outdoor hydro lettuce + nutrient

tampahydroNovember 28, 2008

My wife wants me to grow lettuce outdoors. I am looking to use either perlite, or the raft system. I read on the UF site about using only water soluble 20-20-20 plus epsom salts to grow healthy plants.

Is it true I can use simple and cheap nutrients versus the expensive hydroponics nutrients?

Anyone have experience growing lettuce down here during the Florida winter? I was wondering if I should grow on my covered south facing patio so it only receives early morning direct sunlight. If not I will place in full sun, but it can get a bit hot during mid-day.

I planned on growing grand rapids lettuce since I have the seeds, but I will change to whatever suits the Tampa winter climate the best.

I would appreciate any advice.
