do you use subculture?

I'm currently doing a Ebb&flow with 6" hugos and considering using Subculture. Has anybody have any feedback regarding Subculture or similiar products /w hydro

I use SubCulture in veg and bloom in aero. I really like it cause the plants really like it :)

The root mass increased nearly 20% I'd estimate - resulting in healthier plants. One thing I noticed Is that pH will take a serious dive the first couple days(~4.5) and then restabilize around 6. It has a nice buffering action that helps keep the pH in the green zone. It does however contribute about 80 ppm to the rez solution which can cause problems when you work with very low ppms(like in aero).

In a side by side test - 18 GFM BX3 without SC vs 18 GFM BX3 with SC - the unit with SC yielded 12% more.

One further note - the rez will get cloudy and you may even get floaties. Have no fear, it will clear up in a few days, however you may want to rinse out your pump filter after it clears out as it may reduce pump performance because of brown goo in the filter. The goo is not stinky-just extra beneficials in the wrong place. The roots remain white and healthy.

A minor complaint is that they reduced the amount of material in each packet. It used to contain 12 tsp, but now only has 8. That extra 4 tsp is what I used in the veg unit - Hmmpt!

Anyways $16 per bloom run is still a good deal for even a suboptimal 10% increase in yield.

you can grow your own beneficial fungi by acquiring some good earthworm castings, mixing in 1-2 teaspoons of organic oat flour per lb and misting with ro or distilled water until lightly damp, then putting it in a container in a warm spot for a couple of days with a lid on or plastic wrap covering it to keep it from drying out...if you have good castings there will be white strands of mycelium and it will smell like a forest
