Yo guys, I've scoured the forums for months and the result has been three successful DWC grows with tremendous yields. My next grow is going to be the first where I will be continuously growing (vegging 3 motherplants all year round, and flowering 2 at any given time). It is also the first time I'll be using a SCROG, and considering the ludicrous yields I've had without a SCROG my expectations are big. The Grow Setup I posted pictures below so you can check it out. Its a semi-stealth grow in my closet. I have a ton of extra space and privacy and security isn't a consideration. I built a 4'1 by 3' (6ft tall with 4 1/2' grow space) box out of 1x3's. I chose 1x3's because their cheap and easy to cut. The whole system stands free of the closet around it so worst case scenario I can yank the whole system in a matter of minutes. I'm using the bubble bucket (Thanks to Rump) with a few minor changes. For one I found these 5 gallon bucket lids with 6 inch net pots built in. And I used opaque buckets so I didn't have to tape them. Ventilation I don't know if you can see from the pictures but at the top of the box is a 3ft by 1 ft opening that I'm gonna use as a vent. Besides that the system is almost air tight minus cracks around the door I'm using. Lighting 1 400w HPS with chrome reflector ballast for 2 plants. Nutrients I'm using the Lucas Formula with water add-back and flushing every 10 days. I'm using distilled water with a PH of 6.7ish. Germination/Cloning Nursery I started germinating a handful of bag seeds from some crazy chronic I had a month ago. I bought this sweet little nursery at the hydro store by my house, it fits like 75 rapid rooter plugs. Right now there are 6 in there, all bag seeds, and 3 have sprouted so far. These are going to be transplanted to soil pots and any females kept as mother plants. I have access to a sweet ICE motherplant. I'm going to take a bunch of clones from that tomorrow and drop them in the nursery. I'll be using 2 of the ICE clones for the first grow. I'll be ordering more seeds so I can have a variety of mother plants by the time harvest rolls around. Concerns Initially I was counting on using the heat from the 400w lamp to heat the room (Its freezing here right now and won't warm up for another month or two). Once I actually built the box and got inside I started getting concerned about potential over heating. We're going to have 1 oscillating fan below the canopy, and 2 fans above the canopy. 1 of the top fans will be blowing upwards on the light and out of the vent while the other one will be slightly below the light blowing on the top of the canopy. Do you guys think this will be enough to keep the 400w HPS from overheating the grow box? (Initial room temperatures are between 68-72 degrees F). The other concern I have is CO2. I have never messed with CO2 boosting before but it is definitely something I want to experiment with in the near future. Do you guys think its something I should just man up and do now, or something I should wait till the second grow, with 1 harvest in this box under my belt? Thanks for everything you guys, this forum has really done a ton for me. I'm actually planning on setting up a WiKi for all of the great stickies on here. I'll have an update on that soon.
