Blunt's first DWC (closet) grow
Hello all, I am new to this forum and to the art of DWC growing so take it easy on me with my first grow. I would appreciate any informative feedback or advice you can give me but if you are going to criticize please kick rocks. I've read many of the DWC threads on this forum which helped me ALOT so I took what I thought I would need to help get me started so here it is, Blunt's first DWC grow! Also, please feel free to subscribe! Thanks and I look forward to the next few months.
Just a heads up but I don't have a fancy tent, exhaust fans, carbon filters or any of that stuff. I own my house and have to make due with what I have, the only pain in the ass I will have is I have to use a dehumidifier when Flowering when the lights are off and putting up with the smell..even though I look forward to that!I just got through week 1, I am watering the top of the rockwool twice a day and I started the light about 3' above the plant and within the last week crept down to a little under 2'.
*NEWBIES* The main thing I've come to learn as of yet when setting up a CLOSET grow for DWC (almost 5X5) is it has to be a controlled environment, I had serious heat problems when I was testing out what I had and I tried to fix it a few different ways (Evap Cooler, Fans, leaving door cracked, ect..) and I also came across a couple of threads of people running into the same problem. If you're a rookie like me, don't rush it and do what you have to do to make it work, stay away from the short cuts and don't do cheap fixes because I had to learn the hard way! Oh yeah..have PATIENTS too.
DETAILS:
18/6 light schedule
400 Watt MH/HPS light.
RT: 75-78 degrees light on with humidity ranging 44-51%. 71-74 degrees light off with humidity at roughly 63%
Water temp: 66-72 degrees (using an ice pack twice a day to keep temps cool)
Water PH: 5.8
Nutes: GH Fluroduo
PH Meter and a PPM Meter that also reads the water temp
4" air stone
2 Gallon cooler to start, transfer to 5 gallon if needed.
Hydro seed, unsure on strain and PRAYING for a female.
Here are some pics!
Week 1
Not a great cell phone picture of the closet and it makes it look like the light is really high above the plant but it's just to give you guys an idea of what I'm working with. I have a few fans set up but they didn't fit in the picture.

The answer to my heat problems! A 5000 BTU Portable Air conditioner/dehumidifier I purchased on Ebay. I was lucky with the fact on the opposite side of the closet's wall there is an AC closet with 2 exhaust pipes that vent outside through my roof. I just vent into it and boom..no more temperature problems.

HAPPY GROWING!!!

Looks good!
wrap that exhaust tube with insulation and it will make a huge difference. you say nutes are you feeding yet? it is too little.
No, not feeding the nutes yet but I wanted to go ahead and put what I will be using up. Thanks for tip on the insulation!
UPDATE
It's been 10 days exactly since I put my bean into the Rockwool and this morning I had two roots dropping out of the bottom of the net-pot. I flushed my DWC, added distilled water, aquashield and started my nutes at full.

However, I did notice my PPM's were high after I did all this (around 650PPM). I noted from a thread you add nutes when you need to lower PPM so I did this and now they are around 750PPM? Any help would be appreciative!
dude, when you are measuring ppm you are measuring the amount of nutes you put in the water. more nutes equals higher ppm, less nutes or more water equals less ppm. little baby plants with new roots do not like full strength nutes. start at around 250-300ppm and work up.
Thanks bro.Originally Posted by superstoner1
Just an update on the start of week 2.
I flushed the cooler after I had a problem with the PPMs, straightened it all out and everything seemed to be okay. The last couple of mornings though it has wilted over night but once I get home from it's resting period it's always perked back up, I'm guessing the light was too close so I moved it up to about 24 inches. I've also noticed like a little brown ring that looks like a water line starting to form around the cooler but I always clean when I see it coming back, not sure what it is though?
WEEK 2

Ya man, when I had my seeds germinating about a month back, I actually read the the seeds contain enough to deal with the first 2.5 weeks by itself. I listened to the advice and it seemed sound as a pound. Make sure if you do decide to use nutrients start out with 1/4 of the recommended or even 1/8 since it's so young and work your way up until the roots hit the water. Then you can bump it up, make sure and catch any signs early though so that you can adjust accordingly. From the pics looks like you caught it in time, little bit of nute burn. I remember when I first started I had the problem of not being able to leave the seedling alone, which can stress it out quite a bit. I read you have an air stone but do you have a nice pump to go with it? The more oxygen the merrier I've come to find. Hope this helps =)
Thanks, Dontcough! I noticed the nute burn as well and the roots just hit the water, should I leave the PPM where they are at (300 PPM) until the plant grows more and the nute burn goes away? As for the oxygen, I have a 602 GPH Sun Leaves air pump and it seems to work well, I have it pushing a massive 4 inch air stone right now and I could always add another one to the DWC if necessary. I'm sorry if I am missing it but when you say the seeds contain enough to deal with the first 2.5 weeks by its self, what are you referring to?
