Hydro mediums generally never are meant to hold nutrients. The ways they work differ and have great variety, but all work on the same basic principal. In DCW buckets(like mine) hydrotron is just there for the roots to have something to hold on to while roots dangle into an aerated reservoir and the root ball in the tank is how nutrients are absorbed. In top feed systems, same where medium is just something for the roots to grow in and a nutrient solution is on a constant drip that runs through the medium and the roots absorb what they need. The list goes on and on, but the idea stays the same. The medium is just there to establish a footing for the plant, and all nutrients are constantly supplied from a reservoir or tank.

I will not be running a constant drip. But it will be a top feed set up. I just set it all up and ran some good clean water through it. Now im going to refill it and add some nutes and start the cycle.

I changed the setup a bit from last grow. Just the orientation of the tray. I also put in a make-shift bench which is nice to have in there when mixing up the nutes and taking measurements and doing adjustments. The light will be on 18/6 and is a bit above 3 feet from the plants. As i said the temp hovers between 76 and 78 with the light on. I'm curious to see what kind of growth these things get over the next few weeks of vegging. I added nutes and they are at 400 ppm. the water itself was at 150 ppm. feedings will be 2x per day for 30 min at a time. I will update this thing with pictures on Saturdays. Ask questions and offer suggestions as you see fit. Thanks for stopping by!

Seeing the whole setup you've got there I'm very impressed. Looks like you've got an air cooled light too. How come you don't have an extractor fan hooked up? Your temps are nice and low too. Damn nice setup, I'll be watching this one. Hey I got the same thermometer. What do you make of it? I'm not sure I can trust the outdoor sensor on it.

Thanks! I used it in my last grow and have noticed that it's a really popular light at hydro stores. I've not been given a reason to distrust the outdoor setting. That's the one I typically use as I hang that sensor from the top of the light and leave the sensor suspended at the canopy level. There is nothing to cool it down in there except a single fan and a deionizer. Last grow I didn't need anything else to control the heat or the smell. I tried to do it using minimal materials and it worked out. My biggest fear is the smell that I anticipate these plants to develop. I don't have anything to extract the air out of the room, but i just leave the door open all day and blow new air into the room using a regular fan.

I am thinking about getting another light. It would probably be 400 or 600 watt just like my current one. I like this ballast and found this auction...
http://cgi.ebay.com/400-watt-Galaxy-Digital-Ballast-by-Sun-Systems_W0QQitemZ250479825402QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3a51c2d1fa&_trksid=p3286.c0.m14
I think I am going to sell one of my camera lenses. I bought the damn thing in March for like $900 so I should be able to get plenty for it since its still practically new.

Very reasonable. I'm still keeping my eye out for second hand lights. A guy had a 150w flourescent and lampholder advertised for 20 euro, but it was 200 miles away. Might see if he's still selling it in next few days. A good bit of kit cheaps the best thing in the world.

THanks!! I appreciate that.
I woke up this morning and the temps in the grow room were 85 degrees where the plants are. not good. I came home this evening and checked the mins/max and the temps were between 73 with lights out for 6 hours and up to 93! Well. I think i am goign to try somethings here to get it cooler in the bedroom area. There's only one vent in there for the air to come in and two in the main living area so it's cold as fuck in here (living room) but much hotter in the other room. My bed is in the living room so I leave the closet door open when I sleep but I close the bedroom door to block the light. I am going to take up the vents in this room and see if that helps the temps.

What does high temps do? mine been floating in the 80's and 90's all through the last few weeks. Flowering seems to be going well for me. Have you added those lights you were talking about?

I added my one and only 400watt metal halide light on Saturday. That was the day 14 update. That's the only light I have planned on using. If I get another one it will be an unplanned spontaneous purchase. i guess that's redundant. w/e. I noticed that the end of the leaves on some plants were curling upward. That's a sign they are too hot. Hopefully over the next hour or so that room gets really cold. i'd LOVE to be able to get it down to 65 in there. I wouldn't keep it there now though. i think 73-75 is a good range to keep it in.

Ah I see. Leaves movint to an angle that's not 90 degrees to the lightsource so there's less light intensity per surface area of the plant. Phototropic. Makes sense.

I just checked the room again and it's a nice 73 degrees. I will reset the therm. and check the max/min in the morning. Hopefully it doesn't get too hot or cold.

i woke up and saw that the min temp was 70 and max was 76 or so. I closed the door when i was gone and the temp got up to 80 with the door closed. Also when i came back and opened the door it reeked of reefer. It smelled damn good too. I wasn't expecting that. That really scares me since my last grow didn't stink too much at all. I wonder if i am going to have to get something to take care of it.

I can't remember if I mentioned this or not but I can tell that the smell is going to be a problem. In the afternoon the closet door is closed for about 3 hours while the light is on and it gets up to 80 degrees but when i open the door it smells like some really good bud. So I might have to buy something to counteract this smell. I've been putting off getting a carbon scrubber because I don't want to deal with ducting all that shit. Plus exhaust from the room isn't really feasible since I have to keep the door closed and I can NOT cut holes in the wall or the door. Anyway, I think that over the next 30-45 minutes I will draw a plan for my scrog. I will be using PVC and I am not entirely sure what I will use for the screen itself. Probably something that would allow a lot of light to penetrate it. Chicken wire would probably be a good screen. I've seen people use all sorts of stuff and I think this is probably what I will use. I am thinking about adding some additional features to the screen just to make things easier for me. We'll see. If i have time I will go to the store and get all the shit i need as well. I have to bring it all in at night time through the complex back door so no one sees me. Just like i did with the lights and the tray. I fucking hate having to be covert about this shit. I wish I could do all this how I really want to. Maybe I should start a "Help FB obtain enough money for a downpayment on a new house so he can fill it with cannabis plants for us all to enjoy" fund. Plant update will be tomorrow evening. These plants are looking phenomenal too. Every plant that I attempted to germinated has progressed to the vegging cycle. So far this shit is going almost perfect. Ph is checked daily and topped off with distilled h20 when needed. Res will be changed every 10 days or so i think. Last time I think i did it weekly (on update thursdays) during the flowering phase. Not sure if i will do that again. It was quite a bit of work to do that shit. It will be even more time consuming this time since I have the tray and rez in a different - harder to access place. I am also still considering purchasing another ballast and light system either 400 or 600w.
