Just got some of this on-line for RO/rainwater. I have a small countertop R/O unit that gives me all I need. Sure can't count on rainwater out here. Directions are 1 tsp per gal. Any of you that use this stuff, do you go full strength or cut it in half. Is this all you use or do you trade of with other ferts like Gro-More

I've been using it for a few months, Ted. I do use it full strength when the weather is warm and alternate feedings with potassium nitrate plus epsom salts (the product is called UltraClean Super plant food from a company called "Food Rising") which I started using last year. As the weather cools off in October I taper back the fert to half strength and space out the feedings to a week apart or more.

Can't really tell you if it's "working" or not just yet. I am seeing some good looking new growth on a lot of plants, though. We had some cool nights well into May this year, so new growth was sort of slow starting up.

Ted, can you tree mail me the particulars on your RO system , please? My rainwater is going down fast, and this is only the beginning of summer.

Kathy, @Boojum has an RO system. Perhaps she sees this message and chimes in.

Glad to get the info to you, Carol.
Well, hot and humid, for SoCal, today. I wrote an article for Garden Ideas some time back about using your A/C run off for really good water. Filled a 5 gal jug so far today

Ted, when I lived on the Chesapeake Bay, all I had was a well that pumped salty water...trying to establish a garden was a challenge...until I discovered that my two AC units ( that were on elevated platforms above the flood line) produced enough water to fill 2 50gallon drums...EVERY DAY during the hot n humid summers. I also had a dehumidifier in the 'basement' of the elevated house that produced massive quantities of water which the dog enjoyed.

Don't know if I want that kind of humidity

Lindsey, I didn't know you lived on the Bay, you have been all over. We lived on the Wicomico for 10 years but we sailed out of Cambridge.
