Newbie auto grower has made a total arse of his first attempt...

[Coffeesynth]

The grow box has a heater, yes. And it's insulated. The exhaust fan runs at minimum in the dark, and the heater is set to come on below 16°. In the light the fan runs at a faster rate and the heat from the lamp keeps the temp at abput 17 to 18°

Outdoor temp is about 8 to 10°

I've now increased temp to 18 to 19° in the dark, and about 20 to 21° in the light. No more watering!

Sounds good! Lets see how they reply after a few days

Its still a little on the cold side but Ive grown in colder, just make sure that the temperature doesn't swing too much between day to night. I know you said you got a bit of experience with photos but neither likes huge temp swings. Im not to good with conversions but 10°F is about what you want the difference between day and night temps. More than that can cause shock/stress/stunting, and depending on how stable the genetics are herming. Most auto lines are pretty stable now though.

My temp difference is only about 2°C (3.6°F) due to using a TS1000 lamp which gives out very little heat and cranking the extractor up a bit when the lamp's on. The heater is on a thermostat 24/7

Rather than manually "cranking the extractor," consider putting it on a thermostat too, like your heater. Then you can have 24/7 assured temperature control (such as set heater at 78˚F, set exhaust fan at 80-81˚F).

Also, besides fans directed towards the plants/canopy, consider having one circulating air within the tent, such as sitting on floor pointing straight up or mounted up top and blowing across the tent top, so you don't end up with most of the heat rising, cooler air setting (also cools the lights).

Thanks for all the info

Along with what BII said, inkbird makes thermo/humidity controlled outlet controllers, much like grow hubs for tents that do all the controlling the inkbirds work the same way. Its like an outlet timer controlled by temp and humidity setpoints, though they can be a little pricey.
