This is just a word of warning for anyone who ever considers trying this company. I bought a packet of their Candyland fems earlier this year. Had fancied trying this strain but not enough to pay the amount Ken charges so I took a chance & bought from Garden of Green. I maybe naively just...

I’ve been running cxb3590’s 36v (CD bin) for about 3 years now & I am noticing that plants cloned from the same cut under certain cobs consistently grow less vigorously than under others. I suspect that the cobs have diminished a bit over the years. I’m not looking to change the drivers...

I can't actually see them on any of the leaves & I'm not seeing any flying critters so I'm not sure what is leaving these marks. Can anyone tell me what these marks look like they have been caused by? Thanks in advance

I am trying to work out which will be the most effective. Coconut butter sounds like the easier to make & use. Is RSO just a more concentrated product or can I get the same effect as RSO out of making & using coconut infused canna coconut oil? It’s primarily as a sleep aid but I want to get as...

I'm considering giving candyland a go. It's described as being sativa dom but considering the parents I can't see how that can be. Has anyone grown it? Did it turn out more sativa or more indica?

I ran a small dwc set up a few years ago but due to space constraints, heat & lack of experience I gave up on it. Mainly, repeated cases of root rot. I now have more space to grow in & a bit more of a budget. What ever I go for needs to be fairly quiet. The room that the set up will go in has...

The last time I looked around it worked out to be cheaper to import pin fins from China. Does anyone know if the price has come down on these in the UK or EU?

I’m expanding my grow space a little & need to add another 4 cobs. I already have 12 x CXB3590’s CD bin which I’ve had for a few years now. Ideally, I want to at least match their efficiency. Thanks in advance.

I’ve got a problem with my grow that I haven’t seen before. I know I have some yellowing tipping going on & am today reducing the ec level. The leaves are turning up & some are going a bit brown & some are going a bit purple. I wouldn’t be surprised if the night temperature is at least partly...

I’ve not made oil, butter or any other extract before. I have a fair wedge of trim I want to use to create some sort of extract. The intention is to ingest what ever I produce, probably as a sleep aid but also as a general health improver. My question here is what method gets the most out of...

I built a couple of panels using 4 cxb3590's per panel a while back & spaced them out so that when hung in a 2x4 the cobs would be centered in each square foot. Mathematically this seemed to be the best layout but in practice I get a hot spot down the center of the 2x4 so I'm considering a...

Looking for a little help as usual. Ok above is a Samsung F-Series strip build that I put together for vegging some plants. Now initially I wired it in series & it worked fine. I then realised I hadn’t checked the maximum number of these strips than can safely be wired in series. Digi-Key...

Ok looking for a little help here. I have a terrible memory & have forgotten the name of an implement/tool I have seen used by a number of people on this forum on their DIY strip light builds. Because I cannot remember what they are called I cannot locate one for a build I’m doing soon. I’m...

Just wondering if they are just a cash grab like the C99 re-issue or are there any gems in there at all?

Hoping one off you more learned characters can help me with an aggravating fault I have with a DIY CXB3590 panel. I’ve had the last 2 cobs in series not light up twice now. Before I explain further I should probably give the spec. Spec: This panel is about a year & a half old & to date has...

I know I know there are quite a few of these. In this instance my question relates to a more specific circumstance. A friend has asked me to build him an LED system to replace his 2 x 600w hps system which will live in a 4x4 tent. He regularly ends up toasting his tops buds & has seen how...

Morning all. Hoping someone more learned can help me out with this. I have built a number of cob panels using HLG B drivers. I have recently just completed my 2nd Samsung strip build also using HLG B drivers. In general, all good but the one thing I have noticed is that none of them actually...

Can anyone tell me the minimum & maximum lux at canopy when flowering with COB LED’s? I know that ppfd readings are more accurate/appropriate but I don’t have a par meter & I’m not in a position to get one anytime soon. I do however have a lux meter app on my phone. Probably not the most...
