4-18-32 nutrient - is it available in the UK?

[Simon Carr]

Hi, I am about to embark on my first forray into Hydroponics. I will be starting simple to begin with and growing just lettuce and herbs.

I have been looking for the best Nutrient for the job and to be honest unless your growing cannabis, it is seems to be difficult to find any information. I did however find this video on Youtube https://www.youtube.com/watch?v=TQzgMve9hoA he demonstrates clearly that the nutrient I need is 4-18-32, but for the life of me I can only find US suppliers.

Can anyone help or suggest an alternative and if possible pictures or video to backup the advice.

Many thanks

[Bob]

How can DC even contemplate adding "11 million" to our workforce when over 20 million Americans are seeking work ? WE do not need to deport illegals. Quit hiring illegals, quit housing illegals, quit feeding illegals, quit schooling illegal kids and quit attending to illegal medical needs. THEY WILL SELF DEPORT !!

4-18-32

that seems to be way off the mark for lettuce.

the the amount of P is way over the top and the K should be close to the N.

lettuce is not a fruiting crop and has no flowers that you want to encourage.

140ppm N 30ppm P 120ppm K and 35ppm Mg i would suggest as a starting point.

and i know what you mean with the nutrients available.

however i will tell you that the 4-18-32 nutrient will work, just you will need to dump the nutrient more often. 

i design nutrient for large hydroponic farms so when i see something that is way off the mark for lettuce i have to say something.

good luck with the endeavor :)

I appreciate the feed back, but have you seen the video. The proof seems to be in the pudding. I do understand that other additives are also needed. In the end I found the closes I could find to what he eventually ends up with. I got #4 15-15-30 from ebay. http://www.ebay.co.uk/itm/380256308975?_trksid=p2057872.m2749.l2648&ssPageName=STRK%3AMEBIDX%3AIT

well i checked out the video,

they are sick looking lettuce, not a fair example really. different types of lettuce. the butters the ones he shows as the proof baby cos as what is wrong. they do not look well really.

leaves should be crisp and standing up more. the roots look like you would expect with 18P on the butters. 

found this article on ghost gully. ghost has been using my formulation for over 10 years now.

link intelligent farm management ghost gully produce

and understand that it will grow, i am not saying that it will not. just that it would cost you a fortune to use on a commercial size farm. as it would fall out of balance quickly.
