They actually sent me 12ml units, no complaints, well marked and looks like it will last a long time as sturdy rubber and unit indicators not due to rub off anytime soon.
Great soil, just water and your away, use Herbi's 444 and 284 maybe some wormcasting as your Vege's progress. Hydro Center in New Plymouth is fantastic, fast shipping and great range of products.
If you are looking for a great service and a fast delivery then look no further.
Your questions will be answered quickly and your goods will arrive even faster. Many thanks team.
