i think honestly with all those items listed you could make your own at half the cost if not even cheaper
Get yourself some Rose Nutrients to make the color colorfull... make's the water soft........ but dont add over 2ml in 1 liter ! you'll burn the plants.. believe me i've done it and i was so anoy'd...
Do you have a kettle? If so take off the lid and look at the heating element (usually an elongated U shape) if its covered with white stuff that may also be at the bottom of the kettle you have hard water if its squeaky clean you have soft water, that is unless you just bought a new one. Hope this helps.
