Temps. for seedlings

What would be good temps. for seedlings about week old and very nice looking. How low of a temp. would cause alarm…slow or diminish plants growth. I know that older plants can handle temps in the 60’s but how about ones that are just getting going? I am wondering what others have done. thanks and this hit is for you

70 is the lowest I am comfortable with.

I feel that would be better but how long do you leave the lights on at this stage?

I have my canopy around 80 to 85. With the cold front it’s probably in the mid 70’s to 80. I’m not home so I can’t say what it’s like right now.

I put my seeds straight into their final home and into the tent. So my temps growing from seeds to plant I mentioned above.

I run lights 24/0 until rooted then do whatever: 16/8 usually.

Thanks, so now as I see it, your temps stay in this range from start to finish

Yup…only time it gets crazy is during our Summer months from March to Nov/Dec.

I checked on my girls early this morning and the canopy was at 75 degrees. Only because the temps out side is well before 45 degrees. This is the prime time to grow in South Texas.
