I did the same on the water before i gave it to them. I used PH down and set the PH at 5.9-6 I believe that while previous watering, before I had PH meter, I gave high PH level water to them. I have never watered them till the runout. so I believe, for the next waterings, I need to give them low...

I checked with soil meter and the reading is 7.0-7.5 untill today, I didnt have a chance to measure PH either in soil or in water before giving to plants. I thought the same, maybe it is because of PH disbalance. I use 12 liter (3 gallon) pots. First I started watering with 250ml, then 750 and...

Hey Just wanted to share about my build and also hear your advice For 2'x2' build, I decided to go for 150W build and got Bridgelux EB gen2: 4x 3000k, 3x 3500k and 2x 5000k of 2' strips. As I realized later I could do it even with 7 or maybe 6 strips, but it can only have positive effect and...

whatever you doing is series wiring. if you wanna wire them in parallel take the positive one coming from the meter, get kind of wago connector to "split" the wire and when you get 2 wires, put it into the positive of both lights. do the same for negative. in short, positive wire should be...

Does anybody know how exactly this dimmer is made? As I know when you use N number of drivers The resistance or dimmer potentiometer should be 100/N. As I understand all the models have same kind of linear potentiometer. How does it operate? in case of single unit I understand, but when some...

and one more question please. as I researched in datasheets, HLG and ELG are almost identical since I'm gonna work them on 220vAC. So ELG-240-48a would work perfectly fine as well, right?

HLG-240-48a costs around 65$ and I have a chance to get XLG-240-HA for just 26$. I thought I would save some bucks but I got your point and you are right. Thank for help

thanks Has anyone else tried them out or know for sure? I don't want to fry those boards. If XLG-240-HA will work for sure,I will order it. Thanks

Guys, I got 2x bare boards without everything. I want to get driver for it. I know HLG-240-48A/AB or ELG-240-48A/AB is the best choise for them but they are pricey and wanna know if there is any cheaper solutions out there. As I know they work 47-52V @ 500=2700ma. What if I get XLG-240-HA...

And guys, if there is no way, I can get them work on normal power supply, can you tell me which LED driver will be best for 5x Citizen CLU048-1212? (want to get 60w from each of them) Also, is it possible to run different kind of COB or strip light which isn't same volt / amps as CLU048 s? for...

Guys I've been researching for some days and have several questions about LED drivers. I'm going to get more lights step by step. At the moment I have 5x Citizen CLU048-1212. 2x 3500k, 2x 3000k and 1x 5000k. As for drivers I dont know what to get. I want to get around 60w from each of them. Is...

Gen 5 and Gen 6 has the same price on cobkits, so I will go for 6 I think. also, in case of these leds, will I need any additional IR or UV or any other type of LED for full coverage of necessary spectrum? What color COBs should I get? I thought of getting 3x 4000k, 3x 3500k. Will it be...

I dont even know. Do I need dim? whats the advantage of it and how can I use them, whats the point? I said about water cooling for 2 reasons: 1) I already have items for water cooling parts, aluminum radiators coolers and so on for free (my brother has PC shop and has PC cooling parts). 2) I may...

Hey there I'm kind of newbie and have questions guys. I have 4x4x6.3(feet) tent. I need light to grow 2 plants in there simultaneously. I read some threads here but still some things are unclear. 1) My first question is about cheap Chinese COBs. As advertised they are 50w each and is very cheap...
