    Hi all,
    been on a hiatus for a couple years and realized my favorite micro, Tropica Master Grow aka Tropica Plant Nutrition, has been discontinued. I know people have used CSM+B as a micro but am curious how it compares to TMG. I had always thought the concensus was that TMG was better. So.. what's your favorite micro?

    I dope the CMS+B with some Fe DTPA and some Fe Gluconate myself, around a 3:1:1 or 4:1:1 ratio CMS: Fe DTPA: Fe Gluconate.

    So say 3 tsp of CMS, 1 tsp of DTPA and 1 TSP Fe Gluc in 500 mls of hot tap water.

    Source for both Fe Gluconate AND Fe DTPA?

    After some searching, it seems the Fe Gluconate has a weak chelator which I would guess is to 'spike' the iron content while the Fe DTPA has a stronger chelator for a slower, more sustained release into the water column. Am I understanding this correctly?

    Also, I'm having a hard time finding a source which carries the CSM+B and both the Fe Gluconate and Fe DTPA. Most places have the CSM+B and one or the other of the Fe types. Can anyone point me to a source that carries all 3? (I'm cheap and would prefer to pay shipping only once.)

    I recently searched as well and ended up buying them from different places. You can buy higher quantities to last you a long time; either way still cheaper than TMG.

    While you're at it you may also want to buy some MnSO4. It is debatable as to whether or not it is really needed but you might as well add it. Do a search for "the good shit", there was a lot of good discussion about it.
