Fourways, Jhb

I suspect membership here will see some growth in the coming weeks.

If that's the case this forum software really needs an overhaul.

What do you suspect the outcome will be? Personally I think the con-court will favor with the state.

Dunno, think the site's data capabilities has some bad juju..... keeps on blocking cause: file size....

 

I haven't got around to it, but will take new pics tonight.

 

P.S. keep us posted on today's concourt, I can only catch the highlights tonight

It's because your  images are massive resolutions, downsample/scale them.

How far are the lights?

Yes it was not a negative insane, I remember having one plant and being able to smell it from my drive way

How many carbon filters do you have running? The smell must be so insane. 

What the hell is wrong with the plant in the bottom left in the last pic ? Looks kinda dead

Looking good, what the final pot size?

They're in the final pots. A little worried about whether those 20L pots will be enough for the organics to be honest, especially without any substantial feeding... but will see, perhaps I may have to get some Biobizz as backup. The hydros will be fine.

 

Will be flipping to 12/12 today

What are you using to keep your hydro cool ? I've never grown hydro and will be attempting / building my first hydro setup in the coming weeks. All the hydro coolers i've looked around for cost in the region of around 9K...

Your hydro babies are looking good, 420SA. Really shows the power of water-soluble nutrients, lol.

 

I've seen CO2 generators like that one before, greenkush; do you have any idea how much CO2 they generate in total (per bottle) or as a function of time? I imagine these biological processes are not going to be quite so efficient at delivering CO2 as just slow-releasing a bottle of the stuff.

They're not efficient at all, but they're cheap. So you can literally have has many as you like or just make one in 5mins. Here is a article showing some rates, ignore the mosquitoe related stuff

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2984570/

Don't get me wrong I do know of the benefits and yes it will make a difference but its another cost I would just prefer to avoid as the plants can do without added co2

 

Interested to hear about your R50 co2 generator though

Yeast+sugar+water + 5L water bottle, tubing, and a small inline valve to adjust the release. yeast eats suger produces co2 byproduct, R85 for bulk active yeast macro for 24packs 5grams, it'll last you a few months

Growguru sent the bottle to me to test out. No way you'll see me paying R250 every 2 weeks for co2. Adding co2 to a grow like this doesn't seem worthwhile to me anyway but hey... let's see

co2 to any grow is beneficial immaterial of the size. I'm sure you've read articles on the subject so I wont copy and paste but they all over. That being said you can easily just build your own generator for like 50R.

You'd need to get it at around 1000 PPM. You'd need to calculate the volume of your tent, then the release pressure of that bottle in order to verify that are indeed getting it to the required concentration.  For your size tent which looks like 1.2x1.2 ? I'd go with one of the mycobags they last 3/4 months. Those bottles are a bit gimmicky in my view and only last for two weeks at 250R a refill. 

i'm busy setting up a regulator with a bottle, however due to the costly nature of co2 monitors ive had to work out the required release pressure along with the timing intervals in order to compensate for my extraction fans. Ideally a nice co2 monitor would be awesome, but at 245USD meh..

Sent you a PM.

Veg-W09, Flower-W0. Fired up the 400W hps and flipped to 12/12

Administered a strong concoction of organic and chemical nutes. Was quite impressed with 420sa's reference to the grower who fed 6 times daily to root bound trees, figured I'd give it a try considering 8/12 of my plants are already root bound and thirsty. Can't manage 6x, will settle on 2x daily.  

Got the 400W lamp working off 600W electronic ballast on medium setting. Any one have a recommendation on this? Room is filling out nicely, preflowers already evident on most plants, no sign of balls, but really haven't looked hard enough.

Will perform some LST over the coming weeks as they stretch and show sex. Plan to produce a few seeds and crosses with the AK 48, if I have a worthy stud.. will see

Yes you can run the ballast at that, I did a few times (it was mine  )

Still aiming at the cannabis community, but a bit more next-level.   QBs are great, but the Chinese are all over that bandwagon now.  

 

Hate to break it to you, that is where HLG originally got their QB boards manufactured, by Bava or Hansion.

 

Sure...   I think you misread. I was saying that a new production run of QBs wouldn't be a good idea now. It was a good idea when I did it in June 2017. But now everyone in Shenzhen has caught on, and is sitting on stock of HLG clones, ready to sell. I would rather put my effort into designing something that you can't get from China (yet).

In other words be ahead of the game, which you have been. Have you looked at mixing cobs with some diodes?

 

Sent from my ALE-L02 using Tapatalk

Mixing cobs and strips is common, even adding some far/deep red for emerson effect.

Looking at the S2W or Q series but they don't have stock of Q series yet.

 

I have a Secret Jardin DR90 tent it's only 90cmx90cm so I'm limited in options due to the size of some lights like fluence

 

 

Do yourself a favor go to builders, buy some metal tubing of your choice, work out the wattage you want for the room, then buy some of these https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SI-B8V521560WW/1510-2221-ND/6624005 and then buy a couple of mean well drivers to power them, depending on what wattage you want to run each strip at you can build yourself one heck of a powerful light for very cheap in comparison to these other products, you could even go for the influx (new) https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SL-B8V7N90L1WW/1510-1357-ND/5958916, more efficient. You'd most likely need like perhaps 4 maybe 5 for your grow area? So that's like 1730 for the strips, then just find the mean well LED driver you want. This way you can build the light to your exact needs and add extra if you want.

 

Thanks this is great advice. I will go do some more research on this topic.

 

 

I should add digikey will deliver with UPS World saver I believe which is too your door in a few days, purchases over 2K is usually free. You could build yourself a 500 watt LED (run each strip at 100 w), get U-Channel from builders, mount the strip the flat side of the channel, you could then also get some thermal conductive tape to fasten the strip to the u-channel, get some smaller heat sinks if you want to place inside the channel, even mount some fans on the ends to create an active cool environment, your imagination can wild. You'd just need to see the efficacy vs power ouput, I believe some run them at 75% as the sweet spot, others burn them to hell at 100 watts or more if they can handle it. A meanwell 600H-54b  (https://www.mouser.co.za/ProductDetail/MEAN-WELL/HLG-600H-54B?qs=5pLaOnqdcwNCvIm%2fbJMCow==) is about 211$, 11.2A ouput.  

My new light im building runs off of 3 600H-48B's

Two of these in that would be perfect https://fluence.science/store/ray-series-led-grow-lights/ray22/ - 370 $.

That's the problem with half these stores in SA, they advertise stuff but never have products. I've resorted to actually just importing all my grow stuff, local stuff is just so sub-par. Hydro shops still punting shitty burple leds for 10k lol.

You mind if I split this post into a relevant topic under the LED lighting section guys?

 

You welcome to move it.

 

I've done some more reading on the SANlight and their optic lenses is really cool as it doesn't create shade. I hear those lights can easily last you 10 years plus. Just the damn price

Which one are you looking at?

For the price of this model : https://hydroponic.co.za/hydroponics/sanlight-p4w-led/

I'd rather just go for a fluence ray 44, I have two on the way from the states.

Everyone is cloning everyone, if you can get a product at a fraction of the price and its genuine products then go for it.  Unless you are an photonics engineer, by the time you've come out with something china has already done it 10 fold over. Personally the lights themselves are very easy to construct (I've done a few builds myself), I am busy building a new project which is entirely automated (light wise), but at a fraction of the cost in terms of components, using custom coded firmware (by me).  Fabrication and design is where is at, the actually light source is so saturated with options now, If i was going back to the drawing board i'd design a unit which is easily expandable similar to the fluence rails.

Yeah, vs. Sanlights, the QBs are a bargain.  Efficiency-wise, the Sanlight website claims 2.9uMol/J module efficiency (i.e. before driver losses). The only other manufacturer claiming 2.9uMol/J is Philips GreenPower, and those things cost a fortune.  Judging from the pictures, it's a 2 warm white : 3 red (660nm) spectrum, using Oslon SSL 150 with secondary optics.  Their secondary optics are pretty cool - more even rectangular distribution.  Oslon SSL radiant efficiency is 59% for reds, which is superb, but OSRAM's best white is only 151 lm/W (vs. 185lm/W for LM561C driven at 3/4 power, for same colour temperature). The estimates I've seen on rollitup for LM561C (QB) are between 2.4-2.8uMol/J.  

 

I am changing direction slightly, with my next order, which I'll discuss in a few weeks, when it's more certain.  (The rand is tanking hard, and will probably kill my plans if it reaches R15.50/$.)  Still aiming at the cannabis community, but a bit more next-level.   QBs are great, but the Chinese are all over that bandwagon now.
