Hey there... Nice to see someone else growing the Trainwreck. It is fucking awesome!

Sounds like you have things pretty much under control. 18" is pretty close, especially this early into veg. They really don't need all of that light until about 1-2 weeks old. Remember the plants are very delicate at this stage...

You should really do something about ventilation, because those TW's are gonna stink up your apartment. I was growing one plant and thought I wouldn't need ventilation or odor control... my friend could smell the weed walking into my building, let alone my apartment. Now I have my inline fan, cooltube and carbon filter, and I don't have temp or odor problems anymore. If you don't want to cut holes, maybe go out and find a similar sized door that you can make holes into.

Also the tinfoil is useless... how about some flat-white colored poster boards???

Good luck and keep us updated :jointsmile:
