Correct. I believe it’s on the 3000 and 5000 but not the 7000 which is weirdThat is likely the UV. That means extra trichs.

As a new grower can I ask you what stage would you consider your rooted clones? Like how many weeks in veg? I'm trying to better understand environmental needs and vpd.. Since they are rooted and the roots are expanding, there is no longer a need for that 70-75% humidity?Their taking to their new home quite nicely. Already root locked on to the slabs. I might even say, it looks like they continued growing through the transplant. They look bigger than they did yesterday to my eye.. I can't say enough good things about this block on slab technique, so many benefits including zero transplant shock right from rooter to block, block to slab.
Saturday I'll top them so they should develop 8-10 branches or so each, which I will double again in about 10-14 days by topping the branches. Aiming for 16 main tops per plant. That will give me roughly 250 or so tops. At 4 sqft per plant, each top will have its own 6x6" growing area. In theory.
A few days before I flip I'll strip each branch to the top node, and 3 weeks after flip I'll do an aggressive defoliation, not complete, but aggressive.
Current room conditions, 77-82f, 55-60RH, light 5mph breeze from the southwest. Perfect day for stretching out those leaves and branches.

I'll try and make it as simple as possible, I break the grow down into 6 loosely defined sections.As a new grower can I ask you what stage would you consider your rooted clones?

Very very much helps!!I'll try and make it as simple as possible, I break the grow down into loosely defined sections.
1: Rooting phase. When clones are in the dome waiting for roots to pop. I aim for 85%+ humidity and a temp of 75-80f. Last about 2 weeks.
2: Nursery phase. Also called the preveg stage, this is after rooted cuts are transplanted to their first home, either a 3" block in my case, or a red solo cup, or small Nursery pot etc. I aim for 65-70% humidity and temp of 75-80f. This stage lasts until the starting container is well rooted, usually about 10-14 days.
3: Vegetative phase: when the plants are removed from the Nursery and transplanted to larger containers or placed on grow slabs. This is when I lower humidity to 55-60% and increase temp slightly to drive transpiration a bit harder. This stage for me lasts 2-3 weeks.
4: Transition phase. The first 3 weeks of 12/12, I'll keep RH in the low 50's and temps high 70's.
5: Mid flower. Rh high 40% temp high 70's
6: Late flower: RH as low as possible temps reduced to mid-low 70's and light dialed down to 40%
Hope that helps.
My pleasure. I should also say that you can really grow pot in almost any humidity within reason, lots of folks grow in low humidity environments successfully. But I am a believer that growers can use VPD to fine tune the environmental conditions, and that it can be beneficial and lead to healthier, faster growing plants.Very very much helps!!
Thanks
Yes! And thank you for expanding further when I think you knew where I was going with it. Nice Folks HereMy pleasure.

I believe It's been shown through a fair bit of testing that plants retain more terpenes and cannabinoids under reduced light conditions during the final ripening phase in the last couple weeks of growth. I dont have any links off hand to actual studies, but I've heard this from enough people I trust that I believe it. But now I need to actually research it lol thanksHey Dirt that was a great write up about your 6 stages and super helpful. May I ask why you lower the lights intensity at the end of flower? I understand this mimics nature but I am sure you have your reasons so I am curious.
Thank you for this. Truly. Now I have some specifics to try and address for a better grow.Also should point out, I don't just cut light back to 40% overnight, I'll start a couple weeks from harvest by dialing the balasts down to 750, then 600 a couple days later, then raising the lamps a little each day and eventually have them up at the cieling for just the last 7 days. That was with my 1K HID though, the LED's I'll just dial down over the course of a week and then leave it low for the last week.
