I’ve learned that during veg you want it warm and humid. 75°-86° F/ 24°-30° C. And I tried to keep my humidity between 60% - 75° humidity.
However a slight temp drop is a good stresser during veg.
For flower I keep it between 65°-75° F / 21°-25/26° C during the day
60°-65°F / 19°- 24/25° C during night
You’ll want the area being covered by light to be within the 75-86° F. And as long as you can keep the temp from dropping below 70 at night you should be okay.
Good luck and hope they bloom beautifully!!!

The strain is Durban poison, and I planted it in the soil coast of Maine potting soil which contains lobster meal and lots of good nutrients it was 20.00$ a bag but well worth it so far :

A plant is mature enough to flower after about 4 weeks of veg time. But a photoperiod plant needs the light to be under 14 hours per day to trigger flowering, so depending where you are, some time in early August you should start seeing pistils.
Check on www.timeanddatecom and set your location. This is also good for when to put them out in the spring. I’ve put them out too early and had them start to flower early on me before! Oops! But that was the excuse I needed to convince the wife that I needed a tent to finish them off inside…didn’t know about revegging plants then. Which is a good thing, got my setup wife-approved!

Have only used big bloom so far plant is potted in ocean forest bottom 2/3 of pot with happy frog on top 1/3 i am week 5 on plant so i will be adding some tiger bloom soon what do you think
I bought the feminized seeds and it’s getting like 12 hours of sun so it should flower and bud in 7-9 weeks ? Right
I’m not using any nutrients, I wanna see how it does without them
I bought real good potting soil called coast of Maine that had a lot of nutrients and lobster meal so we’ll see lol
Canton Ohio, sunrise 6:12am, sunset 8:51 pm. That’s 14 hours and 39 minutes of daylight. On August 9th you get 14 hours and hit 12 hours on September 26th. Unless you cover it late afternoon…

I would expect to start seeing flower sites mid August or so and be ready to harvest mid-late October. Your soil is good but probably not going give you best possible results without anything else over the course of grow.

I’m here in Huber heights Ohio, thanks for the correction of sun light lol I just thought it was always 12 hours, that explains why it’s growing so fast
