Are my seedlings too slow? (10 Days old)

Barraka · Thursday at 3:36 PM

Seeds: Super Lemon Haze x Pink Candy (Greenhouse Seeds).
Quantity: 3.
Type: Feminized photoperiod.

I germinated the three seeds in a wet paper towel on the 10th (15 days ago). 2 days later, they had germinated and I put them in peat pellets. On the 15th (10 days ago), they had emerged so I started the 18/6 light cycle under a 175W (from the wall) LED, around 45cm above, at 30% power.

I water them every 3 days roughly, with pH adjusted water. They are in 2L pots and I used potting soil for seedlings.

So here's what they look like after 10 days, they seem reaaaally small to me, compared to what I see around here. One of the 3 is visibly a bit larger than the other 2, but still too small imo.

What do you guys think?

No there about right size. They will take off soon. Tell us your plans with them and the setup your gonna use. We have loads of information from this forum that can help you. Best of luck and welcome to the Farm

The size looks ok but the color looks like they need to be fed.

About right.
Lower temps have a big impact on the speed of my seeds and seedlings - not sure where your at.
Also my older seeds are slower to sprout and grow initially.
You may be able to go stronger with the light if you wanted, I usually start at 75% @ 30" or so, depending on how they act.
But, even if they are a little slow for any of those reasons (or another) they'll probably take off eventually and you'll only have lost a few days in the process.

Thanks for your comment. My temps are around 82°F, no idea about my humidity though. Yeah I'll maybe pump up the light, maybe to 40% and see how they react.

stop using the ph if your using potting soil,.

For what it's worth, I had prepared a container of ph'd water of around 6.5, I used it for a few days sitting in my garage, and today I measured it, it's around 8.4

I'm not using it obviously, but I didn't think that a container that I had lowered from initially 7.5 pH, down to roughly 6.5 pH, would eventually increase to nearly 8.5 WTF?
