Good job anyweight !

The two unknown landraces prooved to be two different plants (easy to distinguish from their phenotypes...)...
Maybe so ,one is / looks more " Indica " dominant and the other more " Sativa " dominant ....

So...

The "indica " dom plant ..Response under the "central flowering " panel -.
.....totally experimental : Type ala EVo 3.....plus .....

10 x reds 620-640 nm
10 x CW 6500-7500 K
2 x WW 2700-3000 K
2 x Violet -UVa 390-410 nm ...

Click to expand...

Flowers look like that -at " 2nd day of 7th flowering week " :


My hard guess is this...
Plant's PS rates reached 100% and more ..for prolonged period...
High PS rates means high needs of N ,P,K ...
Roots (or / and feeding program wasn't sufficient...Plant needed more ....),
haven't been able to provide sufficient assimilates...

100 % PS rates also means destroyed PS II systems ( Chlorophyll b ) ....
Thus also the high need of Mg ,to synthesize new CH b......
Still roots (or/and feeding ) failed to provide ...

Much light => much food ....
This plant is underfed....
Leaves started to dry up really slow , at the furthest away tip from leaf stem ...

Under more powerfull reds ,blues or UVs ,this type of plant will probably ,have a great difficulty surviving...
Maybe...

The other ...
Same feeding .... Same approx surrounding lights with a central one , like the one mentioned little before....


This plant ,doesn't seem to have a particular promblem with much red ,blue or uv....

No signs of either under or over nutritional issues....
And quite large plant ,I should say ....


Edit: Either most of times i get the purple leaf stem color as a genetic trait....
Or the P levels are maintained pretty low...
As I wish them to be...

Hi stardustsailor Can you tell me where I can buy heat sinks like Yours?

Theese heatsinks are from a local manufacturer in Greece.

Google is your friend

I'm using 2 180w Spectra grow panels from GrowLEDHydro. I have them both in a 8x3x9 closet, and when they're on the temps go up to 88 in the grow closet. And thats with 74 degree outside temps. Is this unusual?? The whole reason I bought LED's was to run a closed, CO2 system. I'm thinking about switching to the 357 magnum.

He tells nothing about heat sinks with this dimensions.

Anyway, 60pcs 1W in 3 panels of 20 two of them warm white 3000-3200k and one 6000-6500k for start will be OK? How big box I need?
How can I improve light spectrum ?

If the 660nm wavelength is so bad, why does Kessil, Illumitex, and every other big name LED manufacturer swear by them? This wavelength has been the magic bullet in my garden anyway, although it's been in addition to a 1000w Hortilux.
