Can I use extension cords for pumps, fans, etc..

[Mr.]

The grow space in the garage is 16 x 23. I am building a wall that runs the down the length of the garage that will seperate the ballasts, water chiller, load center, etc.. There aren't any outlets in the grow space. So I will have to plug all of the fans (14 of them), water pumps, and UV lights into extension cords to run into the other room to plug into power strips that are plugged into the load center.

So first question: Is it safe to have the fans, pumps, and UV lights on running permanently on an extension cord?
Once the wall is built and I cut a hole in it to run the extension cords through, how do I seal it up properly? Is it ok if there are several extension cords bound together that go through the wall.

This is a sealed room.

what watt lights u talkn about?

 

[Mr.]

The UV lights are the low wattage reptile lights.

 

[Mr.]

I thin they are 25w

Check the amperage that the cords and power strips are rated for and calculate the load they will be bearing.
I'm in the same boat. I've got cords rated for 15 amps running from GFIs. I'm running around 11.5 amps through them(max at light start-up) and have not had any problems.
To seal the hole for the cords I would suggest some of that spray insulating foam. It expands and should fill any cracks.
