Guys going into my 1st feminized grow to flower I ...

Use both switches/modes 👍 i do it too 😉 i learned that the only different is that more blue gives you less strecht and more leafs, more red gives you less leafs and more strecht. But that is only for the first 2-3 weeks, later its depends on the light power (par not Lumen!) As long as you use a full spectrum you dont need to really care about more red or blue. (But more red ist always better for bloom) so it only depends on the Power of your lamp 😁 if you have enough power (30-50watt 1 saquare feet) only use bloom, otherways use full power 👍
