>>477875Here's what I believe to be a large Milkweed Bug with a very pretty morph
>>477878As long as you have decent weather outside right now they're probably fine, but if it's still quite cold during the night they may just halt their growth until it warms up, which could stunt them. If I were you I'd just raise the light until the night time temps warm up, and hope they don't get too leggy. But then again, they're sunflowers, how leggy could they be?
