Richard Jackson's Flower Power Plant Food

Hello,
I have just seen this ad on FB. Has anybody of experienced gardeners ever used it? What is your opinion? I could not find NPK of this fertiliser anywhere. For me it is greatly overpriced. What is the best fertiliser? What is the best and cheap fertiliser? Is it cheaper to compose a fertiliser yourself buying NPK separately?
Perhaps I am not right trying to find cheap fertilisers?
Thank you.

 

I just buy, high nitrogen, for early season, balanced for mid season and high potash for flowers and fruit.
Sometimes buy tomorite, its traditional.

Mostly buy Chempak.

As far as i'm concerned the rest are just hype.

 

@Black Orchid Composition of flower power
NPK FERTILISER blend with micro-nutrients 12 – 12 – 36
Plus added magnesium, sulphur, seaweed extract, wetting agent, humic acid, amino acid and fulvic acid. 475g cost £9.99 = 427.5L diluted 2.3p/L
So a high potash fertiliser with added bits.
Tomorite is NPK 4-3-8. again it has seaweed extract added 1L cost £3.50 = 225L diluted 1.5p/L
Chempak high potash NPK Ferliliser Blend 15-15-30 with micro-nutrients. 750g Cost £9.50 = 1500L diluted 0.63p/L
Probably get them cheaper if you hunt around.
Might switch to Chempak from Tomorite for next year.

 

Thank you very much!
