I have a Black Widow, and a Northern Lights plant that I started from seed. They are both 3 weeks old today. Both plants have good colour, but dont seem to be growing height wise very fast. They are now about 1.5" tall. They both have about 6 leaves on them. I transplanted them once and are now in potting soil in 5" pots. They get light from 300 watt full spetrum LED light, and they are in a grow tent. I think it is actually putting out 150 watts. Tempature ranges from 70-75 degrees with 60% humidity. I water them twice a week. Light is on for 16hours, and off for 8. Light is about 21" from plants. I did have a small fan on in the tent, but decided to turn it off to increase the temp. So, my question is are they at about proper height for thier age, or am I doing something wrong? Thanks in advance for comments, and suggestions.

They will kick in once the roots have established and the foliage gets large enough to absorb more light

Yeah I think it's just a strain thing man. Cause I got 4 seedling that r 12 days old and already standing 6to8 inches in height and a couple of 5dayers in at about 3 inches they should start to take off have u given them any nutes yet? Or r u going soma style with just water . I'm not gonna feed until bout 18 days in myself. And r u giving them reversed water? The reason I asked cause regular sink water could stunt growth sometimes because of the chlorine and stuff as well as early feeding or late feeding

Also I would like to know your light cycle. I usually start off with a 14/10 myself since cannabis does most of its thing during the dark cycle. Good luck never had black widow but I have had the white. Couple of the guys and I could barely put away a blunt of that stuff kickass genetics u got going man hopefully they turn out the way u want happy growing. 4204ever

Also they could be staying short because for seedlings you have a lot of light on them so they won't stretch very much at all, and 1.5" with 6 leaves sounds like short internodal spacing to me. Without pics it's hard to tell for sure, but I think you're fine.
That's pretty well what I was thinking Ace. At first I read it as 1.5' which would be a tremendous grow
We'll have to check the grow out after he posts pics tomorrow.
