Advice on fertilizer injectors
I humbly ask for advice. I just got a new paper catalog from Charley's
Greenhouses. In it they list two fertilizer injectors (if you don't count
the non-adjustable educter). Does anyone use these? One costs about $70
and the other about $350. Is one really 5 times as good as the other? What
do you use?
Thanks
Dave
