Greetings everyone :D Lately I have been compiling the elemental ppm measurements of different commonly used hydroponic fertilizers and thought I would share it with you all. Hopefully this will help some with comparison in order to notice similarities as well as differences. GH micro 7.5ml &...

Hello everyone :leaf: I would like to know if it is advisable to add dolomite lime to a soilless mix with a coco coir base. I currently have a base mix I put together that is nice and simple but I have not added any rock powder minerals to it yet. It's basically a play on Coots Mix: 1 part...

It is cool see you have messed with all of those Kelvin ratings! Were there any other differences you noted between the three like internode length, density, and resin production? If i might ask why do you like 4000K boards best? Thank you for your thoughts.

I did! I came to the conclusion that I would go with straight up 3000K LM301H diodes and just see how that works out for me. Seems like it still has plenty of blue in the spectrum anyway. Although I have heard 3500K works fine all around I'd rather be sure with 3000K. The trend with 3500K seems...

Thank you for chiming in. I've been going back through this thread today and that definitely seems to be the general consensus. Now that I've come to the conclusion of going with 3000K Samsungs I need to decide whether to go with Kingbrite again or to try out Meijiu which seems to be pretty...

What's up everyone! I jut converted my 2x4 veg area to a 240w Kingbrite with LM301H at 3500K. I got that Kelvin rating assuming it would veg well but would be able to flower decently for a couple autos every once in a while. Now I want to upgrade my 4x4 Flower tent to LED as well so I want to...

Thanks for chiming in. LM301H from what I understand is an updated LM301B that is supposed to be slightly more efficient, but from what I gather they are both great diodes. I have been looking at those Rspec QB96 builds. They are awesome but I am still questioning if the 660nm chips are worth...

Hows it going everybody? I've been perusing through threads for the last few weeks getting my LED knowledge together. I've already upgraded my 2x4 veg rack to have a two 3500K LM301H QB 288's running at 240w. Now I'm about to upgrade my 4x4 flower tent with four 288 boards to replace my old 600w...
