Hi Brian: Nice to see you're back home. Your seedlings are unusually nice and green for this time of year and for being as far north as you are. Seems whatever mini micro climate you have around your apartment certainly allows them to grow a long time. That's good. I always say--let them grow as long as they want to, or as nature provides. The longer they grow, the bigger the bulb will get. At some point in the near future, the leaves will freeze and dry up. This will not adversely affect the bulb in any way. Just make sure your soil in not overly moist. Once the foliage is gone, you'll notice your pots will stay moist much longer, especially as temperatures continue a downward trend. You'll still have to come up with something for safe cold storage over winter tho.
