Forgot to ask, can anyone tell me if it is safe for the wires touching the heatsink. Since I have never run it for a long time I have no idea how hot the heatsink can get. I am just thinking it can get too hot and it will start melting insulation on wires. Also does the driver itself can heat...

It has been all fixed and both lights are dimming now. My friend who is an expert in electronics suggests that there was bad wires connection in these transparent connectors that are used to connect two wires together. It is a bit of strange but after getting wires in and out of these...

I forgot to say that KingBright supplied this type of a potentiometer https://www.ebay.com.au/itm/2pcs-RV24YN-20S-B104-100K-Ohm-Carbon-Film-Rotary-Taper-Potentiometer-Resistor/120915397786?hash=item1c271e8c9a:g:KfcAAOSwixtXQw7m:rk:1:pf:1

Hi guys, I need some help with this driver. I have two kits from KingBright of QB288s. Each kit comes with a heatsink, this driver, 2 x qb288 boards and a potentiometer. Plus all wires and connectors. I assembled one kit and the potentiometer was working perfect. However because KingBright...

I do not think it is true as a 1000W HPS probably consumes 1000W of electricity while a 1000W COB will be half of it most likely.

BTW, when I said they completelly dried in 48 hours it is not an exact way to describe it. After 48 hours they felt dry and all buds were kind of soft. Their stems would have not snapped if I had tried it, However after I moved them to a completelly dark place they were kept drying. And now all...

That's what I did by drying each harvest one by one above lights on a mesh shelf. There was some light reaching that section of a shed but it was no direct light, only what was reflected there. And I did not hung them I had them laying in a drawer, I have really some metal mesh drawers from a...

That's what I am afraid of that it especially that the place outdoor that I have for them only gets half of sunlight as the first half the Sun is behind my house. May be it is worth to wait till I get QBs. I have placed an order for them already and they are coming from China by DHL so I hope...

I did it with my first grow. I was drying above my lights in a shed. And I did the same with the second one but once they were almost dried I moved them into dark place. Some will say it is "no no" to dry near lights as light kills all good stuff in drying buds but nobody complained about my...

20g is good for a start but you can do much better. In my first grow I used 3 x 600W ViparSpectra(the same as yours) in 4x2 feet shed and I got about 25-28 grams from each of eight plants I had. All LSTed once. Second grow with extra ViparSpectra 1200 PAR added and LSTed 3-4 times I got from 2...

Hi guys, Just like the title says. I want to try vegging my plants outdoor for 4 weeks and then bring them inside for flowering. I am in Southern hemisphere and we have pretty short day here. Currently a day is 13.5 hours. but by the time I am ready it is most likely to be 13 hours of light...

With my last grow with VS(total of 3000W in four lights) I got from 2 to 3 ounce per plant. It is going to be more as I put cuttings outside and they will produce extra from a lot of popcorn buds on them. However I would not add it to VS achievements as they are sitting under the Sun now. The...

I would suggest not to measure runoff, measure EC in water before watering.

I used this one to germinate seeds and fix problem with roots. If you dilute it it won't hurt your plant. Ok, to be honest I do not know what happens if you splash it on leaves but watering with it diluted(like 1-2ml on 300ml of water) does not do any harm.

For QBs just go to Alibaba find the one you like and either wait for a seller to contact you with a price(if you have an account with Alibaba) or contact them yourself. Normally you can find there QBs as a full kit for 30-50% less of what HLG selling them for. Below is link to my thread with...

That's super funny. Thanks mate.

I would bin a fan but the lights I have(all viparspectra) are worth $1300 brand new. It is kind of stupid just to throw them away especially considering they have been used 1-2 grows only. I would keep using them but they add a lot of heat plus I do not think they are actually totally good for...

Has anybody tried to sell unwanted grow lights? How have you done it? I guess it would be silly to put it on eBay even if you do not grow anything currently but going to in some near feature. The same goes for gumtree. If I can somehow I would get rid of all my LEDs and use it to fund...

I would say you should get about 300-400g wet and may be 3-4oz dry.
