Growing Gunnera from seed?

Hi Everyone,

So I've decided to try and grow a Gunnera plant from seed. I currently have around 4 germinating seeds in a small pot at the moment. There's a root but there isn't any leaves as yet as the seed shell is still covering the shoot. It's growing super slowly so I'm not sure if our dull weather will be ok for it to continue growing or if I'm best to put them under a grow light for a while?

 

I think you are going to need grow lights for the next few months.
The days are still getting shorter.

 

Thanks, My biggest challenge will be not incinerating them with the lights as usual!
