I hope there are responses this is interesting idea.

Hi Dale - wish I could help but I have never used any tablets. I have used both liquids and water soluble powders in an in-line dispenser with my drip system on the containers and with my soaker hose set-up in the big beds - good results with them and easy to do.

Are you looking at any particular brand of tablets? Are they supposedly quick-dissolve? I'd be curious as to how they insure consistent, even delivery unless they are pre-dissolved.

digdirt, tell me how you use the liquids and the water soluble ferts through your drip system.

Hi Dale - I have an E-Z Flo dispenser (link below) - learned about it on a HGTV show on fertigation a couple of years ago.

I just have to fill it with amount of liquid I want to feed - just like you would fill a hose-end sprayer - or a single dose packet of Peters or MG. It has an in-line filter for any undisolved particles if you use powders. I insert the unit between the faucet and the water hose to my drip system, set the dispense rate on its dial, and turn it on. It automatically dispenses the ferts as it waters.

MG also makes an inexpensive in-line dispenser they sell at Walmart. It screws on to the water hose on one end and the outflow takes either another hose, a soaker hose or a sprinkler head of various kinds.

Hope this helps.
