What is considered "day 1"?

[panalilies]

Is it when I can see green or when its all perky? Pic below, unsure if I should consider day 1 today since it broke soil, or wait until its fully sprouted/ open?

That's day 1 to me, it has begun some type of photosynthesis as long as it is getting enough light. Some don't start until the first true leaves emerge. You may very well see tiny pointed leaves before the day is out! But if not don't worry, they are all different.

Now if I can just remember when day 1 was.

Yes are you in coco or soil? I use a spray bottle with proper pH water and just wet the soil or coco. Usually about 4 or 5 sprays with my spray bottle. That way if you feel the need to water you have little chance of overwatering. The roots are still near the surface the first week or so.

Coco, I have like a 6-6.5 pH, I have a digital reader coming today so I can get a more accurate reading than a color test. I do about 3-4 sprays every time I water it. When you say just wet the coco, do you mean spray around the leaves and not on them?

[Catfish22]

No don't spray the leaves, just a 3"-4" circle around the stem.

Day 1 begins as soon as your plant is poking through the top of your soil.

Thank you! I have officially marked today as Day 1 on the calendar

I count day one when the seedling is fully out of the soil.

PLreef A few days later than you my friend. Maybe the reason why I'm always fu..-up with my flowering period non ?

[PLreef]

Who are you kidding?!?! You have always had amazing flowers! I grow autos so veg is quick. I keep track of veg and flower but really only pay attention to the days during flower.. In the grand scheme of things a day or two don't mean much right?

At the end it's really the trichomes who have their last word for all of us right ? Regardless if you are an auto or photo grower.
