Last week we had a cold snap and I lost a youngster that was out in my grow pen. I have 2 heat lamps on them, but this little one must have gotten pushed aside. Now we are expecting temps to be highs in the 20's! I wont make that mistake again! I just went and bought a huge plastic tub and placed it in my spare bathroom tub. Looks like I will have teens in my bathroom again this year! LOL So please learn from my mistake and bring thoes little ones in if it gets bitter cold! I wouldnt want anyone else to feel as bad as I did.
