<p>I just raised my light, and turned the timer down to 12 hours on. I'll be putting in some new lettuce sprouts this weekend, and will take the overgrown ones out one at a time over several days so my nitrates don't climb to high. Thanks you guys!</p>

<p>Dont worry about the water temperature, thats not the reason why your seedlings are bolting. You said that you have a 250 watt metal halide bulb place 24 inches directly above. Thats why your lettuce is bolting. When i mentioned 60-65F, its refer to the air temperature not water temperature. Hang the light up higher and give your crops less light (length). Lettuce is a long day plant. Its a guess, the length is around 9-12 hours. Keep it around that. Well, just give it a try.</p>

<p>The issue is too much light. I've found that excess lighting caused my lettuce to get really long stems, and I even had spinach that went straight to bolt. How many hours per day are you giving?</p>

<p>I have it set up in my basement. I'm worried the bacteria won't keep up. I also need to add another GB, so I'm starting a small raft tank. I just found the temps for bacteria in Sylvias book, and The growth will only decrease by 50% at 64 degrees. The fish not eating is a concern though. I posted on that in the Fish forums. This is my first set up, and I only lost one gill in 3 months.</p>

<p>Matt, you have water temps of over 70 degrees now in Wisconsin? Is this indoors? I live in Louisiana and the highest my water temps have been lately is 61, and that was a pne time reading.</p>

<p>I dropped the temp by 2°, from 75° to 73° over several days. My bluegills have all but stopped eating for reasons unknown to me. As for the lettuce, it is not sending up seed/flower stalks, which would confirm the bolting. I'm still waiting for the seedlings to get bigger before I introduce them to the system. After that I'll take out some of the tall lettuce to allow more light. Taking too much lettuce out now will cause my nitrates to climb to high, and who knows what…</p>
