8 days in - indoor grow in cold climate

[dwizzlex]

Hi

Got my Mephisto seeds germinated and placed in airpots in small tent with a Viperspectra 450 LED. The seedlings seem to be coming along nicely but I am concerned with temps.

With the light on, a window cracked open and and my extraction fan running, the highest temp is about 74 degrees. I switch them both off for 3 hours per day and it drops to about 68 degrees. I haven't used my oscillating fan yet, but when I do in the next few day, the temp is going to drop to about 70 degrees max, even with the light lowered a couple of inches.

Will this do? I don't really want to start adding extra lights.
Any thoughts?

you're going to need a heat source. 77ish-85ish with lights on and a slight temp swing when lights off. You are going too stress and stunt your girls with those low temp. look into tube heaters like this, or small space heater in room with small intake fan . and get a fan going, the fan can help stimulate growth.

i agree with the tube heater i use one they don't take up valuable space and to be honest in the winter i don't have my windows open makes it to cold just try get then temps up also at a push some say they don't need a dark period and i think for early life that's correct also and its nice to meet you my friend

InkBird temperature and humidity controllers run my environment in set parameters. Heaters are reliably unreliable so a controller is a great buy. I use a tower heater, 22" tall in a 4x4 space, connected to my controller that only runs when temps are outside normal range.

Get a utility heater and a controller, the one I mentioned is amazing after a year, then set it for around a maintained 80f with the heater set to run when it gets to be 75f and possibly an exhaust fan connected (they are dual plug) that cools your room when 87f degrees is reached.

If you really want to optimize your room more, get the humidity controller, InkBird sells the humidity+temp controller for $70 on Amazon, with a modest humidifier and dehumidifier. With that you can optimize your room to be closer to VPD standards.

You don't need extra light, just better environmental control. I had to deal with the frost that hit last week and waking up to 60f grow tent because my heater tripped a breaker so I had to redo my electrical.

Thanks for the advice guys.
One other question. If I was to get a small fan heater for the room which the tent is situated in, and make the room really toasty, will this increase the temps in the actual tent.?

Food for thought: My radiator heater (preferred) sits inside a 2 drawer file cabinet (open face) pushed up to one of my tents low screens. The inline fan sucks the heat in very nicely without waste. I now have a second cabinet for my humidifier.
