From my relatively short experience's of buying 'brand name' or 'discount shop brand' seeds from the usual retailers, ie: garden shops, bunnings, clearance style shops etc... I have found they are often very hit and miss. ie: Using the same packet of seed for 2 plantings, 2 weeks apart - 1 planting had approx 80-85% germination whilst the second planting only yielded 15-20% (including visavera). I have had to supplement my efforts thus far with purchased seedling stock.
I do acknowledge different propagation mediums can and do influence the germination percentages, even of a particular species of crop. Along with a whole other list of input variables from water saturation to seasonal conditions and even moon phase.
Personally concerned, I would love to get to the stage where I am producing &/ mixing my own high yielding compost medium in suitable quality, volume and in a self sustainable way - but I am not there yet.
I thought this topic might have been rolling around quietly in a few of our minds.
What & who do the worlds larger commercial hydro farms and producers use ?
So my question is 2 part and will vary through out the worlds regions....
So i'll use the Australia/New Zealand region as my question basis....
What about in the USA / Europe / Asia / South American Regions ?
Who would you consider the best producer/source/contact for commercial quality seeds in Australia ?
(commercial quality obviously would come in commercial qty's - group buys any one?)
What propagation medium do you consider best quality and value, offering the best performance across the varieties of crops ?
(not as regionally specific though good info for all)
