These are looking good MagicJim. Wow! How did you manage to get such consistency in your environment? I don't think I've ever seen readings like that LOL! Just a heads up, a happy plant likes a 5-15 degree temperature drop overnight, or lights out for those running lights at night to save energy costs or beat the heat.
How cool! Mystery bag seeds.
B A R (and many others) likes to use his for experimentation and everyone uses them for starting I think. Those ones going back into the 70s - I'd keep them separate, if you haven't already thrown them in together. Regardless, it gives you the thrill of the unknown, which can sometimes be the best. I have one running in my own tent right now that I saved from a bag of incredible stuff I bought for New Years. I hope it turns out to be female. Its the last unsexed plant in there. Somewhere there ps a video floating on sexing seeds. TOAST uses the method and has been surprised to have an almost 100% success rate in separating out female seeds, so you might want to talk to him about your seeds. I believe I have that video in my blog list if you wanted to go looking.
Never mind. I dug it out for you.
Isn't the loupe fun and challenging? There's this tendency to have a slight tremor that comes with age and frustrates many of us seeking that fabulous close-up. Keep it up, you show promise, if only in the level of joyful curiosity. Are you just exploring new territory or looking for signs of sex? They won't show signs of sex until they're under 12/12 or less. If you want to accelerate their finish, you could consider going to 10/14 lighting. Dr. Ziggy is running his Z'ACE tent at 10/14, and look at what he's got going on in there right now! Envy!!!
This time next year, you're going to shake your head in wonder at how far you progress down the path to Master Cannabis Cultivator. Magic time soon Jim. You chose that user name well.
