I dug up some info for you.

I was drunk last night when I posted, it only occurred to me today that asking a supervisor if they knew the optimum growth conditions for cannabis might not go down well. Anyway.. <br> <br>This website seemed fairly comprehensive for the conditions for hydroponic growth of cannabis. <br> <br>[www.a1b2c3.com] <br> <br>Optimum pH of solution by all accounts seems to be weakly acidic, 5.8-6.3 is the stated optimum in the website above. Obviously pH is subject to change over time and would need to be monitored daily. <br> <br>The growth stages before the vegetative stage will only require water, no nutrients. More detailed info is in the website above. As for the vegetative stage I would use Hoagland's solution, which you would have to make up with the proper chemicals, i think this may be a little hard to do at home without laboratory equipment. <br> <br>Any solution you use will need to contain the Macronutrients: Nitrogen, Phosphorus, Potassium, Sulfur, Calcium, Magnesium. <br> <br>As well as trace samples of the micronutrients: Iron, Chlorine, Manganese, Boron, Zinc, Copper, Nickel and Molybdenum. <br> <br>Its worth reading up on common mineral deficiencies in plants and how they manifest themselves in the plant. <br> <br>[www.bio.net] <br> <br>If you wanted to use Hoaglands and had access to the initial chemicals the quantities of chemicals in solution are stated in the link above. You would want the first recipe plus micronutrients. If you are interested in this recipe (and can get access to the chemicals) let me know and i'll do the calculations of the various chemicals by weight for the litre mix so you can measure them out on a scale. <br> <br>If this isn't a possibility you might be able to contact a lab supplier or something to get the fertilizer mix. <br> <br>If that is out of the question you would have to get a premixed solution or something from a gardening shop.

I'd be grateful.

Vladamir 224 November 05, 2007 09:51AM

Okay. I'll see what I can find out.

Istirith 208 November 05, 2007 09:57AM

The &quot;other stuff&quot; would be my priority.

First step is to tell NO ONE. The internet counts as EVERYONE. n/t

I'm not worried about getting caught.

Vladamir 244 November 05, 2007 01:35PM

Please tell me you didn't buy one of these...

entropissed 218 November 05, 2007 10:00AM

If I did, nutrients would have been included. :P nt

Vladamir 223 November 05, 2007 10:09AM

Seriously, there are much better places to ask this. nt

mc_no_u 233 November 05, 2007 10:40AM

You would be surprised at the amount of random knowledge on these boards. nt

Cerunnir 8222 November 05, 2007 10:42AM

No I wouldn't. Most people here are fucking retards.

mc_no_u 247 November 06, 2007 10:16AM

Sure I'll throw it over on the log board where it belongs.

Vladamir 8203 November 05, 2007 10:51AM

Even on the internet you have no life outside CF. :) nt

The Pizza Boy 247 November 06, 2007 10:17AM

Umm nitrogen is key in all stages. More later. nt
