I have a great grow going into flowering now. AK-48 & PowerSkunk. It started out as a true aeroponics setup (no nutrient solution to dangle roots in) and is now migrated to a full on DWC setup. I will post pics soon but here are the details:
25 gallon Rubbermaid Roughneck Tote
4 x 5 inch net pots (placed far into the corners of lid to allow each plant ample light space)
600 watt Lumatek digi ballast (awesome unit) & a EYE Hortilux Super HPS Light
General Hydroponics 3 part Nutrient system (I like to keep it simple now), with a little Northern Lights 'Fat Flower' durnig flowering
An air pump that puts out enough air for a 100 gallaon aquarium (2 outputs) with 2 long air stones
Another 30 gallon air pump that feeds it's air line directly into a submerged aquarium Power Head (Power Sweep 214).
I have found that the Power Head idea really helps recirculate the nutrient solution as well as add way more oxygen to the water - you can never have too much oxygen rich water... the more the better. I fill the resevoir to a little less than half of it's height (roughly around 13 gallons). I dont have any problems maintaining Ph, I rarely have the need to adjust ,but still check everyday (I keep around 5.8 - 60). I highly suggest getting one of these power heads to significantly add more O2 to your solution. Your water will scream Boo-Yaaakaa!! once added.
Nutes, I use are your highly effective and fully customizable General Hydroponics "Flora" series. I use this stuff called Pot O'Gold, which has electrolytes and supposedly changes the chemical structure of the water - making it highly available for uptake. And lastly, I use Zone from Dutch Master to put out a pre-emptive strike on any root problems that might be lurking. Oh, almost forgot the Northern Lights 'Fat Flower' additive during flowering.
All in all, I am really liking the DWC method and the plants are responding alot more to this system than they were in the Aeroponics system. The plants were in the same exact Rubbermaid Tote durnig Aeroponics, except I just changed up the plumbing to DWC now.
Cool, I hope this info had some significant content for some of you - Peace - NYK
