That's definitely a better way than LEDs. You're getting certain radiations that induce flowering. That's why LEDs will veg well, but by themselves flower weak.
@@kiddynamite3931 yeah Man led make nice buds but not as large and yeah cmh is the way to go with spread and quality light but led is so cheap that's what I like the mixture I've been using the migro uvb light and it dose work abit I noticed bigger yield but I changed bulbs to more red so it's probably that but have noticed a touch stronger, usually just put it on for 1 and a half hours but yeah man I use the leds to fill in spaces that need light so i don't need another cmh as overkill, I did use the 600w cmh replacement bulb in hps but still would rather 2x cmh.
@@robertmiller6822 I'm glad you mentioned something, as you have worked with both LED, and HPS. I take my yield into account with my cost. I'm not a heavy user, so 1 grow a year has me set with meds.

Its probably because you are not used to the low or no radiant heat from LEDs which means your leaf temperature is cooler if you keep your ambient temperature the same. Most find they need to raise the ambient temperature to make up for the loss of radiant heat from the light. You save on electricity hands down.
You should put grow tent in the title so people with larger gardens know what they are clicking on.. Needless to say that has nothing to do with the quality and detail of your video bro! Great job 💯
When you're adding CO2 either through a canister or mushroom bag, you're introducing more CO2 into the growing environment than you would with a normal in-take fan from outside. Plus CO2 is a heavier gas meaning in general it'll concentrate lower in the tent, away from the extraction system at the top of the tent. So will you extract some CO2 with an extraction system? Yes, but nowhere near the amount of CO2 you're adding. Plus if you're worried about extracting it all away you can always turn down your extraction system to a lower setting.
My cheap co2 set up. I have a 4x4 in a small room about 10ft long and 7ft wide. With a fish tank co2 generator. filled with 400g or bicarbonate of soda and 400g of citric acid...both cleaning product quality. + 600ml of water. running at 800-1200 ppm as the grow progresses (waveform from of 150ppm). each refill cost about $2.40 and last 4 days 24/7 as I run 24 hour light. . But do open up for half an hour and refresh the room each night. Tank and controller outside the tent with tube going in and placed above the canopy. Two vents open on the tent like scoopes and it all just circulates around the small room and tent. I get longer more economical waveforms at 82F - 85f which is higher than my old style of 78f. I only run the system for about 5 weeks in the centre of a 10 week auto's grow. so the last 2 weeks of veg and first 3 of flower. as I want lower temps at the end without reducing the light, ( i.e open the window.) as the lower temps preserve the terpenes, but in summer I still have to drop to 3/4 power to achieve the heat reduction. Also high humidity, increases the wave form as it hangs in the air longer. so 70% is fine at those higher temps in that stage of the grow, Hence why I stop in later flower, as I want lower humidity of 50- 60%. app controlled humidifier in the tent. but dehumidifier outside tent if required. I run my 6 inch AC infinity at levels 4 and 5. triggering 6 occasionally. which keeps the system stable 4L Tank was about $120 with solenoid and Digital CO2 Carbon Dioxide IAQ Monitor Controller. was $140. has a light out cut off. My yield has gone from 14-17 per run to 21-23oz in four 16 L pots Coco perlite... under lumatek 600w pro Using advanced nutrients PH perfect range.
I'm reusing LEDs from a stip light usaly found in public toilets or schools but specs from online say they can be used as they have the full spectrum of sunlight but no dimmer switch where could I get one
My best way. Three 1 liters or two 1 liters and a small soda bottles clear on the last one. Get air tubing line, about 2½feet. First bottle 1 table spoon yeast, instant isn't the best, you'll want a slow expanding one. I just use the best choice jar. Get warm warm water fill the first liter half way with warm water, the second 60 to 65% up. The drill one hole in 1 cap then drill two holes in thelast two. cap. Put one tube in the 1hole cap on first bottle filled and with 1 to 2 table spoons of yeast. Mix shake well before you drill the hole actually lol. Then put the air tube all the way down to the bottom, then get the tube and connect to the first hole and put it about 3 to 4 inches under water, second tube connect that and put about 2 to 3 inches in the bottle just make sure it's above the water, that tube will be where the qfiltered gas comes out and how you can see that it's making co2, the last bottle, I like a small one for this. Connect the tub and have about 2 to 3 inches under water. Another tube partial like the previous, then connect to the second bottle tube suspending again. But that will leave you to lay the tube or split it and lay it near whatever plants needs it the most.
It’s best to start these off on a low setting, around 120cm away from young plants, and gradually reduce the distance as the plant matures. We’d recommend a distance of 50-60 cm from canopy when they are fully flowering.
Yes, all Bar LED's have slightly differing outputs, but this is our general guidance. This video is about the Exolux Sirius but much of what is discussed can be applied to other 660W Bar LED Grow Lights. czcams.com/video/12-9s_Bc-Yc/video.html So you might find this helpful.
Its my first grow in 10+ years i just bought a fc3000 in a 3x3 tent. Any height advice for veg and flower and at what power setting? Any advice would be appreciated thanks
For a 300W LED start roughly 1.2m - 1.5m above your plants. If you've just transplanted or potted up about 50% power should be used initially. Gradually increase the intensity and lower the fixture to 1.2m above the canopy throughout veg. Then for flowering lower the fixture to roughly 70cm - 80cm above the plant canopy. This is a rough guide based off other 300W LED's we sell, can't speak specifically for the FC3000 as we don't stock it, so keep an eye and adjust as you see fit.
@@growell I have the 660w pro coming very soon and I have a 1.2 possibly upgrading to 1.5 but for now what height amd power do I use for veg and flower etc? I hope you get to see this soon and shed any light it will be much appreciated 🙏
LED costs much less electricity, but keep in mind sometimes you would actually save money by running HPS. 1) Initial costs of HPS are usually cheaper than a LED. 2) Some LED's are bad quality and they don't last too long, then if it starts malfunctioning you'd need to buy another expensive light or components. 3) HPS produces more heat which may be a good thing in winter. With LED you might need to run a heater. 4) HPS produces UV & IR wavelengths naturally, which helps with increasing potency, flavor and aroma. And it helps against mold and mildew. But with LED you'd need a supplemental UV light. Some LED's have IR diodes but some of them don't. And you'd need more protection against pests with LED. Everything has pros and cons.
For a tent of that size you'd be fine with just one CO2 bag. You can get them from us here: www.growell.co.uk/fans-filters-environment/co2/the-exhale-365-self-activated-co2-bag.html
If you've got a quite a large grow and a safe space to use them, propane CO2 burners like HotBox and Pro-Leaf CO2 generators are an excellent producer of CO2 if you're growing under LED's. But it would have to be a very large space, starting around the 8m x 8m mark. Otherwise you'd need an additional controller.
There are hot spots if your ballast is attached to the light. If the ballast is removable move that sucker outta your tent..... Also for new growers know there is no such thing as a climate CONTROLLED tent. The tent is just as hot or cold as outside the tent... The tents only gonna get hotter. If you have a mini split you can put it in the tent but know your fans will extract that air but if the extracted air is going into the grow room (Which it really shouldn't but im not writing an article here) then it will make the ambient temperature cooler.
If you've got the available space outside your tent this is definitely a good call regardless of what lighting system your using, as it makes working in the grow space so much easier.
You don't want pets in the same room as your plants, they carry diseases that can make your grow a living hell. Just spending a little time in your lung room will provide plenty of CO2 for your plants. And who doesn't check on their girls on a daily basis?
I have two kids, a wife and some dogs. My very expensive co2 meter shows my grow tents (5x5) is 600ppm on average. Lesser used rooms are around 350-400. A top shelf led can utilize significantly more usable light and for that a co2 source would be useful. Not the mushroom bags or most diy options as they only raise the ppm minimally. I found the mushroom bags to raise the ppm about 50-100ppm depending on what phase of growth in the bag. The citric acid/baking soda in two 5 gallon buckets raised the co2 2-300 and is scent less. The issue I find is the requirement for weekly recharging. DIY sugar and yeast in two 5 gallon buckets raise the ppm of a 5x5 to over 1000ppm + . The difference is 350-600ppm of co2 and only requires more sugar every 2-3 weeks. The downside is you’re making hooch and thus there will be a scent. Does anyone really need more co2? Not really. Would your plants grow faster, stronger and produce more fruits with more co2 and more usable light? 100% yes The issue some folks overlook is in many cases their LEDs simply do not put out enough “usable” light to take advantage of more co2
Just dim it down to 50% and lower it down to 12'' distance. That should do it. Where is the efficiency in putting 700 W in a 4'x4' ?

If you grow in a tent and exhaust it with fans, then adding CO2 is pretty much worthless. youd think they would know that

How many of these will i need to cover a 2.4x2.4 meter tent?
For a tent that size we would recommend 4 x Exolux Pro Sirius LED's. Most Bar LED's in the 600W - 630W range cover a 1.2 x 1.2m area.
