I use it. The whole line-up. Don't skimp on the additives like root juice, top max, Alg a mic etc.and you should be fine. Don't add other stuff like Kool Bloom and all that. They are likely to cause fertilizer incompatability issues. They have bloom boosters and Root additives all included in the complete line so adding more will throw off the ratio they have designed. I do add Sweet and
hygrozyme but all others I've tried have been counter productive. If you do use Sweet you will want to use half of what they recommend and see how it does. This will depend on your water.
These nutes are molasses based and have a friendly smell compared to others. They do work well once you get them figured out.
After you get a couple good runs under your belt you may be able to add some Organa guano and Guano add. They are made to add to existing ferts and do work well with bio-bizz. Remember to go easy. I have a very specific way adding these things and do not recommend it until you have the regular line-up rocking good and are comfortable and confident in it....;)
oh yeah, I have never used the bio-heaven.
