8 days from seed  

They doing ok man, i would like to see them a little bigger after 8 days, but they green and standing so you look good at the moment

How close / powerful is your light ?

you could try moving it a touch closer and see if more light speeds up their metabolisms 

Check often to make sure it’s not causing stress (leaf  curl upwards)

slow growth can be caused by overwatering so be careful not to water too much at any one time 

hope this may help but as Macky said they are green and growing so no panic needed 👍

good luck growmie 

I'm interested you've planted with such a small amount of soil - is that to create more of a dome around the seedling? I would usually fill the cup and then use a sandwich bag strapped to the top to create a dome which may give the roots a little more room. i'm no expert though, just a thought!

Me too boombap. That tap root likes to dig deeply in my grows. On the next run I would definitely recommend more soil/coco un those cups.

Having a bit more medium lets you keep a correct moisture level with less attention - with hardly any medium you'll need to check them all the time.

i've heard it said that the tap root dictates size with autos and for that reason you should transplant into final pot fairly early or at the start.... with photos it's less critical. TBH not sure if that is actually correct - there are many variables. Veg time is so critical with autos - i get the odd beast and more than the odd runt

I do this with all of mine, autos & photos...start in a 500ml pot, as soon as they have 2 sets of leaves...straight into 18lt (Canna Terra) or 25lt (Sohum)

I'm trying to keep all my photos in the smallest pots poss until i sex them and then i'll do the same with the females. i'm really looking forward to that point.

I also do one transplant on autos - i wonder if it helps pause the onset of flower a little bit? (which i usually want to do)  - i neglected my grow massively before christmas and it was very cold in there - 2 of the 3 autos i grew on the side were so small and runty - 1/4oz on a stick type thing lol temperature is SO important in a grow.
