When you use a molasses = any straight molasses, in hydro you risk fermentation and other problems so.....
Molasses - alone, should not be used in hydro runs. Care should be taken if you use it in soilless too....Rule of thumb being, If you don't have a living bio heard in your media......Skip the molasses...
You might consider a "Sweet Raw" like product, in place of molasses......It works on several levels in all styles of grows...Increases tric and terp production.
You can make your own....
Botanicare's Sweet Raw.
65.00 a BOTTLE = get real......I can make it for less then a buck a gallon!
You will need and opaque bottle - gallon size
1 gallon RO water
8 TBL Epsom Salts
1 1/2 tsp DARK Brown sugar
Pour water into the gallon jug. Now pour 4 cups of that into a sauce pan.
Pan on stove and bring to a boil.
Add the epsom and the DARK brown sugar and boil for 4-5 min stirring nonstop till done.
Remove from stove and using a funnel, pour the mix into the bottle of water...Shake to mix and use like this.
week b4 bloom = 5ml per gallon of feed
week 1 = 10ml
week 3 = 15ml
week 6 = 20ml till finish
