Hard to judge dude, to me the buds look a little smaller but I haven't done this strain previously and the ones I saw from the same pack of beans under my mates hps were also small buds.
I also struggled with low temps first half of flower.
I will form a better opinion over the next few runs. Don't want to jump to conclusions when I haven't provided the ideal environment or comparison.

My previous runs with the v1 kits in 3k from HLG were with strains like incredible bulk and blue dream, which are both heavy yielders and really chunky bud structures. I think the banners are known for high thc rather than heavy yield , but don't have a lot to go on.

Good choice. A lot if us use Megacrop as well for nutrients, Makes growing easy. THe "B" at the end of that "C1750B" number means you will need a potentiometer wired on the the leads for dimming ( external pot ). The "A' at the end "C1750A" would be a built in potentiometer for dimming. I prefer the "A" but I mount my drivers remote.

Sorry I’m a little confused on what you mean? So there are other parts ? Or something different? Can u suggest a build for 200$ that would be easy for me to put together? Thank you sorry I just am struggling

Need everyone’s thoughts , I am running 4 qb on a meanwell supply and I noticed that they were off . I thought it was the timer . Plug it into the socket directly and it powered all night . The next day they are off again after only being plugged in 30 minutes. I disabled and took them down. Everything else was working fine without them. My thought is it a bad power supply?

I had one do this just before it failed completely. Meanwells have a 7 year warranty though so you can get it replaced.

I finally got around to replacing the 240H-C2100b that has been driving my QB 304 boards. The 240 was a substitute for a 320H-C2800b that died some months ago. I was given a 320H-2800a as a replacement ( through a dealer, not warranty ). I figured today was a good day as my Sugar Black Rose are in pre-flower stretch. Ladies are looking good!
