I'm having a hard time controlling the tent's temperature because it's my first time using sodium lights. The plant is growing a little slow I think for this reason. As soon as I manage to stabilize the temperature of the cabinet in the next few days I hope to notice a change in the speed of growth of this small.

I have raised the lights 10 cm, to 70 cm from the plants. The temperature low to 30ºC but its not enough. Should i raise the light more? Should i buy a cooltube? What do u reccomend to lower the temp of the room?

This is by far the ugliest seedling i've ever seen. Mybe it's the hot temp, but his mates in the tent are not so ugly...Let's see how it develops...😄
About the temp. i recommend you to use what I used on my shrooms : Peltier.
You may buy a cheap water pump of 1/8 and plug to a Aluminum block and make the water circulate within the buckets. At the aluminum you put the Peltier (with a good thermal paste that's essential) and fix very tight, and at the hot side of peltier a good and large PC heatsink with a good cooler.
The Peltier makes the block cold, the water pass within and goes to the bucket making it cold. The peltier has two side, the chill and the hot, at the hot you must dissipate the heat otherwise it wont chill. SO... Chill it outside from your tent.
You must note that the pump shouldn't be much higher than the bucket. A 1/8 cheap pump could only lift the water around 1.5m, and that makes it loses the power of circulate water.
So:
Peltier (around 9 amperes would be enough for each tank)
Heatsink with cooler
Water pump 1/8
Aluminum block
12v power supply
And if it get too cold get an "W1209" and put the thermostat inside the water so it will turn off the peltier (if you install that way) when reach the temperature that you desire.
Colder water is best for the roots.
Good luck, any help just ask.
