  1. A tent is a tent. Buy it second hand there is lots of stock in the 2nd hand market. Lots of people getting out of the indoor seen. I would rather invest in a proper greenhouse.

  2. I found this is really insightful, especially how certain amino acids increases a plant's natural resistance to powdery mildew and botrytis at a cellular level.

  3. There is a free app in the google play store, PPFD Meter - Grow Light Meter - It gives you the DLi (as well) - It uses your phone's camera sensor, so I would suspect that the better the sensor on the phone the more accurate the app would probably be. You can google Bruce Bugby or search youtube he has 1 particular presentation on light that explains a lot on the subject.

  5. Hey buddy, no need to get excited. Obviously a kak led will give off more heat than a good one. I never said it would not. Good LED or KAK LED, a heat sink does not make the heat less. It simply spreads it - and that I have learned prevents foxtailing The lm/w is a great indication of the efficiency of the light. There is a theoretical maximum that a 100% efficient source can deliver. Some of us likes to get technical. You have a problem with that? If you just want to draw on your experience and no more, good for you. Me wants to understand the theory and connect it to practice. I am quite comfortable with heat transfer. Don't have to prove that to anyone. I have also designed plenty of electronics by now and I can assure, we to have to deal with the heat from components. You cannot just leave it.

  6. 2 weeks now, Giving some assistance to the Tortoni, she was struggling a bit. Quite enjoying growing in here. Not sure how much longer I’ll veg for, but will take it patiently for now skywalker looking to be male Get to grow these Dosixcherry cookies out, should be a treat, cheers @SkunkPharm

  7. Jip, those references helps, but the point is I will not know until I have the first prototype on my table. And that is what design is about. I now need to make the best guess I can based on the best information I can get, order the stuff and see if my expected calculations managed to reflect in practice. Design is about not having to try 50 times. It is first guess and perhaps try 2 or 3 times.

  8. I believe they are struggling due to the loadshedding. Not sure whether Dennys has closed down or if production has just been reduced? Bit of a concern, very limited supply of mushrooms and then what's going to be in low supply next?

  9. Hows this going! Locally in KZN theres virtually no mushrooms on the shelves anymore. Also read an article tuning Dennys or someone closed down so our mushroom producers seem to be struggling?

  11. Dude, just gona give you a little perspective here real quick - I have 3 different LED grow lights. I have used them all and they all got different heat dissipation. Each light got a different heat coming off the actual light and they each hav impact on the heat in my tent...... and funny enough, the kak lights heat up way more and they heat up the tent way more.... care to explain that to me mr. engineer? you don't need to worry about if I am grasping what you saying, cause what you saying has very little to nothing to do with what I am trying to explain to you. Like I said - forget about the lm/w forget about W forget about all your fancy finer details about each individual light. honestly if you do this test between 2 kak cheap diodes and 2 kak expensive diodes the results will remain the same, cause it's really not the output or the tech behind these diodes I am talking about. It's the layout of the build, the design of the light. have you heard about heatsinks for qb's - why do you think they use heatsinks? have you seen the old tech LEDs with built in fans - care to explain to me WHY those fans are there in the first place, mr.smartboi? I give you a hint - the cooler the appliance runs the better for the appliance itself that's all I am saying. the cooler the thing runs the better and there are ways to build a design that don't heat up as much sparing you on extra fans and sparing the life of your light. How you feel about that isn't gona change the fact. perhaps, get your box and your light built and gain some experience here, then maybe you'll get the picture, cause right now you being waaaayy too smart to understand basic stuff and completely missing what I am trying to say to you I don't need to have back and forth with you about something I have dealt with a long long time ago, wasnt giving the info to discuss it really, just wanted to help a fellow grower save some money and grow better weed, but yeah can't help those who don't wana be helped hey kinda perplexed at how hard it is to explain this basic info to an engineer, thought it would be like second nature to you.

  14. There are no 100% efficient devices.. we would blow to much energy into keeping supra conductive conditions if we want to run a electric system max efficient. Keep indoor growing simple, the more complicated your setup is, the more issues you have with debugging. Also, just to say it.. if you look for a perfect setup and NOT use a PAR meter ^^ you can't get to the goal anyhow. The question is, how many watts you want to use to grow. I run 480 watts on a 1.44 square meter area. Most prefer more 600 to 1000 watts on 1 square meter. The more light you put in the more light your plants have to play with.. max they can absorb is about 1000-1200 micromole PAR. Over that you need to add CO2 to get gain in production or just heat up more the environment. Problem is the more watts you run the more heat you have to remove again. Goal is to never pass 26 degrees C, over 30 your terpenes burn up and decay high speed. If you want to run things perfect during flower, keep it 20, day and night cycle. Light is important, I agree very much, but is just ONE component to have in perfect range, if you want perfect weed. I use 3000K QBs for Germ, Veg and Flower. Works... then you need fertilizers... best specific for Cannabis growing and use the fertilizer correctly. Can have the best light in the world.. if you don't feed what the plants need.. will not end well. Doesn't matter if you go Soil or Hydro... or can't make up your mind and go Coco. How you handle the plants will give the result. But.. have to learn the method and swapping means starting over again. My 5 cents: Great you look into the matter in high detail. But.. don't get lost in the forest of numbers.. the only number counting is if you are happy with your harvest. First learn the ropes and once you learned the plant, check how "perfect" you get your setup to run. Plants will tell you how they feel.. you just have to observe them and understand what they try to pass on

  15. Apogee makes a par meter, locally it would be something like this.

  16. Sounds pretty on-point to me my dude. I wish I had known how big you wanted to go before answering in your other thread My only real pointers is that more often than not it is more important to focus on environmental factors for optimal growth than it is for how much LUX your are working with. LUX is cool but most people here will use umol when deciding on light power. The standard at the moment is to achieve 700 umol at max during flowering stage. Any more than that is useless as the plant can only physically make use of 700 umol without carbon dioxide injection into the room. Some growers will find that their plants stress when running lights at maximum or that the environment gets too hot and stunts the plant. This is why I say environment is more important than lighting. Yes you need good lighting, but it isn't the only important thing when growing cannabis. Definitely right on there. UVA LEDS in my opinion are gimmicks. 3000k or 3500k full spectrum white light LEDs are all more than perfect to grow top tier bush. Interesting that you want to push 5000k during flowering. If you wanted to do that, I'd maybe suggest combining both the 3000k with the 5000k at the same time. Blue light helps keep the plant nice and short. The more red/yellow the light, the more susceptible you may be to over stretching. This will be strain specific though. The 5000k should in theory help push flowers more efficiently than the 3000k, but I still think you need some of the 3000k spectrum at the very least during pre-flower and then halfway through flower push just the 5000k. I'd personally be interested in the results. Just for reference, I have done full grows with both just the 3000k and 3500k with the same strains and in all honesty, I haven't noticed much difference in quality but the plants growing with the 3500k did stretch more during growing.

  17. I would love to call it all mine, but the reality of that is quite slim. For now owning the title is the big win. In future I would remain the biggest share holder, but to expand to the point of having a couple mil in flow is gona take me alone reeeeeaally long, but luckily there are quite a few different ways to approach this thing. If you talk to the right people and create the right kinda background for yourself and you bring the most important slice of the pie to the table (the knowledge and the numbers) then you already got your foot in the door. This "green rush" is the next big thing and I couldn't count how many big time Agriculture names wana jump on this train. by the time we hear about another BIG legal grow setup it's been months and months, perhaps even a year or more of research and paperwork was done in complete silence. these guys with the deep pockets don't like to make noise. I've had a few in depth discussions with the guy I started the Protea farm for in Hermanus, he started the farm as a retirement gift to himself. Literally bought a part of a mountain right at the top, got bulldozers and rippers dropped off up there, we ripped about 9hectares of his 100+ hectares he bought. Filled it all up with King Proteas for export to Holland. He got some rreeeeeaall deep pockets and it's about to get even deeper. He's all positive when talking cannabis lisences and what not. I keep the fire alive by talking to him about it every now and then, cause that's not what he's interested in. But let me tell you what he is interested in, money him and all the others just like him... and there are sooooo many in this beautiful farm country we live in. Afriplex themselves are very interested in cannabis medicine, they already doing some CBD stuff. Got a few conversations going at the same time, one very valuable life lesson I learned through growing - plant more than one seed
