The LM301h diode is the best currently available and has the highest available efficacy. The LM301b model (what you will probably get with Spider Farmer) are a generation old, but still work quite well. The h model is only 10% more efficient.
Samsung now has a new model that I haven’t seen used yet. It is the LM301h EVO. I don’t know if it is in production yet or not. @dbrn32 would probably know.
So as far as how good the Samsung is, what does that translate to in muh grow?
More density? More stank? Bigger flowers?
Sorry for the ignorance.
I’m old school. Last time i grew it was slam them with hps “lumes”
And they are searching for light just a little more than I thought they would lol …
This light was recommended to me by @Graysin a while back and I love it ,I was actually going to get another and was upset they went out of business ,I believe kingbrite makes a 480 that’s very comparable to this one
Those little ones are searching and I even have a 11” magnet bar light right above them , because of the other plants I can’t lower the light above any more lol
I would recommend hanging 4 to 6 spider farmer sf-1000 lights above your grow. Each is dimmable which allows you to have a good even coverage without big hot spots.
Each of my lights is currently made up of 5 of the SF-1000 lights. I made an aluminum frame for mine that allows me to move the lights around individually as well as soon each to it’s own level.
Each light fixture is 48x30 and able to hold 6 lights.
I’m also going to add the extra uv lights from SF down the center.
