I think the problem everyone is missing is that the good bacteria has to take hold on the system first, before it can destroy the bad bacteria. it doesn't work like H2O2, you can't just dump it in and expect it to work right away. I wonder what the directions on the bottle say to do? the bad bacteria can probably take hold on the system faster then the good can, so they just end up killing off the good and you end up with the problems.

The directions tell you to use a large dose the first application, you can use it at like 30x the normal amount you would use. After the first one, you drop the dose a ton. The reason they say to use a large first dose is probably to get a colony going asap.

So if you use SubCulture from day one, when there are no "bad" bacteria, then you will never have a problem. It is about preventing it from ever happening, not getting rid of it once it is there.

how much is it at a grow shop normally, and do you know about how long it lasts with a 5 gallon res? I'm almost out of nutes, so I'll be taking a trip to the shop this weekend, I'll see what they have

A lot of the shops will sell individual packets. It comes in a container that has a bunch of packets in it. I don't remember how much it was exactly, they are like $10-$15 each i think. And the whole tub is well over $100.

It says on the instructions that you can use up to an entire pouch per 5gallons. I only use like 1/4-1/2 tsp per gallon. I am not sure how much is in each packet, but it will last a while. I have only used like 1tsp per gallon at the most. I have never had a problem with root rot, so I never felt the need to do the giant first dose. If you are not having any problems, then just the 1/2 tsp per gallon should be fine.

thanks for the info. is this the stuff that helps with algae too or is that something else? I don't think I've sounded like such a noob in a while. lol

I have no idea about the algae. If you can just keep the light out of your res, you will not have algae problems.

just started subculture and hygrozyme. one of the them is def helping! not sure which one

res temp has been constant 75 during day and 72 at night. the weather is turning though and i am honestly kinda worried about how its gonna be when its freezing outside. the res went from 80F one week to 75F the next.

I'm sure its been mentioned, but you can just put an adjustable fish tank heater in there. Just make sure you test the temps before you just set it and leave it.

I had to put a heater in my grow room to keep the temps up. if the res is in the room, you shouldn't have to worry to much about heating the res. just keep an eye on things

cool air temps in the room can stun growth. I noticed it when the temp went down to 70 during the day inside.

yea right when october hit and the temp dropped in my area there was a noticable difference inside. Im thinking that a heater might be nessary as the temp drops as we get into winter. My only concern with using a heater is how much energy and amperage that use. I know most heaters are over 1000w even on the lowest setting. and i know they need a steady high number of amps

If you can get away with it, have your exhaust on thermostat so that it will kick off when its too cold, and will come on when it warms up. This way you don't have a heater in your room using extra power, and it will actually save you power by having your exhaust off some of the time.
