I put together a 1000w real wattage build. I want to thank all of you for the tremendous help.

I ended up using the Bridgelux 180lm/w 44" strips 20 of them.

Way more bang for the buck.

I dont think there is a light out there that can touch these as far as value. I have a bit of lead time on the order, but am pumped. I think I got everything done for right around $700, but I'll have to pull invoices. I will send out details when I have a bit of free time.

A little late now, not really unless they're shipped yet, but I went for 3500k to span the entire growth.

I am just curious, not like I'll ever build one. Seems a mix of 3K and 4K would be the best coverage of both ends looking at the spectrum, not much gain with the 5.7K

How much did the 44" strips cost and where you get em?

I wonder if I could make a go at it by custom building these for growers here in Nor Cal. My retirement only goes so far. I can do the math...lol

Time is precious @raratt if you got it, make the move!

I work in Finance and have long hard days filled with math, but zero time to capitalize on the knowledge that brought me to this build.

@raratt you were of no help throughout this entire thread... I wouldn't buy shit from you.

I was thinking of making my own grow room design and building conpany. It would include undercurrent system, hpa, lpa and coco. I would include diy lights or off shelf. I had ideas for art installation grow peices for art as well as growing.

It's just hard for me with my back to get things going.

I think there is a huge market for REAL fertilizers in the MMJ scene.

I have some knowledge in chemistry and just ripped off the top fertz from Botanicare, Fox, and General Organics - exact clones.

Buying their products are over 10,000% markup.

What a joke! They are disrespecting growers.

I see that and the lighting game as very big opps.

I have to sign off for the night. I'll post the build etc this weekend. When I get everything in, who knows, maybe I'll have the wife pull out the camera and put up a build thread.

What are you using for nutes?

What coast are you on bro? I've got a strong back and am tired of the damn rat race, lol.

There are two electronic formulas that you should keep in your pocket, Ohm's law and Watt's law. Ohm's law is E/IxR where E=voltage I=current and R= resistance. So if I have a circuit with 10 volts applied to a 10 Ohm resistor the current will be 1 Amp (10/10=1) Watts law is P/IxE P= power (watts) I&E represent the same things, current and voltage. If I have a circuit running at 10 amps with 10 volts applied the wattage is 100W (10x10=100). In a parallel circuit the sum of the current in each branch equals the applied. As long as the resistance in each branch is the same the current through each will be the same. So if you are getting a driver for 4 strips that use 5W each you would need a 20W driver. Computing current in a parallel circuit with differing resistances requires using the reciprocal of the resistances which I'm not going to get into. I edited this to take out the reference to the series parallel circuit.

Resistance in a parallel circuit is not proportional, in that if you mix resistances, say if you run one strip on one leg of the circuit with the other legs running 2 strips the current in the single strip will be greater than half of the other legs. Computing current in a parallel circuit with differing resistances requires using the reciprocal of the resistances which I'm not going to get into.
This is what you're looking for, not just you rarrat, I have a feeling you've seen this before. Just remember, calculations are different between series and parallel, so a bit further research is necessary when wiring.

I have, I was just keeping it simple. Using two strips in series was a bad example, because then you have to compensate for voltage loss on the first one and that's a whole new ball of wax. It has been a long time since I did the basics.

I didnt forget about everyone. I have been slammed with work going into the holiday. I fly out on 12/22 for vacation and will post all the promised info while on the plane.
