heater in grow room/closet

its starting to get chilly, night time drops to about 30 degrees in the shop, is it ok to use a heater at night to keep the temps up. got 5 cfls on 3 lil guys almost 2weeks.

its a fan with heater built in. set on low
prolly let it run just at night, a 150w infared light comes on during the day cycle.

any help is appiciated.

I would also like to know of a good heater to use in a grow tent

Heaters can be used. They make units that have built in thermostats. This way you can control the temps better. The down side of using a heater is that it will affect the humidity of the room.

try heat mats that go under the plants. If you haven't got a big grow room this can work well you can also control the temps on the heat mats. They are about £30 so if your in the US maybe about $60.

I got a heat mat for my propogator at the local hydro shop for $28.00. It keeps the mat temp 10F above the ambient room temp. It works well for cloning but I am not sure if that is going to help your situation.

is this what your talking about?
