prepitural SOG ebb n flow, help?

[cork144]

so after reading drgreenbuds and all the other great SOG grows thathave spawnd off of it, ive decided to do a prepitural SOG.

I want to use ebb n flow, this proves to have afew problems such as i need 3 different resivours and 3 different tables for the 3 different nuting programmes.

i intend to have 9 generations of clones in at once, 2 or 3 put in a week topping to a max of 27 plants, but for the last 2 weeks i need a flush table, for mid flower i need a full nute mix, and for the just put in clones, well they need a weaker nute mix.

So basicly what i was thinking was having my flood tables and simply leave them bare, by using 2l coca cola bottles cut down to 600mil (bout 21oz) fill them with hydroton make lots of holes in the bottle and put the rockwool cube with the clone in ontop. Does anybody actully think this would work?

ive decided on ebb n flow because once ive got the swing of keeping ph and ppm in check, its quite low maintance appart from the topping up of the res.

Im going to be using 6 36watt PL-Ls all warm white and 4 20watt cfls also warm white,is 296 watts enough to sustain 27 plants? im going to be growing white widow and maybe have blueberry in there also.

Dimensions are going to be the same as my current cab appart from the height because im not sure how tall my cab should be yet.

Width 90cm, Depth 50cm, Height 65cm (these are dimensions of the actual grow area, the cab will be taller for res space)

Fill the beds with hydroton and put the cubes straight in it. They'll love it.

yes but this doesnt allow me to check on the plants and move them about in the cycle, i need to be able to move clones from weak to strong then eventually to the flush, wouldnt be able to achive this in a single bed hydroton.

How much do you expect the roots to grow outside of your 21oz bottles? With 6x6x6" rockwool blocks and panda poly on top of the table, my roots become a giant "mat" as roots grow into one another. It would be nearly impossible to untangle and move plants around after about 15 days of veg for me, let alone right before a flush.

my plants will have 0 veg time, asoon as they root thats it theyre in for 12/12, roots will be trimmed to keep them contained within the bottles.

Sounds like you got your plan dialed... 27 plants in 21 oz containers, zero veg, divided between multiple tables and reservoirs under 300watts. Ebb n' Flo is undeniably fool proof and low maintenance, but I am thinking there might be a more efficient method with the numbers you are trying to run. If it makes a difference this is the route that I would take for a small level CFL perpetual grow.

I would cut a coco mat to the size of your tables, the one shown below is 4x8 for about $25.00



I would dedicate each "generation" for perpetual into its own mat,once your clones show roots, place them on coco allowing the roots to find a home inside, you can than lift your whole mat and transfer "generations" between tables in one motion with no trimming etc.

I have found true in the past that root mass is directly related to bud production.

yea i also want it to look top notch from the outside also, remolding my room and my grow cabs gotta blend in.

basicly im just after maybe an oz per week, it could be dialed into a more efficiant grow cab, but if this will be adique, then let it be.

i am open to ideas but im gonna test what ive planned then if i dont like it, ill change it, i like the idea of being able to use the bottles in there, thatway i can move the plants about to make sure other clones arnt getting their light blocked.

also found 30Ltr tubs on ebay i can use as resivours and they fit perfectly for my dimensions, just need to think of what to use as the flood tables since i have to get 3 into 90cm width 50cm dept.

oh and ventalation and odour controll willbe a DIY carbon filter inside my cab directly connected to a 150MM fan with about 10cm of ducting to the outside of the cab, duting is so i can suspend the fan so it doesnt cause vibration on the wood, do you think this 1 fan would be enough?

if not ill do 2 fans with 2 carbon filters, passive intakes btw.

GotDRO?, would there be a nice ballance of nutes for my new cuttings and the main flowering plants? so that i could have a small flush res and flood table.

 

[GotDRO?]

Balance..?.... as in the new cuttings not getting shocked by mid flower strength nutes, and the flowering plants having sufficient nutes for proper budding?
Its a possibility that you could dial in that sweet-spot PPM in your res so that plants at every stage are pleased, but you will never achieve the "ideal" level that plants will thrive to potential in terms of yield and potency.
Another issue you will run into is introducing new strains to the perpetual. A sativa cutting with mid-flower indica strength nutes will fry.

 

[cork144]

any advice on the setup then? i know i need space for maybe 6 plants for the flush table, need to know how long my new clones should be in for in the weak nute table and then i canwork out the space for the stronger nute table.

Plan on your main table being at least twice the size of your other two (early flower and flush) the main table should house the plants for 4 weeks total, meaning the main table will always have 2 generations feeding off the same PPM solution...

EVERY 2 WEEKS,I would shoot for 6 cuts leaving your cloner/dome, 6 cuts shift into your early flower table, 6 cuts get bumped into your main table (for a total of 12), 6 cuts move into flush and 6 cuts meet the scissors. This would require three separate tables/reservoirs. Since you shoot for zero veg, I would personally feed a high Nitrogen diet for 12-14 days during "early flower" (veg nutes) before sending them towards main table with traditional flower nute ratio.
