If you do a quick search on here: "PMDD" there will be heaps of topics and information.

EDIT: I think he means PMDD. So search PMDD.

What is 'ppmd' ?

I know about pmdd (Poor Man's Dosing Drops) and I use it when ever I have a planted tank set up.

[Tom_Shannon]

my bad was in a doing other things when i wrote that all fixed now

i have searched but want peoples opinions on it only seam to be able to find people saying that they use it

[Caryl]

In that case, I don't use it so can't give you an opinion on it 8)

Sorry..

I like it and used to have a lot of success with it. I think flourish works better but at about 1000x times the price I would go with PMDD or these days I now use PPS which is very similar but separates the macro and the micro solutions into two bottles.

The biggest problem with PMDD is supposed to be the chelated iron in the trace elements will react badly with the Potassium and Magnesium which is why some people now use PPS which separates them out.

I am not a chemist so forgive me if I get the reasoning wrong its just the way I understand it.

PPS Ingredients list

Macro Solution

In 1 litre distilled water add

59 grams K2SO4 (Potassium Sulfate)

65 grams KNO3 (Potassium Nitrate)

6 grams KH2PO4 (Mono Potassium Phosphate)

41 grams MgSO4 (Magnesium Sulfate)

Fill with distilled water and shake well. Let sit overnight.

Dose 1 - 1.5mls per 50ltrs every morning just before lights come on

Micro Solution

In 1 litre bottle:

80 grams of CSM+B or equivalent trace element mix

Fill with distilled water and shake well. Let sit overnight.

Dose 1 ml per 50ltrs every morning just before lights come on.

I have net paid for it yet because the hydroponics store says it to small a quantity to worry about. Normally I flick him $2.00

LOL. Got you thinking have I. Found a clause with the flourish you have changed to its more of a micro nutrient not a macro so you would have had better growth with the sera fert. Im currently using the flourish NPK range ,nitrogen,phosphorus & potassium also adding iron for the red plants. Cant comment on the growth yet only been using it for a week now. If this doesnt go well ill be looking into making some PMDD to. Have alittle bit here i got off hans if you want to give it a go.

[Tom_Shannon]

its funny you say that about the sera fert as since iv stopped using it my chain sword has turned to poo im just using flourish at the mo. yep keen to use some and see how it goes everything else is growing well especially the red mac.

[LYNDYLOO]

I've just bought some PMDD off Trade Me, will let you know how it goes, currently using API Plant Food and DIY CO2.

[dbden]

Red macs thriving on the high iron in flourish comp its 32% compared to .153 % in sera fert.

Free on sunday come grab it got to get the tank cranking in the next month. Check out the new set up to

[Tom_Shannon]
