Fertilizing Radishes

nallred91December 20, 2011

I'm going to attempt to grow some radishes in 100% turface in some of the spare space I have under the lights for my succulents.

Does anyone have any advice for how much I should fertilize? I have dyna-gro FP and MG c&s fertilizer. I'm thinking the FP has too much nitrogen and that the c&s fertilizer would probably be my best bet? I've spent a few hours tonight trying to find answers but I've finally given in and decided to ask on here.

Thanks in advanced =)

I never fertilize radishes.

In a garden that makes sense. but since i'll be using an inorganic medium with absolutely no nutrients i'll need to add some. I guess then it's safe to assume I could fertilize them minimally and they'll be ok?

Google 'grow hydroponic radishes' for lots of info. The link below seems quite helpful on the fertilizer issue. Recommends low-N and high K like 15-15-20 diluted.

Also check out the Hydroponics forum here for more discussions.

Oh that's good thinking. Based on that article it looks like I should use the C&S fertilizer. I guess now I just need to decide what concentration to use. Since i'll be fertilizing with every watering I'd assume it should be pretty dilute. Guess more research into hyrdoponics is in order!
