On the next grow I'll try some changes ...
-more WW in the spectral blend ,less or not at all CW and more NW instead ( WW : NW => 4 : 1 ) ...
-prune all the lower part of plant(s) ...Leave the 4 main tops (stalks )and some pairs of side branches at each main stalk ..
-Increase the CaO and MgSO4 ( CalMag ) dosage ...
-Have always "on"the air extractor instead of 30' /hour ...(more CO2 ... )
The indica dom didn't seem to like the UB's topping ...
Not at all ....
Anyway ...
The two panels with the violets have been removed..
(Now it is 130 Watts
at plug ... )
One week prior to harvest ....
The Sat dom ...
Under the unlensed ,cheap ,white ( mostly )one-watters ...
By now ,I'm pretty convinced ( based on evidence* ),that phosphor layer (remote or not ) and blue/violet chips is apparently ,
the best way to utilise led tech for plant cultivation in controlled environments ..
Not combos of different monochromatic (narrow band or wide band ) colors ...
Due to a plethora of reasons ....
* Evidence that support the use of phosphor & blue/violet leds ( white leds ) :
-Cheap leds & drivers used .
-No additional lenses .
- 45 x 45 mil dies ( @ 350 mA ) ..Aka "one-watters " used ...
-Overall wattage used up till now is low ..( less than 200 Watts at plug ... )
-Ganja2 got 1.6 gpw ...(with 132 Watts...He got 215 grams ...)
-plants grow vigorous and produce fine ...Both in quality & quantity ...
Now ....
I need no more proof ....
....
Next step ....
