Hey Storm... good idea on the thread... well I've built this ridiculous system and am waiting to put some cuttings into it... I've done more research than anything else and this is what I 'planned' on doing...

Flood frequency and duration in LIGHT: 15 mins on... 15 mins off

Flood frequency and duration DARK: 15 mins on... 15 mins off

(I don't think there should be any difference in light and dark unless they are weeping at night from overwatering, which I think is my current problem with my other drip system)

Grow medium: Expanded Clay Pebbles (Hydroton)

HYdroponic system: Ebb & Flow

Wattage of light: 400w Switchable MH/HPS

grow pot size: 4'' PVC cut and capped to about 8" deep

reservoir size in gallons: 24 gallons

number of plants: 11 plants

Veg and flower time: 30 veg days / around 5 weeks for flowering
(Both depends)

Strain type.....max yielder? nute-burn sensitive? Some shwag-shit, N/A, and yes... sensitive to nute and light... very sensitive

Extra air-circulation to root zone? fans directed at root zone? Fan blowing above canopy, fan blowing below canopy... fans directed at root zone?

Co2 usage? No


Here are some earlier pics of the setup itself... it will be connected to a 315 gph pump that usually fills all pots evenly after 2 mins... it drains in about 1 min and keeps a small (1") amount of water in each pot even after drained which I think is beneficial. I built this system and the stand to fit in my homemade greenhouse, everything fits perfectly. Hopefully this thread brings out some great ideas and most likely will make some changes... hope this helps... sorry to not have tried it yet... but soon!
Absolut Chronic Reviewed by Absolut Chronic on . Hydro ebb/flow flood schedule opinions/theories Ok Ok, there are many factors that affect the best flood and drain schedule. Some set-ups would require more frequent floods than others. Some strains may benefit from more or less frequent floods. Root space, aeration and air-flow, use of C02, strength of nutes, grow medium type, these are all things that determine best flood schedule. I want everyone to give their opinion on this. Tell us YOUR success you're having, your grow medium, your flood schedule dark and light. I use Hydroton, Rating: 5
