What I am noticing about LED lights....

With HPS lights, you raise the lights as the plants grow.... Right? Always keeping the lights within 18-24 inches (depending on bulb wattage)

With LED, it seems that you let the plants grow up into the light. The light stays mostly stationary.
Ahh I didnt know this at all!!
I’ve been using 50% for my cuts then when they’re in veg I put up to 100% and keep it about 18-20” away, until flower where eventually by the end I can’t lift the LED any higher due to grow space.
I’ve been LST in the past so they tend to stay pretty much as low as I can keep them from start to finish. So never really get too close to the LED.

Any suggestions what is a good distance to keep the LED if it is to remain stationary?

This is a learning curve for me as previous years I’ve always been hydro and using HPS.

So I’m basically only a couple of grows in using Soil and LED. (noob)

Thanks again all!

Yeh I'm in the same boat. But here's a graphic that I found.

My advice would be to look up the manufacturer recommendations, like my SF4000 lights have this graphic that shows how far they should be from the tops. I am not sure if this is for all LED lights, or only certain wattages or......

This is great info mate. I vaguely remember seeing this in the manual I got with the light. I’ll dig it out and have a look.

Going by that guide, my light intensity has been too high for the seedlings and cuts, and wayyy too close. I’ll have to go and sort them adjust this asap. At least I’ll know for next time 👍🏻👍🏻👍🏻

Yeah that’s not quite how it works - most of go by a lux, par, those are the two most Common and inexpensive to ck imo I personally move my light and dial the intensity to what I what - example I like my board about 18” in flower and I run 45-60000 lux moving up the scale as plant matures then back in off before chop.

with led the closer to the plant with proper lux you will get the optimum penetration - sorry not a great splainer . Lol but that’s the most of it

I have one of those cheap ass PH/Moisture/Light meters, you know the green meter with the two metal prongs coming from the bottom?

When I do soil grows once every 5 years or so.. lol, I tend to start off watering like a newbie, so I get these meters to help me with moisture mostly until I get used to watering.

Do you know if these things are accurate light meters?

My 5x8 garden, is 7 feet tall, the lights are about 4 feet now. When I put the meter against the far walls and on the floor, it's hitting in the middle at 1000...... Not sure what the 1000 stands for. LOL!
