Dear mates, I finally did it. 3 vero 29 lights and one dimmable driver. I know that the connection is not optimal and it is better to run them continuosly but I was not able to find the cheap way to do so... The parameters of the driver are: U = 42V I = 5.6A So each LED gets almoust 2A which...

i am on the way so can not find the characteristics of both. you have 2 ways to connect such things as leds (and other things needs pwer) - parallel and series. Series will multiply voltage, parallel will multiply amperage. lets say you want to run 10 cobs series while each takes 40v and you...

Hi there :) flowering needs more of red so you need 3000k ones. you have to calculate the number of COBs based on your room as more does not always means better. my example is a universal light. i am planning to use one 4000k and 2*3000k. 4000k for vega and 3000k for flowering. one 3590 will...

Thank you very much, mate, The efficiency is my next level then :) Now I will start my first expiricence and it will show the rest. right now I am using UFO china led (150W on the paper - ~90W in real) which brings me 33g per pet. Hope my results will be better with COBs.

Thank you Supra :) and the efficiency is more for electricity consumption? because the delta in cost difference is ~$70 so i will have to burn led for 30 circules to depreciate the delta vs the cost of the electricity burned with higher consumptiom on vero 29. anything else rather than...

Dear Co-wokers, can you please have alook into my calculations. The delta in the cost of the solution is $78. The electricity is not that expensive in my country. THe target is to get the light ~ 20K lumens. Any comments will be appreciated. Vero 29 Cree CXA3070

Dear Supra, mates, I want to DIY the solution for my cabinet which is 1200*600*2500mm. Basically my need is a lamp which will cover the full square. I red about the overlightining so want to know more about the appropriate wattage/lm per square meter/foot. I am choosing in between the Cree...

saw it. your garden is my dream. I am leaving in apartments so can not affort such dimentions :) 1-2 plans maximum. By the way my Big Bang Auto from GHS had skunk in the genetics so the odor was reallyh strong. Even the carbon filter was not able to sort it out :)

Hi Man! thank you for your hints. I am planning to DIY the led light based on the Bridgelux Vero 29 diodes. But this is in the design phase. I must say that I have got 35 grams of pure hard "heads". But this is a low amount, I agree. Looks like the roots have been overwatered from the early...

Now it is cut!

Last day alive :)

amazing, amazing family :) great result.

Dear Supra, can you please comment point 2? for me it mainly a grey area why, following my logic, led consumes the same as hps? looks like lumens are the same with the same wattage of both. what is oost in my logic?

i am using 147w china made ufo led + 54w china made bulb + 2*18 watt osram light

would be great to see your results once available

Hi Supra, i am new to custom led culture. sorry if my question is off the topic. maybe you can point a right place to digg the info. i have checked the sites if the led distributors (cree, bridgelux) and now i have following (sorrynif dummy) questions: 1) vero 29 by bridgelux has 10k lumens on...

TNak you, mate! Good luck in your grow.

Hi Bro. I am using LED 150 WATT (UFO). have plans to buy a 400 WATT one from LG LED.

Fresh photos of my garden. The issue has been decreased slightly since the pot has been flushed with water (low PPM). Looks like it is not possible to fix the issue totally and the harvest is near. can you please advise on when I have to start with Ripen?
