Hey guys! A quick update;
3 of the 4 have popped now and are just unrolling their cotyledons, looking good I'll take some photos when theyve finished making themselves look pretty

Still no sign of the 4th, she will have been in exactly 5 days this afternoon. Not giving up hope for her, im going to be a little gutted if shes a no-show thoughas I only had 4 seeds. Fingers are well and trully crossed though!
Had a little breakthrough with the temperatures when I realised my ballast was right next to one of my air intakes, so ive moved it away which has brought temps down to just over 28, which all sounds pretty good to me!
Happy Horticulturalist, I dont have either of those things as of yet but they wont be a problem to get hold of if you think they will be handy to have. Im splitting everything with my sister so ive got a bit more wriggle room when it comes to budget.

I do have a ph/moisture 2 in one probe but it wasnt exactly top of the range so I suspect its going to be useless for anything except give me a vague idea, so I'll have a look for some this afternoon. Any that stand out/that you would reccomend?
And JAYAR, I posted a pic of my setup in the first post of this thread, but let me know if it doesn't work and ill upload another.
Cheers everyone! Peace
