Let your water warm up a bit before you pour in on your plants!

Put your plants on foam board to keep them from sitting on the cold floor

@scottyreal as I just took a 3/4” piece from work, the left over from insulating, funny you say that and was going to reconfigure the tent putting that under the spill mat.

Get your plants off the ground. Put them on plant stands.

My grow room is part of the garage and the air conditioners face the big car part of the garage and they keep it warm enough in there for them (the A/C’s) to keep running. It’s about 50° warmer in there than outside temperature. Even when it’s -30⁰ My air conditioners kick on. When it does get that cold I do have to add a little bit of heat to the garage so the air conditioners will work. But most of the winter they do work without help.

I’m now running my lights at night. Helps a lot, and is cheaper!

I’ve seen intakes connected to the ductwork if your a homeowner. They use it year round to heat, and cool.

I’m in Minnesota, I insulated the hell out of my grow room. The outside walls are about a foot thick, The ceiling has about 36 in of insulation above it. The wall facing the other part of the garage is a regular 2×4 wall with R-15 in it. This allowed me not to really worry about outside temperature too much, I am running a sealed room too.
My garage is detached. I ran conduit from my house to the garage and I ran a heat cord on a thermostat through the conduit along with two 1/4″ tubes for R/O and now just straight tap water too. I have made this so if the heat cable does fail I can pull the tubing out of the conduit, even in Winter, and put new water tubing and heat cable back through and be up and going again in hours if need be, if that ever does happen…. Or should I say, when that happens. I’m also reclaiming all of my condensed water from the air conditioners and the dehumidifiers. So if I do have a failure I usually have a fair amount of water stored too.

I’m in Minnesota and when I was constructing the grow room, I built it with weather and mind. It’s in a garage and it shares a wall with the inside of the garage. The three outside walls of the grow room are about 12in thick, above The ceiling is about 30in of insulation. The wall that’s shared with the rest of the garage is a regular 2×4 stud wall with R15 in it. My air conditioners face the inside of the garage. That keeps the garage warm in Winter and it keeps the air conditioners running. I do not have to worry about the girl room ever getting cold. No matter what temperature even at 30 below those air conditioners are running.
For water I laid conduit between the house and the garage and put two 1/4-in tubes for water and I also ran a heat cable in it, the heat cable is on a thermostat which is also in the conduit. If that does fail and it will eventually, I can easily pull that all out of the conduit and put new stuff in within hours. I also reclaim, filter, and sterilize all of my condensed water from the air conditioners and the dehumidifiers so I usually have a good store of water out there anyway.

When temps dip below freezing and you have a drain to waste system, or drain your dehumidifier(s) ect outside of your space, freezing over is a major concern.
The clear drain hose included with most dehueys with a pump option will freeze solid and cause serious issues…trussssssstttt meeeeeeeee. Lol
You can just put the drain hose in a 5 gallon bucket, but the better option is heating your drain pipe with something like this or similar.

Hey fellas ! Soak your media in the warm blood of your enemies. I don’t like space heaters because of the crazy power draw but sometimes you gotta do it. Try to use a dedicated outlet if you can. Foam board is good so is plain styrofoam if that’s what you got. Seedling mats can help keep your root zone 10 degrees warmer if you rock a water proof one.

Heard someone put a bucket of water with a fish tank warmer to heat the water in the tent. Claimed it raise the temp 10°

I love these for tents, mine has high and low button. I think low is around 120watts and high is 250
