Critical Super Silver Haze - 3 Plants

Hey guys I have been trolling through the website and I am finally at the point where I can begin a good grow. I have already germinated 3 seedlings of Critical Super Silver Haze (CSSH) and I am prepping them to be transplanted into HG Waterfarms. In some of the pictures you will see tomatoes, which will be in the same grow tent with the CSSH. I will focus mainly on the CSSH plants but will occasionally update the tomatoes as well. I will say this. This is my first grow of MJ and it is also my first time using hydroponics.

The waterfarms have been modified to have larger holes that I drilled out for better root access to the reservoir and I have also added an air stone to each one. The aeroponic effect i read about will provide the necessary air in the water to maintain healthy roots also while continually mixing nutrients during the weekly cycle.

I will be using floragrow series from HG. I will keep PH at 5.8-6.2 and depending on the water I will probably have a starting ppm at 180 which is high. I have considered getting a reverse osmosis machine but wonder how well they work. Any thoughts on that please post below..

These seeds are about 5-7 days old. I have maintained 65 degrees to 80 degrees with the average being 75 degrees. I have it in a terrarium as you can see from the pictures I am posting. So far I have used PH water and I did add a small amount of root start to it, seemed to work real good.

The main setup, which will not be setup for about another 2 weeks, is going to be in a basement. It will be located reletivatly close the heater and ac unit. The reason for this is because there is an inflow of air to the ac/heater from outside and then there is a tube that pushes hot air outside. I will set up the 4x4 grow get the ducting all worked out but I have to figure out how to connect the ducting to the PVC piping that is the outlfow of air. Any help on that would be wonderful!

Let me post some pictures.

Ok so I am a new guy and probably an idiot it seems cause I decided to use Microbe Hydroponics sample pack I got from a buddy. White shit has been growing all over the grow medium. Should I try and spray it with a hydrogen peroxide mix to get rid of it? Or should I just scrap these plants? I also uploaded some of the past few days. The one of me holding the Super Silver Haze with the white stuff over the grow medium is the one I'm worried about.

(Please ignore my tomato plants lol, they seem to be doing fine

Ok after some online research I found that the white stuff is Ecto Fungi (the shortened version of the name). It is to help transport nutrients throughout the roots of the plant and is apparently a good thing. I will post updates on it.

When I first noticed it I will say it scared me. But looking at the color of the leaves and the the noticeable growth in 3 days I think I will let it run its course.
