LED grow

[Lrus007]

then gmo
most the plant.

then the top.

then lower down.

then the clones on back side are doing well.

the end of the beer cups lol
was a few posts because only so many photo's per post.

well bud growing on shade leaf stem is still going.

the plant chemz is almost done here is a bud shot.

here is a top lowers seem to look better.

then posable nanner or just a odd light green leaf on the wedding cake.

mid way down on the wedding cake.

then top of the GMO

i am debate with the LED's pros and cons. seem to have more
cons. was taking winter off i got plenty of smoke. but a HID
going helps keep pipes warm in the freezing weather. so i think
i will do a round under a MH. will stagger plants 2 weeks or so.
i will bring up my pro's and cons in another post.i am sure prawn
will have a long rebuttal lol

Haha! No, not at all! I actually produced two different types of LED panel when I first started doing this and one of them was designed specifically to work with CMH.

Here is the "High Red" LED panel I designed (note, no UV and lots of red and far red light)

Here is a CMH spectrum (note, lots of UV, blue and cyan light)

And here is the combined spectrum

And here is the result – the above measurements were of an actual grow, this one

I actually tell my customers that if they have a HPS or CMH and are concerned about low temperatures during winter, not to get rid of the HIDs and to run them with the LEDs when its cold.

The basic rule is, if your ambient temperatures are ideal (around 30C) then LED will prove itself every day of the week. But if you need to add metabolic warmth then there is nothing wrong with using a HID to supplement with infrared.

What I would suggest is that if you are going to mix LED with HID, then you try to balance the spectrum and not have too much blue. MH has a lot of blue and green, while CMH is more balanced. HPS has a lot of green and red (and especially far red, which is beneficial) and very little blue, so can compliment most LEDs. However, most LEDs have no UV and neither do most HPS lamps.

So if you can combine a CMH lamp with a high-red LED panel, you get the best of all worlds: warmth, UV, far red and a nicely balanced spectrum.

LED is a no-brainer for me because it doesn't get very cold where I live, but it does get very hot. I also grow indoors which means there is not a large variation in temperature year-round because we regulate our indoor temps during winter and summer. But if anything, I am trying to reduce heat in the grow area.

my opinion i could be wrong lol it happens

1st a little back story. years ago went to amsterdam.
noticed pot was not as good as in the PNW. also noticed
smaller buds. so asked some growers what they used.
most said a 400 watt and a few a 600 watt. no 1000’s
there power is watched and expensive so use smaller lights.
is why there buds were smaller. so to get bigger buds need the watt’s.

ok grown out a few crops now with LED’s got some pro’s and cons.
i have grown under tubes, MH, HPS and now LED’s never tried a CMH.
i have always done the best with MH. room is a cold wet basement.
can only do led bloom in summer when warm enough outside and inside.
the LED’s great coverage. do go 2 - 2 1/2’ deep into plants about same as
MH. the LED buds grow more spear shaped vs a lollypop under MH. i noticed
with the LED’s i have not had to tie up large buds. they do ok i got over a 1/4 lb
per plant under them in a 1 gal pot. the lowers seem to grow better under LED’s.
under a MH i have to tie some buds down and lowers are not bad. i do shorter
plants then most people do. less popcorn/larf with 2 1/2’ plant or so. i have a few
LED grows under belt now. so going to do a MH run same plants same pots
just to see the difference. plus keep house pipes a bit warm to boot. i will take
1 of the 300 watt LED and put in transplanted / teens room it should work nicely.
with the LED’s i had a learning curve and not quite there. if there to close they get
light bleached and look like collaflower on tops. to far away and buds grow long
spears. i do have some strip LED’s around a MH cage they help with the lowers also.
ok lastly with some more LED cons. had 3 different plants throw nanners that never
did before. then i had 2 plants get some mold for the 1st time in bud. then the kicker
lost a plant i have had 42 years the LED’s just cooked it. did same to another plant
i had over 20 years. so lost 2 strains to them. they did not like the change.

trimmed on sunday. i have not grown wc or gmo or smelled/smoked
them before. i trimmed one marked wedding cake. not bad of a trim
very gummy. after i trimmed person i got cuts from says he thinks that
he sent just gmo cuttings. were in different clone bags 1 marked wc
other marked gmo and 1 marked sensi star. he thinks he took wc off
wrong plant. after i trimmed had he told me a day before i could have
stared the 2 plants next to each other. so walked back and forth looking
at shade leafs between them ect. then smelled what i trimmed think it
is gmo. then smoked some scissor hash and made me think gmo more.
plant left is marked gmo is about done. smells a little different so maybe
he mis marked them.i will know when i trim down in 2 weeks. the chemz
gets trimmed this sunday. so here is the bud on a leaf stem looking good.

be trimmed next sun. i will cut the shade leaf and hang it to dry.
then here is a bud shot of the chemz.

and here is either gmo as marked or wedding cake mis marked.

when these are done i will switch to MH for bud and led for clones/teens.

he will resend wc if what i have is 2 gmo's

whats gmo. I assume it's not what I think.

At least I'm pretty sure that's what Lrus has.

you are right bob

moved LED to grow room. plants faded a lot since tubes. i have
been raising them with hope of greening up. is mostly
the old a11 not liking it.top right of photo. looks a little better
today. i put a cfl by it other day. it is like the led's are missing
a spectrum to make darker leafs. like under tubes or HID
the leafs are much darker. then maybe i just have them
to close. am a old dog learning new tricks the hard way.

plugging in a 1k on sunday and will bud the plants under it.
trying to do a plant every 2 weeks added. this will be number
one with all that light to it's self. then hard part of timing.

You need a good Cal-Mag supplement with nitrogen.

LEDs run cool so you need to increase your EC – and especially Ca, Mg and N – to offset reduced transpiration.

I see this all this time. Most of the time it is cleared up by a good NPK feed!

All my LED plants and seedlings are green as fuck, but I run much higher ECs – even from seed – than most people would dare try under HIDs or fluoros. It can also help to run your pH a little higher in veg to make calcium and magnesium more available.

You have a magnesium deficiency in your photos. Nitrogen helps uptake Mg, so that's why a good NPK fertiliser can also help.

Here's a grow from a mate who is a complete indoor noob on his first grow in coco under lights. I gave him a nutrient regime to follow and he is smashing it.
