tell me if you know

I have my ladies in 3" net pots . About how big should I expect them to get ? It's week 6 and they are only 7 in tall

you should post a pic. There are many variables that go into the plants hight such as genetics and lighting, It sounds like you might need better lighting and possibly a bigger pot.

Details and pics please.

3 inch pots for a 7 week old plant. you should have transplanted after about 10 days. they are most likely root bound.

Since you said you were using net pots, I assume you are hydro? size of the plant will depend on light and nutes not the size of the pot like it does in soil .... 3" net pots are great in bubblers and dwc

happy growin

Yes its hydro and I'm using 400 watt mh in a 2x3 section

well if they are only 7 in tall in 6 weeks they are seriously not well and the lights aren't the issue...and any size net pot will work nearly...I mean not the tiny tiny ones...but close...I would rethink hoe much you are feeding the plants...they should be much larger by that time..

by that i mean you have overfed and stunted them...

I'm using canna aqua vega a b .....I stay within the directions

I've found that not enough light, over/under watering and over/under nutes cause stunting along with temps being too cold. If your feeding according to directions, Ph is ok, and your not over/under watering then lighting is the last reconizable problem.. their could be others but these are the main ones.

sorry couldnt be more help

happy growin
