10 x 600w HPS - Expected Yield?

Hello,

Long time reader, first time poster here.

I am aware that there is no straight forward answer to this and any estimates are purely that, just estimates.

Below are images of the set-up (digital images, not photographs - For security reasons). Imagine the lights on the ceiling are 600w "Cool Tube" HPS lights with red spectrum bulbs.

The walls are lined with Mylar and the plants are evenly spaced. There is 1 x 600w HPS light, with red spectrum bulbs for every 4.7 plants - Making 47 plants in total.

Other details that may be pertinent.

Strain: Dr Krispin - The Incredible Bulk
Pots: 15 Litre - drain holes in the bottom with 2 inches of coarse gravel
Grow Medium: Canna Coco Soil? (I think)
Ambient Temp: 22ºC // 74ºF
Ambient Humidity: 33% - 35% humidity - Varies hour to hour, not sure why...
Lighting: 10 x 600w "Cool Tube" HPS - Red spectrum Bulbs
Veg Time: 5 Weeks (35 days)
Height at time of 12/12: 36" (2.5 Feet)
Nutes etc: Canna Boost / A/B


Now, This is the first grow I have put money into and been involved in, however, we have a gentleman working with me/us that has done 50+ over the past 5 years (mostly smaller, 12 - 20 plants). He is stating that he can, with quite a degree of certainty yield over 5oz per plant - Giving a total of: 235 Oz // 6.5 kg.

Everything I have ever read says that people very, very, very rarely drop anything over 2oz per plant... But 1g per W of light is more than achievable (which, again, doesn't seem to make sense?)

As we have 6000w - which should be 6 kg (acceptable dried yield for us)... but the 2 oz per plant figure only equals 94oz // 2.6 kg.


So, long story short - Is 5 ounces realistic considering this guy is a relatively experienced grower - with our set-up.

Spank you muchly in advance.

-Naaa

I run 600's (on a smaller scale) and avg around 1lb per 600 watt light. give or take a little depending on strain.

1g per watt is only if you get everything spot on and isn't really realistic especially just starting up.

So that estimate puts it at 3.41oz per plant - Which would be almost acceptable financially -

I don't understand the entire situation online vs real life... As, everybody locally (with no perceived bullshit) are claiming 4oz absolute minimum per plant - and that's with 4 plants under a 400w etc etc. Then online, nobody comes close to those figures.

Also - I note I am in the UK - Maybe that makes a difference .

I dunno about that, is there a difference in wattage across the pond? Lol

About a pound times ten.


Its hard to say. To many variables for an accurate estimate. Also, gram per watt doesn't mean anything. How long you veg does. If I get .5 in half the time you get 1 gpw its the same.

If you veg for 4 weeks - and I veg for 8 weeks... You still won't complete the cycle in half the time of me though? Or so I thought...

Anyway - Seems like 1lb (450g) per 600w seems viable... So 4.5kg ( Hypothetical value circa £25,000 in my locale )

Bumping for further answers.

50+ grows in 5 years? I'd do your research and not put all your eggs in your homies basket... With that being said..

Where did you get your genetics? Is this a fresh air or co2 grow?.. Can you raise your temps a few degrees? You are biting off ALOT with 10 lights for a first run. 5 ounces average in 15 liter pots is achievable but not likely . I would say 3 ounces a piece would be a more obtainable goal. But if your plants get huge as fuck you may get your 5 average. It sounds to me like home boy isn't as experienced as you think or else he would be able to lay out the logic of how things work. 1 gram + per watt is only achievable in perfect conditions with an experienced farmer and proper genetics. That is a good goal to have, but it is not likely your going to get those numbers. I'm just trying to be realistic . There is a learning curve with cannabis

There are so many variables that your not thinking about... Pot size, medium, growing environment, genetics .. I average 9 ounces a piece out of a 7 gallon container with blue dream.. My og in the same pot size only averages 6 ounces . But I'm growing in pots twice the size as yours .

If you havent bought shitty and headache inducing cooltubes already go with Gavita 6/750's and save yourself some cash and stress now by not upgrading later. Trust me on this. Your going to need air conditioning too though. Your weights will be up and above single ended 600's rite out the gate if you dont fuck them up too much. Especially junk cool tubes. They are the gutter of air coolable reflectors and throw out a terrible light spread and footprint. Its inherent in the design. Peronally i think cooltubes are an abomination and should be banned. Lol. Hope your grow goes well and Good luck candleaBRA!!!

I would say 100 pounds.... maybe a 1,000.

But If I were you I would run vertical 1k bare bulbs, AC, co2 and Trees. 2lbs a light. so 12 lbs a harvest.

multiply that by...

the fact that you don,t know what your doing.. X .90

The fact that you were even considering using a cool tube X .70

You have spent the time to make a digital drawing of said room X .60

So you end up with about 7 lbs.

This is an interesting post, I personally have never grown although i have been looking to venture that way. I was looking at investing about 5k USD in a few months. Although i cannot find a good location, I live with my parents as of right now, as i am also working and going to school at the same time. but i'm always sitting in class convincing myself that the future at least on the eastern seaboard for the next few years is still to grow and make quite a nice amount of cash to then further help with paying for my education. How can you discretely have a op? From what i have read its dangerous to pull 5KW from your power because it can be very suspicious with the 18/6 and 12/12 cycles, as the power companies can see that. Is it better to go solar and is it worth the investment. How about location, what is the best location. your own home on some plot of land? I'm just trying to find the best and least risk taking road with highest profit per grow.

150oz....and...5 tons a/c

I tell anyone that approaches cannabis growing with that mindset to not even bother. It almost never turns out the way you envisioned . And you kind of missed the boat. The future is poppy cultivation. The cartels in mexico are now starting up with it. Farmers are razing thousands of acres of fertile land used for marijuana crops for generations and planting opium poppies intstead. America is inundated with opiate drugs and will be even more.in the future as legalization continues to play out.

@MrJAB97 I am just an old fella offering my opinion for free. I am not trying to be condescending. I respect the honesty of your post and respect you as a person.
So for what it's worth here we go.
For every exciting success story you hear about getting rich growing cannabis commercially there is an equally depressing story of getting busted and fending off booty bandits in prison.

I suppose my focus would be on the profit to risk ratio.

Let us say you are hypothetically 18-19 year old living with your folks getting an education but you want to make something of yourself.
Option number one: Jump straight into a commercial scale operation dumping 5k on something you yourself admit to having little experience with. Such as the logistics of not owning/renting a property to operate from. Buying, transporting and setting up equipment safely. Harvesting and distributing your product without exposing yourself to the various risks that this entails. Relying on others to help and trusting them not to point to you as the kingpin if it all goes south. Pretty daunting stuff. Ignore the pot of gold at the end of the rainbow and have a think on every practical detail. Is this option impossible? Nope. Does it have an incredibly steep and dangerous learning curve? Yep. Profit is a maybe, risk is a definate.Looking after a large grow is a lot of work.

Now let's have a look at option number two. You play it cool and calculated. Finish your education get a job you can tolerate. Use some of the 5k to rent yourself an apartment or even better a house.Please do not grow in your parents house.America has some crazy property seizure laws. I lived on the Eastern seaboard when I was younger and started my first grow in the woods. Get yourself a modest grow set up and learn how to grow from start to finish on a smaller personal scale. Learn as much as you can from forums like this one. Profit will be small in money but rich in experience. The best thing is if you still want to proceed with Option One you can but with your eyes wide open and confident in your abilities.

If you decide to go with option one right now. If you don't lift weights, start. Learn Krav Maga if you can.
Never post an accurate description of your large grow op on any websites. When you send stuff out on the internet you can not take it back. Who do you think the police or thieves would be more interested in? Little John with his 4-5 plants or Big John with his thousands of dollars of weed and grow equipment. Police can and will take your laptop, phone whatever. When you try to say it was my first time in court and the states enters 3 years of grow journals from your laptop as evidence of your continuing criminal enterprise it will suck.
Instead of having one massive basket with all your eggs in it that will look impressive on the evening news as the cops are loading all into vans along with you and your buddies. Spread it out, lots of small grows here and there. No heavy time for small grows no leverage to turn your partners against you. No heavy financial loss if one get popped. It is about the profit to risk ratio.

I wish you the best of luck in whatever you choose to do with your life.

Cheers,
Will

You need to do a lot more research. You haven't even scrapped the surface of what it takes to be successful in this type of business.

You mention no cooling solution except cool tubes. No mention of training. A 600watt bulb will only penetrate about 18". Anything under that will be trash. No mention of humidity control. You doing the whole cycle in this room? If so hps vegging will produce very stretchy plants. How about air circulation? Smell control? Storage room for nuts and supplies? Drying and trimming area? Water quality control? Prep area to mix up drums of food?

IMHO that guy with 50+ grows is blowing smoke up your ass. Start small and go from there. You may end up finding out this is way more work than you were expecting.

"Large scale" and $5k?

Lololololololololo.

Let's put it this way, we got a commercial building and set up 70k watts of sealed flower rooms. Hydro.

We spent $160k before we ever harvested a thing. Yeah, we are doing quite well now but it's not like I'm rolling around town in a Gallardo. Don't let the numbers fool you. It takes A LOT of money to grow weed large scale. Our outlay is 18k a month.

Study in school and get a real job. Your too young and broke and inexperienced to get into the legal (or illegal) weed game.

Harsh yes, but that is the cold hard truth.

Bout a pound

You should use the chandeliers from the pics instead of cool tubes, theyre more classy.

^ it's true. Remove the center bulb from the chandelier and duct tape a pot in there. Killing it vertical!!
