Re-read my last post for the amount to use. I stated in this thread several times. As far as using it the whole flower period, I don't know. When I called the company that makes Pysan, the lady on the phone said you could. I didn't want to try and find out. I think you will be the first if you do it. Let us know. Something tells me it will be ok. And, if it is this product will be the absolute best additive for a sterile resevoir. And its super cheap.

thanks rich.. this thread is the best. this slime stuff has set my harvest back about 3 times already as soon as i use the hygrozyme. i threw that stuff away. i recommend hygrozyme for rockwool growers who want to dissolve the roots in the rockwool so that it can be re-used. it seemed like hygrozyme worked for me when i first bought it. but after it sat on the shelf for 5 months in an environment above 80 degrees , i think it started to go bad. i ordered physan 20 and I plan to never be set back again to this brown slime. i believe the slime is some type of evolved bacterial biofilm. i don't think it's algae. ...but i don't have a degree in microbiology so i'll let the experts figure it out. I just want to annihilate the slime for good. what is the ghost's name from that movie ghostbusters that was made of slime. thats what this slime shit is... it appears overnight and bam your screwed. I JUST FOUND THIS ON A WEBSITE!!!! NOTE: SM-90 will inhibit beneficial bacterial colonization. in other words. sm90- will make hydroguard useless. I used both on my grows where the slime was. WWWOOOOWWWW

I did a little change up on my mother hydro system yesterday. Heres the scoop.

I have mothers in 5.5" square pots filled with hydroton. They are in a flood and drain tray with a recirculating rez. The algae has been very much alive in there for a long time now but I had learned how to control it. A chiller and Dutch Master Zone will tame it. I was still using Hygrozyme too because I needed something to eat dead roots in the pots because they get root bound quick, so you add the enzyme to eat old root mass and let the plant regenerate new roots.

So, here is what I wanted to do. I wanted bigger pots for more root mass for more clones off each mother. I wanted to turn my current set up into a top feed. Not necessarily a drip because I have open 1/4 lines running to each pot. So, I guess its more NFT. I have a recycle timer set to squirt for 1 minute every 15 minutes. The timer is great because it has turn knobs that you can set at what ever intervals you want.

Before I took things apart, I poured 2ml of Physan 20 per 10 gallons. I went double on the recommended dose. Today I can report no ill effects. The mothers look very perky and soaking up the light. I can also tell you that I did not flush everything out very good and I know there is still some Physan20 residue in my rez. I dont have a hydro system to try leaving Physan20 in the whole time anymore or I would try it. As far as my mother hydro system and I cant take that risk. I have some real elite strains.

The problem I have now is when I pulled the plants from the old pots there were a lot of rotten roots. I only have nutes and Zone in my rez right now and the pH and the PPMs are climbing every few hours. I think the roots rotting are causing this and it will not be long until root rot or the brown algae get a foot hold. I popped them in the new bigger pots as they were. This is where Hygrozyme comes in handy. It will eat up all that old root mass and make way for new healthy roots.

My course of action, I am going to wait until my mothers establish more new roots in there new roomy pots and then I am going to add the Hygrozyme to eat the old roots. Should take about 3-4 days for the enzymes to do their work from what I have seen. Then I will Physan20 the whole system and flush it out. Then I will go to just Advance Nutes and Dutch Master Zone and the chiller set at 65F. That is all that is needed.

Yes, SM-90 cannot be used with beneficials. Also, don't use Zone, H2O2, Physan20 and I wouldn't use tap water because of the chlorine. These all will kill your beneficials.

H2O2 can be used with enzyme products such as Hygrozyme, Sensizyme and the others that I cant think of. Actually, you can use all sterile additives listed above with all enzymes and H2O2.

All enzyme products can be use together with beneficial products; Hydroguard, Root Excelurator, Pirahna, Scorpion Juice, Mycorrhizae, Sub-Culture and the rest. Absolutely no sterile products with these.

Well, good luck getting your plants back to health everyone! The slime is the reason I went back to soil, myself.

It seems to me that Hygrozyme is only good when you absolutely need it for eating up the rotten roots when the problem pops up.Other then that it seems when using zyme it can cause algae,so it leads me to believe that I won,t use Hygrozyme until I get some root rot.It really seems that this thread has taught me the old catch 22 situation.You may be dammed if you do or dammed if you don,t
This thread really has me taking a lot better care of my plants and watching carefully for any bad stuff that may show up.It,s almost like starting all over again.I see it as a chnage from sticking the clones in my tables and takin, apeek at em form time to time to the point of actually having a problem to solve.In the end it will make a better grower of me...fingers crossed.Goin,into week two of a new show and everything is looking like never before.Usually at this stage I am cursing the brown herpe slime.
Hope we can all take something away from what we have learned here.
Richyrich my hat goes off to you for your diligence in doing a lot of reading and experimenting to try to bring this curse to at least a point where we can understnd the inner workings of the cause and effect of what plagues our hobby and hard work.
I personally feel good in the knowledge I have gained here..
*Hygrozyme is sold in Canada as Grozyme and in US as Hygrozyme.Don,t know if in fact it is made at one place and sent to different distributors to be sold from one source.The stuff I buy here in Canada is all written in French as it comes outta Quebec and I have noticed no two jugs of it are always the same.I do believe however it does have a longer shelf life then many additives.But the longer it sits the more it smells like beer with age.I will try it again this grow but not until three weeks before flushing time.I also will use it at about half strength or maybe a little stronger.I,ll keep close tabs on it to see if it does have any affect on the root system.
Funny thing with the Hyg,zyme is that I always had an idea that it was causing the alage but never really got it dialed in enuff to actually find any info that would substantiate my suspicion.I believe we are a lot closer to finding out if it is a product that is to be used with caution.
rant over
Good luck to all
be safe...

I have not added Hygrozyme in my mother hydro system for a couple of days now. There for sure are some old roots rotting. I can see pieces in my rez. Funny thing so far is there is no herpe slime (brown algae). My pH has stabilized for the last 24 hours. The only thing I have in the rez since I changed the system over is Dutch Master Zone, RO water and Sensi A + B Grow. Oh, and the chiller at 68F. Lets see what happens over the next few days.

Here is the conversion.

Purple Kush for next round. Can't wait.

good job hope all goes well

4 days since this conversion above and no herpe slime. I think I can say its gone. It would have made its presence known already. It will always change my pH quickly and so far it is rock solid. Also, the algae will always grow on my pH probe like the pic below and it has not thus far.
