No prob ... Use a 100k linear pot and you are set .
Yeah there are those growers on the forum that get WAY TOO TECHY with the spreadsheets and light formulas .... Rather kinda moot if you are growing in less than " optimal " conditions ( sealed room , temp controlled , etc. ) , many are trying to over analyze the specs of the light engines or power values.
For me , I keep shit way simple : target about 30watts per SQ.FT or so and you are growing weed ! No need for those 1000watt pizza oven lamps .... Less is more with these lights .... I grew 3 plants under ONE quantum ( qb304 ) 3500k S5 bin board with a shitty 50 Watt driver - nothing else........ It's in this thread , way back.
DIY isn't really that hard ( especially with these lights )
@robincnn and
@Stephenj37826
have done all the hard work by matching drivers and build support. I'm a kid of time when Kit building was something kids and adults did as a hobby ..... I built HEATHKIT shortwave radios ( never built anything like it before ) , radio shack projects , etc.
It's the handling of fragile components and learning soldering skills ... That's the tough part. I actually wish HEATHKIT was still around , they had some cool ass stuff.
