i had that years ago with this site
http://www.1-hydroponics.co.uk/ i brought a £500 hydro kit which i might ad i had no idea how to use i didnt even no how germ a seed let alone grow in a flood n drain system lol and they sent me a extra 1000 watt ballast by mistake, kept sending the courier back asking for it lol i just said pretty much the same m8 ''no understand me no speak no english lol
as you can imagine the grow didnt go to well i gave up and sold the hydro system n extra ballast after none of me seeds germed i blame the strain yeah deffo the strain either that or the fact i just put the seeds straight from the packet into dry rockwel cubes and then in the prop lol
