Printing tall thin objects with ABS is a challenge, which takes skill, know how and a very well dialed in printer to do right, and oftentimes an enclosure is required to get the proper results.
To start with, White filliament in general is a pain in the ass to print. whatever pigment they use to make it white seems to require either a 5 degree hotter than normal or colder than normal temperature, with no rhyme or reason as to why. Generally for better layer adhesion on tall thin ABS items, you are going to want to go hotter. With a Taz 4, you are limited by the buddaschnozzle to how hot you can safely go. 240c which is the minimum to prevent those splits, is about failure temperature of the Buddaschnozzle. You should strongly consider getting a hexagon or similar hotend at this point (a hexagon would let you upgrade to 5 firmware without needing to change anything else, just add a PEI sheet if you haven’t already) . You really want to try it at 250c if you can get there.
If that doesn’t do the trick, try turning on the Skirt option in your Slicer. This will create a 1 filliament wide container surrounding your print and following it up, starting at the edge of the Brim. What that does is act as a wind break and thermal insulator, trapping warm air next to the print and preventing it from splitting. You can manually extrude such a shield into a design when making it as well as needed. If you can, thicken the walls of the part 2-3mm, that will reduce the splitting considerably.
Skirt wastes alot of filliament, so many people opt to just flat out build an enclosure. Since you are in a basement, thats probably going to be your best long term option. There are a couple people selling enclosure kits in the hardware development section of this forum, or you can find several plans for DIY ones in the “all of the mods” thread https://forum.lulzbot.com/t/comprehensive-list-of-taz-modifications/1971/1
Other things that will improve layer adhesion include stiffening the X and Y axes, and removing the bow in the rods. There are various methods available to do that.
