Perfectionist needs help perfecting.

So here's my story. First off, i'm new at this. First timer and I am trying to really get it right.

I have a bedroom in my house that I use as my office, I have turned the closed into my grow room. My light is sealed, bringing intake air from my office room and exhausting it into my ventilated attic. I have a 165 cfm fan to suck air from the room and blow it directly onto the bulb, then at the top of the line in the attic i have a 400 cfm fan sucking blowing air into the attic. The reason for both of the fans is that when there were no plants in there we couldn't get the temp low enough with just the green fan, but now that I have plants and fans in there circulating air I only really need the 400 cfm, but the 165 works well at night to keep the room at a constant 80is degrees (if i use the 400 in the winter in Montana it cools the room down to about 71, and i'm running co2 so I like to keep it a little warmer).

Since it is so cold right now outside I don't really want all the warm air to be sucked out of my house, so I added another intake to the room to suck air from the attic. I figured this would allow me to use the smaller fan since the air was colder, and not have to suck the heated air from my house. It worked perfectly, except for the condensation on the intake hose and fan. This is my first question. How can I eliminate the condensation? Or is it ok for it to be dripping into the room? I'm not really comfortable with it. The other question has to do with what I saw when I went into the attic. The nails hanging down from the shingles all had little ice sickles hanging off of them. I don't spend my time up there, so I don't know if that is common or not. I don't want black mold up there. But I hear all the time about people fanning air from their homes into their ventilated attics to cool them. What is the truth there?

Now on to my girls. I started with three mature veg clones (2 taller looking a little yellowy at transplant and one bushier looking dark and healthy). I transplanted them from soil into perlite, and I'm using the Hempy Method. There is lots of new growth on all of them, the bushier plant looks good, but the two taller plants have some leaves happy, some leaves with yellow outlines, and some leaves that have started to burn and get crispy from the outside in. I'm using RO water on a feed/feed/water cycle. On feed i use 10ml ProGrow, 5ml Liquid Karma, 2ml Superthrive and 5ml CalMag. On water days I use 5ml CalMag and 5ml Sweet. I am just judging by weight of the bucket when to feed em. I skip a day once in a while.

Anyone wanna coach me? Tell me what i'm doin wrong?

Do you feel that you are doing something wrong? As far as the nails and stuff i have no idea. If your plants are healthy then keep doin what you're doin. There is no "right way" to grow. Actually there is, if you produce good buds then thats the right way lol. You said a couple of your plants were yellow. Were they yellow when you got em or did they turn yellow on you.

They aren't really yellow. They have some green leaves (a majority) and some leaves that have yellow on the outsides of the leaves, and others that have the burning on the very tip of the middle leaf. I don't think i'm doing anything wrong for the plants. I just want to speed things up so that I can get them healthy and flower them. I also don't want mold in my attic or a big electrical shortage due to condensation. In a nutshell I suppose my questions are:

1. How can I prevent condensation on my intake lines when coming from cold outside to warm inside?
2. Is it bad to exhaust house air into my attic?
3. What kind of deficiency/burn do I have happening with yellow outlines on various leaves and burning from the outside on others?

I have a sealed room and had serious condensation problems too. There may be better solutions, but what I did here seems to have fixed my problem.

I fixed it by having a passive intake in attic (cold outside air) and "attic exhaust" believe it or not straight down under the house. This keeps the attic cold with negative pressure. It also seems like it would be a good defense against FLIR.

From here, in my attic my intake and exhaust are about 15 feet apart.

On the exhaust I attached 12 feet of non insulated 6" flex tubing. This tubing runs right next to my passive intakes in my attic do somewhat cool the exhaust air. I then attached a 6" booster inline fan just to boost airflow. From there I attached 3 feet of insulated 6" flex tubing. I then attached the insulated flex tubing to the intake of my lights.

Now there are 2 air cycles

outside>attic>fan>basement (creates the cool neg pressure in attic)

intake>light>fan>exhaust>fan>intake

This made it so my light exhaust was attached to my light intake. It does not get too hot because the attic’s passive intake flows right over the non insulated part of my flex tubing, cooling it enough so it will cool the lights but not so much it causes condensation.

It has worked for a month or so now, with no drip. Make sure any metal (yes even flex tubing) is insulated if it hits both hot and cold air. If you have a metal connector between your room and attic for your flex tubing I would recommend using a plastic one or in my case none at all. I would like to come up with something for both hot and cold weather so I don’t have to reconfigure my setup every season.

Hope that helps.

Thanks. I'll give it a try.
