I just got a load of seeds for my allotment and I think I got a pack of 20 varieties, around 14,000 seeds for something like £5-10. Good solid varieties, F1 crosses etc.
I did go mental and buy just 10 specific chilli pepper seeds for the crazy price of £3.95 but they were special and I really wanted them.
The guy in my local shop says that around 50% of the products he stocks have one purpose, they feed the greed that some growers have. Ultra mega big bud juice, or Super size me bud spray etc at £20 for 500ml that is just repackaged seaweed extract that is £5/l from the garden centre.
There is a very small number of products that I buy from a hydro shop, people have been growing plants for a long time and good products that actually work are available anywhere and are also cheap.
Seeds will go the same way. When people realise that you can get as good a plant from your mate down the road as you can from the mega seed company the mega seed company will not sell any seeds.
Except to the greedy and/or stupid.
