just for the fun of microscopy, here's tonight's specimen from a lacto b. serum rice-wash inoculum (500x)...

read about the soil food web. Googling this or reading the book, the soil food web by jeff lowenfels will give you all the evidence and knowledge you need about bacteria and fungi. It actually is pretty standard to all gardens and dirt and some special moves should be made with comtainer gardens and or any soil where chemical ferts or P products over 10 have been used.

Chem salts kill your beneficial organisms in the soil. I use rooters myco for 10 dollars, and super plant tonic, and worm castings and compost tea (which is all you ever rally need) to get the beasties back or into my soil. Also I feed them some molasses to feed them. Once in the soil the plant will attract the ones it likes. Most annuals will choose an endo fungi and the bacteria to go along with it. It will need bacteria more than fungi in the soil but all plants need the myco for the roots.

Plants without myco are pathetic I have seen in many photos, right next to plants easily twice as big. It is a big deal to have myco, also let ferts need to be used.

Chem salts mixed with organics is not as harmful as some would be lead to believe, and I'm mainly one of those try to grow 100% organic guys (just for the pure convenience factor and ease of growth) There have been more recent studies that actually show chems salts are taken into the plant easier with a mix of the two...hmm let me find the link to the University studies.

I find it pretty interesting actually. To me the biggest problem people have when trying to grow organically is they let the soil get to dry. That's a huge mistake I think with any type of soil/soil-less medium, organics or not. I'm not sure how the whole let the plants dry out then drench with water myth started but I never let mine completely dry out.

What's ironical about the organic purists, is that it's the chemicals in the organics that make them work. (shhhhhhh, let "them" go on believing.)

Don't believe the propaganda. "Chemical" is not a bad word, it's a lame mantra.

For my soil mix I use fox farms ocean forest with 20% perlite, a cup of pulverized dolomite lime, and 1/2 strength fox farms marine cuisine. I also use the fox farms nutient trio (grow big, big bloom, tiger bloom) along with molasses and cal-mag plus (RO water) for my nutrients. Would any of these products work with my current schedule?

Well they dont hurt your plant so why not. I use a Myco additive along with Fox Farms liquid trio and even though the nutes are not 100% organic, my myco colonies are not affected in any way by the ferts.

So, what's the final NPK values that your plants see?

A cup of lime in how much total mix? Why are you using cal-mag when you have alot of dolomite?

I'm not sure the final npk values but i can look it up. I cup dolomite per 1.5 cubic feet of ocean forest. I use the cal-mag to supplement of course, my leaf tips were looking bad and the leaves were generally poor looking before i started the cal-mag.

---during flower the tiger bloom is 2-8-4 and i use 2 tsp per gallon, big bloom is like .01-.3-.7 at 1 tblsp per gallon.

This is kind of a dumb comment/question, but does anyone think it would be possible to grow truffles in the roots of cannabis plants? I know they're mycorrhizal fungi and i think they're usually grown on rosemary...

What product do you use? looking for something that will live in the solution i feed the plants.

-Abe i always thought truffles grew around oaks not too sure though. I really don't know much at all about the subject but if the conditions in the cannabis resembles those in the truffles natural habitat i dont see why it wouldn't work.

A cursory guess is that's way too much Ca and not enough N.

I use Super Plant Tonic from Blue Mountain Organics. You can buy from them on Ebay. Theres also a thread about their products in the Organics section.

Heres a product description of it:

And you do see positive results? Have you compared plants grown with and without it? I was reading the dosage instructions and it says i would use 1 gallon for my 5 gallon pots each weak. Do you feed it all at once or between the seperate waterings? Also do you mix it in with you nutrient solution, or separate? $7.50 is a great price btw.

thanks

I havent done a side-by side test with it. The best way to really see if they make a difference is if someone did a grow from clones. If I ever get a chance to do so in the future, I will definitely do it.

Yeah, I do feed it all at once. I try to do it weekly like they suggest, and if it happens to fall on the same day I am using nutes, then I just mix them together.

It'll last awhile. Ive still got about 20% of a bottle left. That has lasted through 81 days for my first grow, and 50 days for my second grow that is going on as well. 15 plants total.

You can buy it as part of their package deal. Veg nutes, flower nutes, foliar feed, and spt for $25 I think. Pretty good deal Id say.

So Dave,
Do you follow the FF feeding schedule?

So Dave,

I start out at 1/4th strength and move up to 1/2, then full strength if plants dont get burned along the way. Some plants dont like full strength like a sativa, so always start low and work your way up.

Why would anyone follow someone's else's schedule or a chart? No 2 plants are alike, no 2 gardens are alike. Don't mean to be rude, but I need to make a point directed at all new growers, not just you. If you have to follow some chart or schedule, you shouldn't be growing! Why? Because you have allowed someone to manipulate you and your garden will suffer for it. Empower yourself, learn what makes a plant tick.

Plants are dynamic, they can't read, they only react to what's given to them. Naturally a 4" tall seedling or a plant that is 3 weeks from harvest (barely bulking up) will not REQUIRE the same amount of salts (nutes) that a plant will that is putting on 2" of height a day during its stretch (bulking up) phase.

Does this make sense?

I have read you rant on this subject countless times. In this instance I was referring to the nutrient schedule in regards to the fungal colonies in the super plant tonic. My aim in asking the question was not to find information about feeding, but whether the SPT microorganisms could survive in the high salt nutrient solution suggested by fox farm.
