Marijuana seedlings growing to slow...need second opinion's.

[Daniel and Jessica]

I'm pretty sure my plants are about 3 weeks old, and I don't know if it's just me or are they growing slow? Look at the pictures and our setup and let me know what you think!!!

 

[Daniel and Jessica]

And these are pictures I took before the new ones in my post.

They are tiny.
What kind of light is that?
Need strong light, and air flow.

Ya they are growing slow and stretchy due to the lack of the right kind of light.

Do yourself a favor and Google photosynthically active radiation or PAR.

 

[Daniel and Jessica]

Thanks for the quick reply...their this kind. .and I got heat coming in and that purple fan is pushing our the back and in the middle is a humidifier

Hey I'm trying my best lol

1 week after repotting the seedlings. ..thus is roughly 15 days of growth..from seed

Agreed..light ..color spectrum. ..par

Those aren't the right kind, that's why your plants aren't growing well.

is this a better light to use? Plus the 4 lamps? And when we're done building this final grow room move them?

Like I said, look up PAR.

What kind do I need?

Alrighty

 

[6ohMax]

I recommend a T5 or a lower wattage MH

You need light that has a significant amount of radiation in the 400-700nm range. Research time.

Also your humidity is low 41 is a pretty good number for flowering but 55-65 is what u want in veg

 

[Daniel and Jessica]

Here's a update temp 75, humidity 40%. I'm pretty sure the old pictures I was over watering and I'm not watering as often but idk.

I could be wrong but it seems plants also slow down if it gets cold. Just like how peppers go dormant in winter.
If you're in a cold area a heat mat can help the roots somewhat.

Alright thanks for the advice! Would you like a picture of the temperature and humidity?

 

[Stealthstyle]

ok, but heat above the plant can be different from the ground temp. Cold ground temp can slow down roots in my opinion.

Update, the one that looks like it either has nutrition burn or root bound I transplanted into a bit bigger container and I gave it these nutes (in picture) so hopefully we'll see some improvement. Any opinions or advice is helpful!
