First official grow

Now is the time for lots of light. What's your lux at 21"? A little over 300,000. How much do you think I need. They have grown a couple inches over the past several days. They seem to be slower done.

30,000? IDK This my first led grow I'm about 30,000 @ 16 inches. Not sure I trust this light meter. Never used one before I just kinda know with the hps and mh. I keep hearing people say you need 85000. If I gave them 85 according to my meter they would be dead in no time.

That's crazy. I can absolutely max out at maybe 60k before they show light stress. This is measuring with a separate lux meter, not my phone.

60k would be about 9" directly under the 100w hlg according to my epsilon light meter. I may lower mine a bit but not that much. Maybe one inch a day. I was letting them grow to the light but the stretch is done now.

Probably. I would try out 40k and see how they like it.

Like I said, absolute highest. I would do as you are doing and just watch and feel. I am also only running 11 hours of light during flower this grow.

Tough to stay dialed in with these new LEDs. You're 12 inches now at 43k directly under the light and maybe 30 at the walls. The plants grow 2 inches they're at 60k. HID is easier to dial in and more forgiving. This shits a real learning curve for me.

It's because each move is a greater proportion of the whole distance. If you were to run the same true wattage, the led would be much further away and much more even.

They will still get a little taller- not inches a day though.

You are going to hear mixed remarks about that topic. IMO I would do another round of it. My reasoning is that that tent looks stuffed to the gills and you are going to have to watch closely for mold if you do not do another round.

I don't. In extreme cases of overcrowding, like yours I might remove a few select fans near the center of canopy. But nothing heavy.

Also any bud site below about 5 nodes I would remove for sure. They will just be larf if you leave them.
