There's something very cool with the blend of colors in the background from the three generations of grow lights behind Shane that makes for a great visual and a truly classic video!

[Cannabissssh]

Shane, you are AWESOME! I find your videos unbelievably helpful as a new grower. Thanks for all your work!

[highdrogrower]

A lot of good information👍

I usually adjust the lights according to stretch or heat stress, if the plant is showing signs of stretch I'll lower the light and leave it for 24 hours.
If it's showing signs of heat stress I'll higher the light and leave it for 24 hours, and a good isolatating fan blowing between the lights and the top of the canopy lets me get the light that little bit closer.

Yeah man we are all here for "medicinal plants in flowering stage" 🍃🌺😂

Excellent. You've confirmed my current process. The foot tall seedlings are all doing well. I have my light at the top of my grow tent and I'll now come down a foot for a week and check again.

Little did we know 4 years later there would be a flooded market if LED, you should make a new video with this…..happy growing 🤙🏻

can't say it wasn;t thought life is more important than watching that all the way to the end. i hope it helped someone who suffered thru it

Adjust-a-Wings also make Super Spreaders to go with
with their high quality adjustable reflectors which
dissipate both light and heat more evenly preventing “hot spots”. Thus allowing for closer proximity to the canopy.

You speak soo calmly you make me believe every single word you say 🤔👏🏼👏🏼

[maclean]

He's so stoned, very good video you got to love the Irish people.

[lipptech]

Could you please do a video specifically targeting how high to set l.e.d. lights as we tend to have to mount led lights higher than hid lights as the led's tend to bleach out the top's of plants due to the light intensity I would suspect. Please elaborate on this topic.

Thanks Shane, this is fast becoming my favourite YouTube channel, De Bacco University on YouTube is very good too.

[dannygreen]

So glad I found your channel. I have just brought a Mars hydro tsw2000. And wasn't sure.im used to HPS.thank you.

[andrewjackson]

My plants are growing tight and short. No sign of nutrient deficiency, but after 8 wks they are only 12 inches tall….someone has told me to lift my lights and make them stretch….what do you think?

[baymaster]

thank you i had my light to close and my leaves burn thank you for this information cheers from the bay area california

[ForPropertyInvestors]

Maybe measuring out and tattching a dangling a streamer or bob-wait line on a string from the light so its a reference to the top of the plant or canopy.

[valueape]

YES! My plants fried under the too-close lights last time just as you described. Tried fiddling with LUX phone apps but keeping Leaf Surface Temps just under ambient room temp may save me this time. I have an IR surface temp gun / baby thermometer that I can use! Thank you!!!
