preheat" the unit for 10-30 mins before loading material.
I've tried a few minor adaptations to address my dislike of required stirring with various results.
First thing I did was elevate the unit without blocking the fan intake. There is only a slight clearance under the stock unit possibly resulting in a little drag on the fan. I increased my clearance by a few inches using velcro, wooden dowels and a pair of small "lazy susan" circular bearing sets that have an open center. I can now safely assume any air drag/resistance potentially interfering with the fans efficiency is as close to 0 as possible. I'm not sure how much of a difference doing this actually made but it can't hurt. Worst case scenario is the fans lifespan may increase slightly as it now runs with a slight bit less load - plus - thanks to the bearings my EQ now spins around effortlessly.
The biggest obstacle (as noticed by many here besides myself) to stir-less yet even/thorough/consistent vaping is the design of the cyclone bowl itself - most notably the size of the glass "shoulder" or shelf which supports the flat screen. It just seems WAY too big/wide and severely interferes with even airflow throughout the entire cyclone bowl. The designers had to realize this, but I imagine they used this model/style anyway as its much more economical/faster for the glass producers to manufacture and its easily rectified by ..ugg... constant stirring of vape material.
First method I attempted to overcome this particular issue was to make the screen slightly concave so gravity helps pull more loose material into the direct heated air path at the center of the bowl. Tapping slightly on the side of the unit also helps greatly. As the material in the dead center gets blasted with hot air it dries quickly, vapes and gets slightly "blown" around by the airflow - tapping lightly on the unit assists the removal of this dried/vaped material and allows "fresh" material to fall over into its place thereby starting the cycle over again. By only just ever so slightly "packing" material into the bowl (IMO -unpacked/loose, fine ground is best) and tapping on the unit while filling a bag, I get highly consistent and evenly vaped abv leftover materials.
Still not satisfied and inspired by an earlier posters modification and slight enlargement of this opening to accept an elbow/cup screen, I decided to remove most of this glass "shoulder" and make the airflow opening in the cyclone bowl as big as possible. I took my battery operated dremel with a tile, diamond tip bit and carefully shaved away almost all the shoulder leaving only about a 1/16 inch wide piece intact all the way around - just big enough to effectively support the flat screen. After obsessively cleaning the bowl to insure all leftover glass particulate removal, I tried it out and noticed an instant improvement although making the screen slightly convex and tapping on the unit still helps greatly. OH ...., Just in case anyone also decides to take a dremel to borosilicate glass be forewarned : Don't even think about attempting this without using safety glasses/eye protection and assurances that any glass dust is controlled! Hell, this stuff is tough so full face protection probably isn't a bad idea. Trick to doing this easily/successfully is to use the proper bit, use the slowest rpm speed possible and use water as a coolant or do it under a slight layer of water - this is why I used my battery dremel and not my powerfully precise electric one. Using a dremel "dry" is NOT recommended - It will quickly create lots of very easily inhaled airborn glass/silicon particulates, increase greatly the chances of accidents, overheating, sparks and breakage or even cause sudden shattering. Patience is the key to modifying the opening of the cyclone glass bowl no matter if you use a dremel or do it entirely by hand with diamond files/bits like a previous poster did.
I've even thought about mounting one (or a few) of those small vibrating motors found in cellphones etc to the unit in hopes it would make any "tapping" on the unit (to assist in constant material circulation) unnecessary. These motors are quite tiny, easily available and very cheap. I also have a few other mods I'm trying - most notably different bowl, adapter and lab glass fittings that I found which fortunately are 19mm and fit the EQ perfectly. Perhaps if there is interest I'll post again once I've had the time to thoroughly experiment with this compatible lab glass and have formed opinions.
