We can get good quality T15 , Basf material. Plse revert whether it is widely sold and accepted in Thailand esp in short term leafy vege growing area as this product contains high nitrate content (6% out of 15% N) which boost vegetative growth fast.
Fyi current rosier red T15 contains only 2.8% (0r 18.66% equivalent) out of the 15% N in the product. That’s why vege initial growth is slow. Borealis colourless T15 contains 6% ( or 40 %equivalent) in the product in terms of nitric nitrogen.
I think you should consider this high nitrate “N” grade esp for short term cash crop. Also when rosier may decide to eventually supply colourless product. Plse give a thought to it n revert
