Yes thank you mate they look fine for now so propably I won’t change a thingLess is more in veg IMO, so many people blast there plants with light. Save the power for middle of flower.
I'm never over 40% and closer then 30" in veg, you're closer and at less wattage so probably close to the same.
If they're not stretching then you're good, you can turn it up 1 just to see if they can take it.
You can manipulate the height of your light and intensity to lower or raise temps as well. In the winter it's easier for me to keep the tents around 80 with my lights higher and intensity higher.
I do have heaters and such but I figure if I can go without running them, lower the power load a little.
I don't start increasing intensity until after the stretch, I'll start moving up 10%-20% each week (if plants allow it) until middle of flower. I run the lights the hardest in the middle of flower and start lowering light intensity toward harvest.
Could you tell by looking on them? I can send you a photo after I finish work.. But what do you mean by praying ?I run seedlings for a month under a 2-foot T5, six inches above the tops. Then they move to my veg tent, where they're under 25% of my finishing wattage for three weeks. Then I bump them to 50% of my finishing wattage through week two of flower. On F3D1, I bump the light to 75% of finishing power. On F6D1, 100% of finishing power. I stretch the intervals out for longer-flowering varieties. I hang LEDs at the top of my tents.
That's my basic program, but the plants are boss. If the fan leaves are vibrant green, flat, and level, they're happy with the light. If they curl, taco, canoe, twist or otherwise contort, or if they're a color other than green, I turn the light down. If they're praying an hour before lights out, I consider turning the light up.
That's just the way I do lighting. Lots of ways to grow.
Look at those number ranges, they're double!!! So going by that chart double or half the amount of light is correct in all growing phases?Geez, have you guys never heard about par values
A number on a knob isn't very accurate...
Growth Phase PAR Level (PPFD) Seedling / Clone 100 – 300 Vegetative 250 – 600 Bloom / Flowering 500 – 1050

But he doesn't KNOW what his par is...Look at those number ranges, they're double!!! So going by that chart double or half the amount of light is correct in all growing phases?
What we are talking about here are smaller adjustments within those ranges going by what the plant is telling us. The op seems to already understand they need to raise ppfd as they go.
It is just another tool to help you dial in optimal conditions IF you do not already know how to...I'm not getting into praying leaves, there's a huge debate about it and no one really knows.
My tests shows praying has to do with how much the plant transpires, only 3 strains I've tested so far though.
As far as Par and Ppfd, growers have been reading the plants far before devices were even thought of that could read light levels.
Bud was way better then as well lol.
I will say that ppfd meters are good for reference points, not all genetics can take the same amount of light. We can't forget to factor in environment, nutrients, etc because that will effect how much light or ppfd a plant can take.
Bottom line is you need to know how to read the plant and if you can read the plant properly, you don't need any devices monitoring lighting or even nutrients. If you're always using devices and meters, you will never learn to read the plant.
If you don't think reading the plant is important, then blast your plants with 1000 ppfd in flower and all should be good...
Just so you know I'm stealing "measurebation"It is just another tool to help you dial in optimal conditions IF you do not already know how to...
No Tool is going to replace Experience but a helping hand can be a good thing !
I recently switched from a 600w HID to a 640w LED and did my due diligence.
Common recommendations were for +35w/sq. ft. and 600 par on the outside edges. Using that criteria I went shopping and was able to purchase a Phlizon FD6000 640w which is actually an upgrade and didn't break the bank !
Even after growing for decades I was able to fine tune my environment with this new information but ultimately the measurebation got old
Ultimately it comes down to do the best you can with what you have !
IMO praying leaves is a Good Thing, my Maui Wowie was praying and growing 3" per day !
