Well me being so impetuous, I already ordered them. I dont actually need the light, I already have cob setups. I ordered it more out of curiosity I think the forward voltage for the qb 304 is 1600ma and the driver they are sending me is a 2100ma, would I have to wire the panels parallel? Is...

I just order two qb304 boards with and hlg240h 2100b from China through alibaba,hope they aren’t fake, ordered my cobs the same way and they were legit

I know a lot of people order their quantum boards off of growerslight.com, has anyone ordered their qb boards off of alibaba or similar sites? For $135 u can get two 304 boards, Heastink, hlg 240 2100b driver, everything needed to make a light just like growerslights.com. Are these a waste of...

Greengene actually messaged me about this controller, I’ll probably be ordering a hub and several controllers for my other light

When you say + and - on the coralux, do you mean I should splice into the dimmer wires that connect to the coralux? I have that same unit on the way, should the driver be plugged into always on?

OK that helps a lot thank you

I spoke with meanwell and they said as long as the relay cuts power to the driver I can use it, I have also looked over the data sheet and it’s still a little unclear. This is the link for the iot relay https://www.sparkfun.com/products/14236. Do I just simply plug my driver into this and then...

I just purchased a coralux storm led controller with 10v converter and an IOT power relay. Will this work to dim my hlg 185 down to zero and eliminate my need for a separate timer?

I have a four cob light running on the hlg 185h c700b. I just purchased the coralux storm led controller with the 10v analog converter and it was only after ordering that I realized that the storm will not dim the light completely. It is my understanding that to get the light to dim to 0 percent...

i have a few seedlings that dont have many roots yet, i was just going to try pouring some over the rockwool and hydroton just to try and help them along. there are no roots in water yet

do u mix the root and the foliar and then bubble for a day or mix and do a root drench

so its no good for the dwc but i can at least use it in coco to an effect

all i ordered was the roots pack im seeing some people mix the roots and the foliar pack. i know next to nothing about running bennies

does anyone use bennies with jacks? in either dtw coco or dwc. i have been running sterile with pool shock and although my roots look great i feel they could be better. i just ordered some og biowar and was wundering if anyone had any insight

Keep It Simple Stoner

does anyone else have a problem with lower leaves dropping off when adding extra epson salt? im about six and a half weeks into flower in dwc with jacks and anytime i add more than fifty ppms of epson lower leaves start dropping off

different strokes for different folks, i myself use a 20$ ph meter that works well enough, a BL meter is on my list of things to get. i could be wrong but i believe u can only get down to 7 ppm or so with a basic RO with the RODI u get 0 ppm. i am also on a well with a water softener, even with...

you def need a reliable ph meter, strips are not accurate enough. 400 ppm for your source water is pretty high, i would get an RODI and start using a coco perlite blend... as far as plant training techniques for larger yields, topping, fimming and supercropping all will help to do that. whatever...

that sounds about right. my water starts at about 6.4 and ends up about 5 maybe a lil bit lower

i have a sunset sherbet clone that i vegged for about a month and has been in flower for about three and a half weeks and im getting some brown chlorotic spots on the edges of some larger fan leaves. im pretty much using jacks 321 in RO water under three cobs. i was thinking maybe magnesium but...
