We've all been there...changing, upgrading, reading, comparing, counting pennies... Imagine doing it without forums like AFN or any valid info. Being older and retired and growing to please myself, I like getting my monies worth to settle that nagging age-old question we all have...."how'd I do?".
I slowly changed from 1000w hps to led years ago, going through the blurple stage...(glad you missed that) and into led whites. Still I wanted quality grow power at my dollar value.
Actually, blurples were good enough to convince me to change but I was quickly into the cobs/qb groups. Most upgrades to my grow area were done by a budget of $150 per and over time and gifting from my lady, I've ended up with a mix of everything which gives me the adjustment I like as my flower room always has ladies at different stages. Guess what, they all grow weed! Oh you can spend more money but I find it more fun to piece meal it....
Final thought...one of my primary lights is a mars hydro ts1000...at 150w under 150 bucks fits in well and has definitely shown its value. I run a 3x4x8 area with an accumulated wall pull over 550w. Although I still run a blurple as a supporting role and a small hps for heat at times, it's the white leds of cobs and qbs that I notice plants moving toward.
