70 W system challenge LED vs. HPS #2

[Medved]

helou, the video was made yesterday, the girls were in 8 days of flowering,

here is the video

LED vs. HPS movie

enjoy the day

 

[Guest]

nice thread! i was wondering how things will go with the LED light!
it looks like plants enjoy it!
thnx for sharing!

 

[SirSmokalot]

crazy stuff Medved. good luck and thanks for the experiment.

 

[Guest]

LED still doesnt look as full and lush as HPS but they do look better this run, congrats and keep up the good work medved

 

[Medved]

thanx for stoping by everybody. Here is a little update. Girls are now in 11 days of flowering, and small buds are already formating.

First you can see both places together



Here is LED place



under the net in LED place



and over the net in LED place



Here is one small LED bud from AK-47



Here you can see HPS place



and HPS place over the net



one small HPS bud



I'm watering them only with filtered pure water, NO nutes. But I have some problems, that I don't know what exactly are they. There are a few leaves that are turning brown dots, and then turning yelow.

Here is a pic for better imagination




I cheched PH value of the media (soil) and here are the results (one is missing)



If anybody knows what's the problem please don't hesitate to tell me

Have a nice day fellow growers

5.8 ph in soil sounds a bit low to me...looks like most of ur soil is in the low sixes...i would get it to atleast 6.5...but who knows ?

 

[trapik]

yep, I second that.
6.8 seems to be what works best in soil.
It obviously looks like a low pH trouble on the leaves (from what I can see on faq and books, I've never experienced it).

thanks again for the 2nd comparison experiment (looks quite better btw!)

 

[Guest]

they said it, ph issues, is it only in the LED room?

 

[Medved]

rkone it's in both room. And I think that PH was the problem also, because I was measuring PH with another PH meter before (14 days ago) and it was not calibrated good :S for about 0,6 PH wrong. So I was actually watering girls with a PH about 5,5 - 6,2. Before 10 days the PH in the soil was about 5.00 I think. So now is much better, hope that there will not be any problems again Will try to rise it to 6,8 and will see, what will happen

Thanks on informations and have a nice day

 

[Guest]

good to hear you got it covered, your side by side is one of the more interesting grows happening right now

 

[budvapor]

if you haven't given them any nutes they're probably hungry...

 

[st0fr]

lol Simba you got totally ingnored...
Simba brought up alot of good points....but i guess its way to late for any of that....

lol my thoughts exactly.

Interresting though, how far down does those led penetrate?

 

[simba]

Ive realized i all i can do is give my Points/Ideas/Results from my last 3 years of Pure 24/7 growing. (not for fun or Product to sell or consume rather finding what works why etc and finding what doesnt and why it dont.)
oh i grow for work LOL well experiment with everything for work.. Man i love my job (and many years prior, that where for fun or working for fam Garden cntr)

and i try not to dont PUSH my Results.. (except CMH, LOL Only because that one IS NEEDED)
i know im just ahead of my time.. LOL

Nice grow though Gives him great experience.. (the one big thing i give LEDS u understand that mylar is garbage fast, and how Light Behaves (reflection, refraction,difusion. etc, because LEDS have a colimated beam (depending on optic or reflector)

 

[LordOvertoke]

bookmarked.....lookin' forward to the rest of the show.

 

[jws0007]

This sounds wonderful.

 

[Medved]

Finally I have found some minutes for short update. I work too much.

The girls are in 21 days of flowering and I watered them with nutrients 4 days ago. Because I think there was missing some N in the HPS room.

Here are the pics







and a HPS bud





here is a LED bud




In next few days there will be more updates, I promise that.

Have a nice day

 

[Medved]

helou everybody, it's time to show you something nicer than before Girls are in 24 days of flowering and looking sweet

here are some pics
















and HPS







Have a nice day, till next update

 

[Guest]

they look more even this time around, although i feel like the hps is still just a tad farther in development, but then again maybe im just biased

 

[blackone]

Yeah a couple of the hps buds are looking more fat but it does look pretty even. This is gonna be fun to watch in the coming weeks.

 

[reaperz]

keep up the great work cant wait to see the finished product and the comparison
