Ok, What the hell. I got BMO products back in aug. I kept the spt in the G room, in the shade lid cracked open and it still went bad or non active. tried the trick to reactivate it. no luck.. I got my new bottle today.
Can I use a small amount of the new SPT to reactivate the old bottle? I strained out the large floating fungi mass. It's over half a bottle.
also is the heat in the G room bad for BMO products? is the cool temps. better for them? I thought I saw on here a thread about this once. but I can never find chit with the search.

Thanks In Advance

Dunno about your situation. I store mine in a drawer in my gw. I'm guessing it was the light more than anything. Good Luck, I love SPT!

GrowBabyGrow41...... Exposing any organic fertilizer to direct light will kill the active organisms in it. If kept in a cool, dark place, it will last much longer. You can refrigerate SPT to keep it good for a very long time; just don't freeze it.
.
The floating fungi you strained out, was millions of fungi in a colony. If they were exposed to above average temps above 75, this increases their feeding. The faster they feed, the quicker the deplete their food source. These little critters have a natural hard times defense instinct. When food gets low, or temps get below 45 they slow their activity to the point of suspended animation. Waiting for things to change.
.
So, the reduced activity, is just that. It does not mean they are dead. If the colony is still (white) it's still alive. After they die, as a colony, they would turn dark brown and eventually black.
.
Storing organic ferts or supplements is not like dead chemical ferts, a cool, dark place is a must. Under a kitchen cabinet or, like me, in the garage work bench works just fine. Even in the frig, on the bottom shelf in the back.
.
Don't chunk that old bottle of SPT, pour it into a compost pile and let it improve it. Or add it to a five gallon bucket half full of unchlorinated water, and two ounces of molasses and bubble it for a couple of days. You may find, it's still alive and well, after all.
.
Hope this helps....
Keep it Real...Organic....

Thanks for the reply OSG.... I had unreal results with the SPT the first time i used it.. The clones grew off the chart. roots grow so fast ,I can't keep up.
The old bottle still has white, well a lil brown I used Molasses to feed them. when I tried to reactivate. I get some bubbles in the bottle and very small amount of pressure when shaken with the lid tight for a bit...
I added about 9 ml of the new to the old bottle... I'm going to bubble it and see what happens.. I think it's trying to reactivate..
On a different Note. I bubble everything... what can I use to stop the slim that grows on the bubble stone???? thought about bleach water ,but if I dont flush it enough it might kill good Microbugs.....??????anyone!!!!!

Thanks IN Advance

GrowBabyGrow41..... I just pull off the slimed up airstone and sit it the sun for a couple of days. The slime dries up, and comes off with an old toothbrush quite easily. Since, I just use the cheap ones from Walmart, they come in a two pack. So, I just rotate them, until the SPT breaks them down - which seems to occur ever few months.

When you say "cool", what kind of temps are we talking about? I first had in my grow closet, but I figured that it got a little to hot in the top (probably around 75-80), then I saw this and put it up in the attic, where temps drop to about 40 degrees. I currently have it in the back of our closet, where it is very dark, but the ambient temps are probably around 65-70.

Zombie1334.... Most organic ferts, supplements or inoculants stay fresh longer - if kept between 40 & 70 degree F - (that's cool). Above 70 speeds up bacteria action, below 40 brings it to a halt, 32 and below - can kill bacteria (some not all).

Thanks for the Info.
I use vinegar to lower water Ph. is that ok to use with BMO products. Ie. SPT????

Very good question. I've heard not to use any ph buffer with organics.

GrowBabyGrow41..... I do not use any type of pH down with the SPT. I do with organic ferts, just not root inoculants like SPT.
.
I hear these little micro-beasties are very tough and can survive harsh conditions like pH extremes, but I have not tried it. The SPT when added to my water, drops it to a 5.8 from it's orginal 6.4 So, I have had no need to adjust pH.
.
An easy way to find out - mix up some SPT with unchlorinated water, pour some into a soda pop bottle (fill it only 3/4 of the way full) - adjust it's pH - then add 1 tsp of molassess or table sugar. Leave the cap on that bottle loose. Wait 8 hours, by then any chemical reaction between the molasses or sugar & contents will be completely done. Then tighten the cap, place it in a pail or bucket (in case it swells & burst) and leave it there for 24 hours.
.
When you loosen the cap that next day - if presssure escapes - the micro-beasties survived the pH adjustment - survivied & multiplied - the pressure is their methane escaping. If no pressure escapes, when you loosened the cap - the pH adjustment killed them.
.
The first mad scientist to try this - please chime in with the results.

Hope this helps....
