Grow Room Problem

So basicaly the problem I have is this:
(I had to move my grow room)
Ill start with the basic run down of my grow room:
-400wat hps
-Growing Kush
-Humidifier
-Mother earth, super thrive, and PH is fine.
Here a few pictures

This is the main entrance to the grow room



Don't mind the mess/shitty flooring


My baby right now, beside it is a heater(which I will explain) and a humidifer

So MY PROBLEM! which is while a big one
So I came home today from work and my Temp in side the room was mid 40oc WHICH is not good. Then I turn the heat down on this stupid heater and it droped to 21.4oc, I can deal with that. Now when I turn my light off the temp drops alot like down to 10oc

Problem heat marjo fluctuation

So far I also have no vent or fans inside as well the top of my grow room has nothing on top of it so while some air flow come from that

Grow room size is 3 feet by 3 feet and 6 feet high

Please give me some advice not sure what to do.... Right now im running a small heater plus a base board heater WHICH is to MUCH already seen a increase in my hydro bill

Please help
Thanks

You need one or several of these http://www.gil-lec.co.uk/products/Heating/Tube+Heaters...I use one in a cold grow room and the difference between on and off at night is literally night and day! Just put it on a timer and it should help alot, gentle heat off it.

EDIT: Nevermind, didnt see that your running heaters already.

Im thinking of basicaly some kinda cheap insulation might help untill then i guess im going to run my light 24 hours instead of the normal 18 hours

I wanna also add I live in Canada and for the next two month I need a basic simple 10-15 deg boost!

Yea I understand that the light gives off heat the problem is when the light is off the temp drops! to like 10oc, which will kill my plants. Ive been able to keep some what of a stable temp right now between 23-27oc. Tomorrow I might buy some wheater stripping and cover my grow room in it. The problem is I already lots of money so hope my crop turns out good

hope that helps. That plant looks pretty stretchy to me and that is caused by colder evenings. A larger heater with a good thermostat would probably be the most effective solution. Home depot has suitable heaters for like $80.

the plant dosnt look heathly?

Not really dude. The nodes are spaced way far apart, there appears to be several stems missing, some of the tips are burnt and the leaves are all drooping. Probably just needs a much bigger pot

alright its a mother plant i bought off a buddy so maybe ur right

I was going to say, it looks like a mother that has been harvested. You need to top it, or better yet, tie the tops over to get it bushier so you can take more cuttings off of it. And put it in a 5 gallon pot asap.

Cheers.
