Thanks @codster25, No, that will not be possible, but that isn't really the problem. I have worked that out, with green manure (cover crop) and mulching after. The issue here is a calculation for compost tea ingredients per plant... So one knows how much to order. I have found compost tea...

Yes, it is a bit like having kids... Everybody wants the best for their own and being stubborn to other people's education tips is normal! :D

Thanks ganga gurl! We're trying to help the soil to do, what it naturally knows what to do. If we were to use pots, we could definitely pre-mix. With 12000 plants, you don't really want to be spending money on pots. Mixing in nutes into soil would require tilling, but -sorry, don't mean to...

Hi, I'm to embark on a medical grow op. For our first season we will have 12000 auto plants growing on 1 ha. Since I'm used to a bit less plants in an indoor environment, I'm searching everywhere for a "shopping list". We're looking to start off the soil with green manure and would like to...

Yep! That's the plan. ;) Sadly, I'm only getting the soil testing done this week and I haven't been on site yet. Porbably we will have to get a quick cover crop in, just to be on the safe side.

Forgot to ask: How did they deal with night time temp changes? Would you please be so kind to take a look at the chart below and tell me, if it coincides with your experience? If you wonder for a second... I'm in the southern hemisphere, so our summer is your winter.

Thanks, Doc! ;) Yeah, it's a bit of an issue... We will be located in Lesotho, which is the exact opposite of Wakanda.

Hi, to all GMP compliant, licensed growers out there: Are there any firms that help with obtaining GACP/GMP compliance, that you would recommend? Not expecting many answers on this one... :lol:

Thanks guys. Yes, I just finished talking to a seed wholesaler. It's going to be rather on the large side.:weed:

Thanks!!!

Thanks, that makes me feel much better. Any great strains you would recommend? Was it mostly indica?

Hi, I'm looking to grow outdoor at 1600m/5249ft in a tropical highland climate. Anybody got recommendations on high altitude autoflowering strains? There won't be that many, but please let it rain recommendations!

Duh! I'm not spending >50k for grow lights that would only cover a bonsai.:lol: But the output is crazy. They're used for testing UV exposure on materials, ageing and other shit. It goes up to 2,5x 100 CRI so one can speed up processes. While it most definitely brings out terpines and in...

Always happy about people trying to sincerely help. It is the intention that counts. Yes, no AC will be used. I was just wondering how one were to calculate it, if one were to use an AC. It is fairly easy to find calculations on heating requirements, but sadly none on cooling requirements.

Thanks, for the reply. I'm planning a geothermal cooling system for the greenhouse. https://www.rollitup.org/t/geothermal-climate-battery-and-fan-sizing.994869/ Humidity outside is between 30-40% max, which I'm not too worried about, but evaporative coolers are def a no go! It is a closed...

Hi everybody, can anybody help me with how to calculate cooling requirements for a greenhouse?

and these two...

Hi there, I need some help with correct fan sizing for a 30m x 8.5m x 3.35m(h)/ 100' x 28' x 11'(h). The added challenges are having to push or pull everything geothermal tubing, whilst not being so loud/power hungry. There is a lot to plan and not enough info readily available on the topic. I...

That seems to sum it up... Although I was hoping for a different answer, something that would make sense in a commercial setting, where there are no plant limits. Because we have no limits with the licenses here in Africa.

Generally any illegal operation is built on producing a good enough product for as low as possible. That wasn't any different in the States, when it was illegal. With the exeption of some amazing homegrown. But not bashing or being passive aggressive... In the 90s and early 2000s I had way worse...
