hi all,

is there a test kit for Iron and Co2? this is for monitoring the plants of course. went to animates today and all they have is the usual ammonia, nitrate, nitrite test kits.

Yep you can, they might need to order them though.

if you have a Kh and Ph test kit, you can use this chart for Co2

wow! thanks!! what about Fe Iron test kits?

HI Shuih....

Hey be carefull with the iron test kit. I bought one a while ago, tested water yep iron was low! so thats great BUT once i organised a good PMDD fert, plants grow like crazy, hardey used the test kit ever again, so it sitting 90% unused, and.... expired.

Dunno if it is really useless, maybe some one who has been using kits longer can elaborate, do the reagants deteriorate once opened??

For my ten cents i would happily pay the $1 if the LFS would do an iron test, better than paying the $40 ( i think) for the Fe test kit.

ok ...thanks for that. what is PMDD fert? because i dont mind my plants grow like crazy

Take a look at this,
