NFT Hydroponics System Update and Harvest + Other Hydroponics in UK

The NFT hydroponics system has done great over the Winter and it's harvest time for the Chinese cabbage / Napa cabbage - they are HUGE and some have bolted as the greenhouse gets might warm on a sunny day.
The greenhouse s unheated but it's double glazed - basically a conservatory attached to a shed so it holds heat very well.
This video also has an update on the Kratky method of hydroponics (where I'm growing lettuce and onions) and the vertical growing towers which have more than a few lettuce in them.

The propagator in the video is a Geopod (Large size) with 100w heater in the base and 2 x Sunblaster lights.
Nutrients used in the hyrdoponics systems are from Intense Nutrients and are Hydro Grow part A + B.
I bought the nutrients and test stick from North East Hydroponics http://www.northeasthydro.com

Next project is to have the NFT system planted up with micro tomato plants since the weather will get warmer soon and I would like a good long growing season for them - they produce heavy crops of small tasty tomatoes.
I also have a nation of other types of tomato, chilli and pepper seeds planted so the greenhouse will be a forest again this year.
Thanks for watching - see you next time.
