Cab Scrog Grow using DWC

Here are some photos of my recently constructed cabinet setup, using DWC. Current crop is Aurora Indica. I have incorporated an automatic water feed to provide make up water while I'm away on business trips. The 5 gallon reservoir (bucket) will keep the water level where I need it for at least a week. Also note the way I plumbed in the cab air intakes, connecting the 1 1/2" PVC into the reservoir tub, which causes the cab intake air to flow across the top of the solution in the reservoir, and out thru the two PVC elbows at the front of the reservoir. The evaporative effects keep the reservoir solution temps below 70F even when the ambient exceeds 90F. I have not seen any sign of algae growth in the reservoir when using this arrangement. Cab out flow is provided by a standard 120 cfm in line fan/carbon filter. Solution aeration is provided by a double diaphragm fish tank pump feeding two 48" flex tube air diffusers coiled in the bottom of the tub. Note the air lines running inside the SCROG screen support frame down into the bottom of the tub. Root growth has been very strong. You can't give roots too much air when they are submerged in a solution. Looking forward to harvesting some killer AI!

nice . any complications when changing rez

PVC ventilation fittings are slip fit only, and remove easily to allow rez removal and changing. Bubbler air tubes separate at the black fittings. Water feed hose separates at float valve fitting. I will be adding a garden hose quick connect fitting soon. I siphon out rez, and then remove it from the cab. No sweat!

hophead55 - That's a very good looking set up you have. Very nicely done!!! :thumbsup:

I just finished my first ScrOG - four plants filled a 16 sq. ft. screen. You might want to reconsider the number of plants you have there. Eight plants seems kind of excessive for that small area. -jmo-

Ill prob lose half the plants when I start 12/12 and sex them.;)

Ah - I see! I didn't even think of seeds - I have clones stuck in my brain.

On my next scrog, I'm going to use two screens. The first screen is for training/tying the plants; the second screen, about 12" above the first, is to support the buds.

PC :smokin:

I'm not using the screen this time, as it will be too hard to separate males/females with them tied and woven into the screen. I have started 12/12, and will do the best I can to support the rather lanky remaining females until maturity. Of course I will take cuttings from the most hardy plant to provide clones for my next grow, which will allow me to use the screen for the next batch.

I'm looking forward to updates as I am just starting a SCROG and although my plants are quiet a bit ahead, it will be fun to see what happens in your grow. I will be following along for sure. If you have a chance, stop by and check out my grow log (sig below) - I am seeking comments and input.

Very inventive. Real nice.

Here is a pic taken this week @ 2nd week of flower. The males are history, and I am using LST to keep the remaining three females as low in height as possible. Lights have been switched from MH to HPS for 12/12, easy to do with my Sunleaves mini hood, which has a switchable ballast.:cool:

Looking good, how long is the flowering period expected for those AIs? Can you tell us a bit more about the lighting unit? I bet those babies will be tasty here is a couple of months...

The light almost looks like it's liquid cooled or has the ballast attached.

I expect the AI ladies to finish in about 4 more weeks. The light is a 250 watt Sunleaves mini, with a switchable MH/HPS ballast. I have it connected to the outflow fan via metal hose. The fan is on a rheostat, as I use fan speed to control interior temps. I think a 400w lamp system would give better growing conditions, even in such a small cabinet. I'll post some more photos at harvest time.:yippee:

Cool. I'll be here.

Hey is that a Shallow DWC (SWC) as seen on the old OG? Damn cool, just looking to find out if it is the same or a modification/spin-off. And also how productive it is for ya. Can't wait to see your harvest.
