20,000 Watt Medical Grow Op Construction

HPS light do not grow pretty plants. But, you can't sell pretty. I can grow a plant that looks perfectly healthy till the day we flush. But, it won't yield much. When I grow for weight (always), my plants are pushed so hard they suffer a bit. There are plenty of blemishes. But, the quality and the weight is there. It's the same with lighting. The induction lights may bloom a pretty plant, but pretty does not matter for shit.

This is not to take anything away from induction lighting. Only to say that people should never be interested in what "looks" healthy. They should stick to bud quality and weight.

U TELL EM CG lol

Hello stranger I got through my first grow and had damn good results.I didnt use canna based nutes didnt have the money to spend $100 for a gallon of an so I just used my compost added in fetilizer and let them grow. I dont think the dual bulb from hortilux hurt my yeild at all and hopefully in the next 6 months I can get to the west coast. Still trying to deal with a issue and hopefully it will come to rest so I can move. Take care and keep growing

Probably time for some new pics. I do have a bunch of 40" D-Bubs being flushed and looking oh so dank. These fucks are going to yield 6oz/ea.

bring on the pics cg looking forward to it

Im looking forward to it too. Like button

Excellent harvest brother!

YES!! Hey did I tell you your Hydrologic Stealth 200 you gave me is working like a champ. I don't have to pH my water every day like I used to. Seems the pH holds steadier. Plus I can now get a drink after I go to bed. I'm not stable enough to negotiate the stairs so once I'm up there I'm in for the night so now I can have water when I want it's WONDERFUL!! Thank you.

I transplanted my 4 AI moms today just in case it turns out special and I was thinking of flipping the clones tomorrow. But I have a question first. I need to switch the clones into larger containers, what size should I use and after transplanting can I just flip or should I wait for a little? Also could I flip them under the 250 metal halide or should I wait the 2 weeks for the AI's to finish then flip when the big light is ready for them? I am NOT making the same mistake of out of control canopy twice LOL.

Oh is the D-Bub different than your Bubba? How so? Could anything be danker than that Bubba you grow? One puff of that and within a few minutes my eyes cross and suddenly it's the next morning LOL! But the most fascinating thing about it is that I only have to use it once every 4 days and it potentiates the morphine for that long. I am just amazed how long it keeps working for pain control long after the high has worn off. It's incredible stuff, thank you so much for it.

Nice. I just finished curing my latest sour D harvest. I grew this round in ten gallon containers, I yielded between 8-10 oz each...

There's just no substitute for big containers, is there. We've moved from rockwool blocks to rockwool/perlite in 2 gal containers, to rockwool/perlite in 3 gal containers. The increased medium mass provides our blooming plants with more access to mag. It also eneables us to mix in more perlite for increases air flow and growing power. While we could grow up to 6oz plants in these pots, 3-4oz plants in greater numbers really make a nice efficient canopy. But, not matter what I do Commercial J does it better. The only solace I have is that he's SO anal he needs every crop to be perfect. This results in less crops/year. I'm a little less picky and will tolerate some imperfections in the live plants so long as finished quality is not affected. This, and the perpetual harvest, keeps our bloom room full all the time...the KEY to growing a perpetual.

Very true. I'm currently rocking 5,7, and 10 gallon containers depending on which area they're being grown. I'd tend to agree that 4oz plants make the most efficient use of space/light, but I'm always tweaking things to see what works best. On a downer note, I've finally contracted the dreaded PM (managed many years PM free) and I know that scurge came from an infected cut. Never again...

Well this is good information and makes sense. You have got to be kidding! YOU LESS PICKY!! All the mmj you have given me is spectacularly good looking. How could anything look, or even smell, better than your Pre-98? From the dispensary I visited to now my own AI's your buds are really good looking and for potency wow. I just tried a sample of my AI and it was very disappointing compared to yours. No pain relief. I'm hoping it is just to early and will get that effect if I wait but we'll see. I can't imagine how fabulous Commercial J's stuff must be if you sing it's praises because your stuff is incredible.

i read back to where my last post was, do u mean LED lights or the dual mh/hps hortilux lights that grow pretty.

I have followed this post on and off for a while but have never posted. I was just looking at your nute rack and it is everything I use, and personally I love them. I'm not trying to tell you what to do or anything, as I see here you seem to have it figured out pretty nicely . But in my opinion and also the CEO's of Advanced Nutrients opinion, use Roots Excelerator by House and Garden. There is a video on youtube of the CEO talking all about Roots Excelerator.

i think CG uses roots from yellow bottle. not sure if he still does tho

Hey CG got a question, with your current setup being drain to waist! How long can you go between waterings?
And do you go feed, feed, water or some other feeding plan?

Without places and people like this to share the experiance, growing would still be a very VERY lonely endeaver.

pfffff ... ain't that the truth

We'll build the system ourselves...it's way too easy not to. The only real modification from the original Under Current is that we'll be using smaller and flexable hose between the buckets. I need the ability to move the buckets around a bit...pet peeve of mine. I believe that the air stone with large enough pump adds more than enough oxygen to the roots. My current DWC test buckets just have this and the growth is nothing short of explosive. The main reason for connecting 10 buckets to a common res is to add some nutrient solution buffer capacity and to make solution changes and adjustments easily done at a common location for every 10 buckets. Also, if an air stone should fail, the circulating water would provide areated water to the plant regardless. I'm not even sure that I'll go with the second res hooked up to the float valve to automatically add water. First off, it will take up precious room. Also, I believe it is important to force ourselves to have to go and check everything everyday. I don't mind having to be at the grow everyday...I just don't want Helper D to have to spend 3+ hrs/day just draining buckets, mixing solution, and watering. Not to mention transplanting and soil disposal time. I also have to admit that over the years, my most prolific grows have been hydroponic.I started this grow soiless because I wanted the reliability while we sorted out the rest of the room's systems. Now that we're there. I'm ready to crank it up a notch. My hat's off to the Under Current designers for designing a DWC system that allows movable buckets (with our modification), a centralized solution tank, and doesn't rely 100% on each air stone functioning perfectly.

The changover will take place over the next few months. We have plants in all stages of growth right now.

soilless is basically hydro dont forget that cleaning all the rdwc buckets every grow is just as much work if not more then using soiless plus when people are counting on getting meds from you its always good to use a system that will make it through power outage just in case i have have grow both ways and rdwc will def beat every other system out but i like having a buffer just incase

Sorry for the delayed response. We've been busy updating the A/C and getting the CO2 thing going.

I like to feed with every watering, but I'm continually reducing my nute concentration. We finally picked up a Blue Lab TDS/PH monnitor. We also started using just EC, rather than PPM. There are 2 formulas for going from EC to PPM, and the results are around 400ppm different. Fuck that. For a while I was feeding at anywhere between 1.5 EC and 2.0 EC. This is too hot. I then went to just 1.5 EC. This, too is too hot. Now I feed between 1.0 EC and 1.5 EC. Basically 1.5 EC during peak bloom time (week 2-5), and 1.0 EC during Veg, transition, and late bloom.

We are now using rockwool croutons/perlite mix at 2:1. 2 Gallon pot were big enough for 2oz plants. But, with dialed in nutes and perfect pruning, some plants are getting closer to 4oz. Therefore, we've stepped up to 3 gal pots. The larger diameter containers, combined with aggresive upper fan leaf pruning in veg, are creating some amazing multi branch plants. Of course, this settup is very similar to Commercial J's settup. He uses 1.75 gallon pot, though.

We're updating the A/C to 21 seer inverter ductless mini splits. These were the most energy efficient I could find. Yesterday we added booster fans to the air inlets on the ducts feeding cooling air to the lights. The cooler the lights are, the easier the job is for the A/C's. This is the spring overhaul I've been planning for a while. I knew this summer would strain our current A/C's. We also wanted to seal up and start adding CO2. While the D-Bub and the Tahoe grow great w/o added CO2, the Pre-98 actually doubles the yield with CO2. After it tested in at 21% THC, our Pre-98 went into mega-demand mode with our patients. We just couldn't produce enough w/o CO2 enrichment. So, next Saturday we make the change from fresh air cooled to sealed and enriched. Most of my past grows have been CO2 enriched, and I'm looking forward to the explosive growth. I am glad we started out w/o CO2. This allowed us to 100% dial in the 3 strains. Now we're ready to see what these girls can do.

Bump your temps up a few degrees with the added co2 (as I'm sure you know), it helps as long as you don't hit the point of getting "blowout" in your buds...
