The 5 part salt system is Dry Nutrients bought in 50 lb sacks
its called 5 part because its made from 5 things
#1 Calcium Nitrate
#2 Potasium Sulphate
#3 Potasium Nitrate
#4 Magnesium Sulphate
#5 Trace elements
These raw nutrients are made up by weight into a grow or bloom solution. A 5 part salt system can only be used with hydoponics and cant be used for soil or coco grow mediums. It is a very cost efficient way to make quality nutrients.I can post the recipe if anyone is interested ?
@jollychap,
I consider it a seedling for the first two weeks and then go into Veg week #1 when the seed is showing roots outside the peat puck or 1 inch grodan cube at which point I transplant them into the 3 inch cubes and when they show good roots they go into the 1.5 gal pots with loose rockwool as the medium.
