How cold was it and for how long? That sounds insane. My night time temperatures have been dipping into the high 50's recently and it's been tough managing that also. Just keeping the day time temperatures over 75 has been a bit of a struggle as of late.

Glad it all worked out for you. My growth rates are suffering, I have plants that are 6 weeks old and look more like 4 weeks old. Hell, I have this one plant that looks 2 weeks old. Those low temperatures are a bigger deal than I'd thought, I'd been trying to keep them low for my flowering tent and the veg tent suffered as a result. Just adds time... It is lame but a learning experience.
