Need input and help on set up

Hello,

I'm growing legally as a caregiver and I ran into a problem and need some help but allow me to explain everything first.
So, I have a building with a main floor and then a basement level. Both floors are 28W x 23L , the upper floor is a 10 foot ceiling while the basement is 7-8 feet.

My original plan was going to have a 24 plant cycle. 24 plants upstairs for bloom, 24 plants downstairs for veg, and 24 clones downstairs as well. One light per plant, the Nanolux 630w cmh is the light I was planning on using. Each plant would have a 3x3 PVC built trellis net around it(scrog), with another 2 feet of space between the plants on all sides so I have plenty of walking room to tend to the plants.

I was also going to have 2 5 Ton Ac units installed as well incase one was to fail, the other would kick on so the plants are not affected. This was my plan until the electrician came to the property.

So, basically he said I don't have enough power to do everything as I wanted, and would need at least 800-1000 amps. The building I will be growing in has 100 amps, but he said he can use the other 200 amps from the house. (barn has 100 amps, house has 200 amps) He said the original 100 amps in the barn would be enough for the downstairs but he suggested to use LED lights for veg since they use less amps.

Then for the upstairs, he said he'd run the power from the pole box for the house which has 200 amps. He said I can use the 24 lights like I planned for flower, but no to the 5 ton ac units. He suggested to divide the upper floor in half so it has two rooms. One room would have the lights on for 12 hours, while the other has them off, and it'll rotate like that. Then for the AC, he suggested a split zone ac unit in the middle of the two rooms which would pump ac in the room that has the lights on, and pump heat in the room thats off, and rotate like that as well.

But tomorrow I will be calling the company that powers my area tomorrow first thing in the morning to see how soon they can add power because the electrician said it can take months to get someone out here and add the power I need.

So now that you all know the backstory. What LED lights do you guys recommend? Also, what are your thoughts on the split zone ac? Any feedback would be awesome, thanks !
 
Consider putting a 15K btu window unit upstairs & downstairs. Also you don't need 1 light per plant. 630 watts can support 22 ounces of bud, So that's like 5-7 large plants per light. Also make sure you get the kelvin temps right on your lights, for veg 4 k and for flower 3k . If theres an extra window in both zones get a box fan for the window and pull fresh air in every morning very early for about an hour. Atmospheric co2 is highest at these times and will greatly increase your yield.
 
800-1000amp service is not going to be cheap. It also seems very high. The lights you listed and the AC is all under 500 amps.

Don't argue with the pros your paying them for a reason but a second or third opinion is never a bad idea. When you start trying to go that big you're entering the commercial world and it's going to cost money

That's a large investment, and a whopper of an electrical bill every month. Will you have access to enough water for an operation that size?

I'd have an HVAC specialist take a look at your requirements. If you are looking to move heat between the two flowering rooms, can you do this with fans? Can you lower the heat input to the active flowering room by moving the ballasts to the inactive room, or an electrical service room vented to the outside? Would geothermal heat pumps be a better solution?

Thanks for the input!! but yes there are windows, I was planning on closing them because I thought the rooms are supposed to be enclosed from other light? or would the window unit block off the sunlight?
Also, I would put more plants under each light, but I'm building a pvc trellis net around each plant so that takes up 9 sq ft (3x3) for each plant so unfortunately I don't think I can fit more plants under each light. Or I may be mistaken, but I am open to all advice/suggestions! Thanks!
 
I'd look into Fluence lights.

Thanks for the welcome! But yes I know, my father and I are putting a lot of money into this but we like to do everything right which is why I'm stressing over this problem.
And yes, I have a couple specialists coming by this week to give their input on the AC as well. These are all great questions and Ill make sure to ask them! Thanks!!
 
I will say this if you don't understand how to care for plants (esp. cannabis) then you should study that before you spend big on beans. Understanding all of the nutrients and the ceiling levels of each are crucial to success. Cannabis stunts very easily and once the leave tissue is damaged theres little that can be done. Many new breeders jump in the fire without having a proper grip on fundamentals. Avoid that.

yes you're absolutely right. Just wanted some opinions from everyone else that grows, never hurts to ask around (-:

I totally agree with you, I've been preparing for this for months now, since November last year I have been on these forums, as well as grass city all day everyday, as well as researching online and meeting growers and learning from them. It definitely will not be easy but Ive been trying my hardest to learn more and more everyday. The amount of information I've retained the past few months is insane. Also I have family that has been growing for a while now too so I always have them in my back pocket for help. Thanks for the reply and advice!!
 
My Dad taught me soil 30 yrs ago. There are magic #s when it comes to nutrients. We had a mj grow bible on the coffee table and a stack of high times on the floor. The only way to get beans then was to order from the classifieds in those mags or seed crop or know someone. But back then you could be 110 guys knew what they were doing. Now... Even the nutrient mfgs. are getting it wrong. Look around. People having problems. They are following directions to the letter and spending big. They don't know right from wrong. And they are failing because the knowledge is flawed from the start. Look at peoples plants. That alone will tell you if they know what they are doing.

thanks for the advice, i honestly appreciate it. And oh yes they've all shown me pictures of their gardens. But time will tell for myself, I am sure you'll see me posting more on here as time goes by! Ive researched countless hours a day literally everyday, and continuing to do so. Can never learn too much! Thanks again!
 
I suggest starting a test grow ASAP using the methods you plan on implementing. Use the same strains, lights, medium, and nutrients. Space the plants as per your plan. This will reveal any problems you may encounter, and give you a chance to resolve them before it affects your entire operation.

It may be an idea to put this room (or two) in the buildings you will be using. It will be handy to have a place to experiment with new procedures, or produce your own seed.
 
This is the best advice your going to get right here.

Good idea. Ill get started on that with like 4 lights and plants. Thank you all!!
