Veg bloom or dual

Hi guys. Bought an led light after wanting one for ages and I'm not disappointed the heat difference is night and day and I can see my plants being far happier for it.
My light is a 300 watt kingbo duel optical lens and has three settings. All blue all red and both which is kind of purple.

Question, is it better to stick to the specific modes for the stage of growth or is just going dual spec going to be overall better.

My thoughts are dual is better but I don't know if I'm right or not..

These 2 day old seedlings seem to be loving the dual spec

I'm still getting my grow box calibrated, but from what I researched (several sources) you won't notice anything or you're not able to identify any changes with both spectrums during youth or veg stages, however during flowering it's been said that using both spectrums can cause noticeable differences.depending on the strain. I would imagine it's somewhere along the lines of growth and concentration on it certain areas of the plant depending on the spectrum it receives at certain time rather than both all the time and etc. I'd be curious to see your results.

Yeh that's what I'm getting at. I do intend to use both spectrums in flower but for young seeds and vegging I'm wondering is there any point at all in adding red.. May even be slightly detrimental in terms of longer internode. Yeah Ive switched over to far blue now for the veg stage..
Tbh the effects and differences are probably minimal
