It's tiny! I've got some plants that just sprouted three or four days ago and they're easily triple that size (fourth set of leaves is emerging as we speak).
What are these "full spectrum" lights you're using? ARe they floros? CFLS? CFLs are usually labeled with "equivalent watts", so your 70W bulbs are really only 15W if that's what you're using. May want to step up to 26W or 42W bulbs instead. Those "full" spectrum floros are 5000k, which are okay for growing, but you'd be better off with 6500k.
EDIT: please don't listen to the people who tell you to give that tiny seedling fertilizer. it DOES NOT NEED FERTILIZER until it's out of the seedling stage (3-4 weeks from now).
Is there anything I could be doing to help growth ? I hear when there is free air and a bit of a sway it thickens the stem and helps photosynthesis. Any other tips like that ?
I respectfully disagree, 3-4 weeks before any nutes for a seedling? 4-5 weeks and my seedlings are in Veg. My seedlings are 4" tall (and 4+ nodes) after 3-4 weeks and definitely need nutes by then.
First week or two, I can see the argument for that, but 3-4, I think that is definitely way too long. IMHO.
It maybe tiny, but every strain is different.

In my opinion, nutrients help but keep them mild. I'd wait a bit on circulating air, dont want to dry the little one out.

I agree, I'm so impatient. That's why I kept watering them so much, so it was something to do. But yeah the roots are massive.
Should I wait for the soil to dry before I water so the roots search for the water ?
And how often should I water ?
