...step by step ....
Closer ...

System Check completed .....
Initialising ...
..The "veggin' " one ....(Trully ...Blinding one ....)

........All three .....

Camera White balance set to 5000K (daylight ),for the next 3 pics .Manual aperture/shutter speed ,ISO,etc settings where the same .
...Spring towards early summer ...(vegging: 700mA ,2x flowering :~250mA )

....Summer ....All at 700mA ....Max power ....

.....Late summer to autumn ....(2xFlowering : 700mA,vegging :~250mA ) ....




Ok.........After this test grow .......
......


Time has come ......

Annnnnnnnnd now i'm ready to pull up a chair ........subbed and good luck friend

I'll give my best shot ...
I promise ...
I learn fast ...

I meant "goldhand" in Greek [hrisoheris]

...i thought i shouldn't write " the man with the golden hand" ...

but just realised that "goldfinger" was the bad guy...

I think i will just call you Popeye

Ok....Χρόνια Πολλά,παρεμπιπτόντως ....

Plants of this test group (all White Russians ) were topped* yesterday ...
For two more weeks they will be kept in vegetative state ,before turned into flowering ...

....

* First(node's) pair of branches removed ,tip after 3rd node ,removed ...
Branches from 2nd & 3rd node left ,to become four "main" stalks,per plant ...

Yep am subbed too for this!

Do you find the pc fans move enough air? I am fed up with noisillating fans

As long as they are more than two ,yes they move enough air ....
Personally I use from 3 up to 8 fans ( cheap $5 ,120 mm ,12 Volt ) ,depending on the number of plants ....

Sometimes ,I get some leaf tip curling ..(Dried up ,'cause of the non-oscillating stable air current ) ,but only when plants are young ...

...Still ,they are a bit noisy ,those pc -case fans , also ...

Third day after topping ....
Recovery ,is beyond ideal ....
...
Although there might be,also, a slight pH problem ....
Some curling is there ..(' dry-ups ' )

Edit : Also ,I do not like that much ,the dark green leaf color,of two of them ....
It "yells " excess Nitrogen assimilation ...
Which might be a sign of being males ....

Some more from the first "test group" of the 3 regular (from seed ) White Russians ....
-Distance Leds-canopy : ~ 35 cm
-Central-"vegging "- box ,set at ~650 mA ,rest two-"flowering"- at ~350mA.
-Cycle : 20/4
-Nutes : Mineral Salts .Ascophyllum Nodosum Extracts.Mix of AminoAcids,Carbonhydrates and Vitamins .Betains.ASA.
-Water : Tap water .Bad Quality .

....

Boxes seem to perform fine ...

i followed you for a long time...you have really good experience for leds..

What dimensions your grow tent ?

108 leds enough for that space ?

1x1 meters "floor" surface ... ( ~ 3' x 3' )
1.6 height ...

108 Oslons for 1 square meter ?

More than enough ....

Up to 7-8 plants can be grown at that space ,with those three GD-SDS boxes ...
But I'm pretty satisfied with one or two plants ,anyway ....

wow...quick reply

may i learn your leds beam angle (probably 80) and consume wattage ?

thanks for reply

Yes, 80° ...

Everything*,at max settings** ,have a power ,a bit less than 300 Watts, at plug...

* .... "Everything" ,stands for :

-108 leds
-6x fans (48 V ,0.05 A )
-9x buck drivers ( Recom )
- Main Power unit ( MeanWell )

**..."Max settings " stands for :
All 6 fans driven with 57 Volts -at their max ( adjustable range : ~ 39-57 V )
and all 108x leds driven at @700mA .. ( adjustable range : ~140-700 mA )
