Hi, thanks for the info. I ordered 12 lights. But I have a question, do you think I'd need a heatsink if I'm running them at 300mA? The heatsink will probably be the most expensive part, I'd like to skip it if possible

I have 2 drivers. I like the sound of 6 strips split into sets of 3. Then I could have 12 lights total.

I bought a knock off Mars blurple light before finding RIU and reading on DIY LEDs. I've already opened the light and installed 4 COB's but 1 blew out yesterday. I'm thinking of getting some 1' Samsung or Bridgelux strips instead this time. My question is can i really run 7 or 8 strips per...

thanks again for the info

Hey so do you just mix it in with every nutrient change? I just got a bottle i'm wondering if it'll kill the nutrients or anything, this stuff looks serious.

I'm new to growing just had one grow. But I knew i wanted LED's from the start. So i've done lots of research and wasted some money on blurple lights. I'd recommend strip lights either Samsung or Bridgelux. But if you go to the LED front page there are threads for Bridgelux the Quantum Boards vs...

Sounds so simple and easy. I want to get the hang of things, like LSTing and nutrients, then start upgrading my grow space. How many plants do you usually have at a time? I'm trying to get a feel for how many I'd need for just me. I smoke ½-1 ounce a month.

I like the look of the waterfarms and price when more. I have a normal 5 gallon bucket with airstones. How you ever compared the 2 methods?

Thanks for the recommendation. I've been adding 1-2ml of H2O2 per gallon every 3 to 5 days. I'm burning through it to quick I think. As for water temp, it's ~71 in dark and ~73 when lights are on

If going the beneficial bacteria route. How do I introduced the good bacteria? Is it as easy as adding a little sugar and Great White to fert mix?

I'm wondering if Root Excelurator can be used in DWC. I'm on my first grow and currently not using anything for my roots. I got a bottle of Great White (the powder) free at local hydro store. But when I use it it makes my roots kinda slimy and brown so I stopped using it. What do you guy and...

Ahh that's what I feared. This is my first grow I tried to germinate 15+ bag seeds only 4 sprouted and only 3 of those survived my noobness. But all 3 turned out male. I bought a few auto seeds a couple months ago. Going to start 2 of those next, they have to be female right?

I'm 8 days into flower, finally feel like i'm seeing signs of sex. Just want some second opinions, Are these dudes? I have them both in the same tent, if they are male could one have pollinated the other this early on? One plant another plant

Ok I'll keep it under 48V max. One last thing a few drivers have input V of 180 VAC to 480 VAC. If i'm in america i want the 90 VAC and above?

@Serva Thanks for all the links and help. @Randomblame Thanks for holding my hand and guiding me through combination wiring. I see now that wiring the main clusters in series i would multiply the Vf of a single strip by the number of clusters to find my needed output V. Then just divide the...

Would the current be different depending on which way you wired the lights. Like with the 2 clusters of 4 strips wired in parallel, the 5 amps would be divided by 4 right and shared between the 2 clusters. Just thought it through and I guess either way there is a 4 way parallel wiring to divide...

So if i'm growing peppers as well do you still think 10w/spft is Ok. I will be using part of my closet as a veg spot and also the permanent home for up to 3 peppers. It's a 2.5x5 area. I want 12 of the 2' EB series with 6 each on a HLG120H-24A (I want build 2.) So around 17.6w/spft think that...

Thanks for the reply. Yeah I was doing the math as though i needed 30-40w/spft i guess that is only during flower. I'll have to find a driver with a little less current

Newbie question. I'm going to be building a Veg light soon covering 2X2. I want to use 6 BXEB-L0560Z-50E2000-C-A3 (can't link yet sry), the VF is 22.1. Can i use a driver that is 24V if its CV, or is that too high? I'm probably going to get a MeanWell HLG120H-24B just to be safe though.

Thanks for the tip, I've been getting conflicting info on when and how much to defoliate.
