I have these already 6" x 7" tall.. side drain and a net style bottom.. will these work 20 per 4x8?? two kw's per 4x8 .. 15" starts hopeing for 2 ounces a plant.? or do i need a bigger pot? big pots not necessary here right?

The pots you have look perfect,i have some like those myself,we have so many pots we couldnt get all the same style to start with,we have all one model now for simplicity sake but thats it,i found no pot to be better or worse than others as far as growth,with the lid in place roots will thrive outside the pot so larger pots dont really help or hinder growth.

Depending on the obvious issues pulling 2 ounces per plant will be an easy mark,i have pulled 5 before off a single plant with my sour d strain,its a huge producer,keep in mind i dont weigh crappy lil buds or fluff,buds that are not top shelf quality are given away & or turned into hash,popcorn also dont get weighed,just be sure to let your plants veg to atleast a foot,being that your restrained by plant count ya might be better off letting them veg past a foot a bit,a dense canopy is where huge yeilds are at.

As for getting the perpetual aspect of the grow going here is what happened to us,we grow collectively so we have 8 tables,we set them up for a harvest once a week using 8 tables filled with 60 day strains.

Having a harvest every week quickly became our sore toe,i have a partner & both of us hated being tied to the weekly harvest,its every week no matter what life threw at us we had the harvest.

We switched out cycles with weekly harvests for a harvest once a month,this way we only loose one weekend a month,plus if the harvest is to much for us to trim we bring in help,which is allways the case.

Ok back to the table,if you know your strain well & if your confident no problems will arise im sure using one table with multiple harvests can be done,i just prefer to plan out where if problems arise i have the best chance of correcting the problem,with as little stress on the plants possible, as well as the least possible work for myself,running full tables is best for us.

Aside from challenges with nutrients & plant def's there is another challenge in running a table with different harvest times,this problem is lighting,using multiple lights on a single table you want each light to compliment the other lights light throw to help cover the table with proper light,if you use 2 lights the spacing will require that both lights use each others light throw in the center of the table,by itself a single light will have a soft spot at center table,the 2nd lights coverage helps strengthen the light at center table.

If you have plants being inserted in the table at different times you will not have an even canopy,the light over the fresh plants needs to be lower than the light over the older plants,this leaves the higher lights thrown light to be wasted from bouncing off the top or side of the lower lights reflector,also the lower light over the newer plants will be spreading its light over a smaller area leaving center table disadvantaged.

I have a bunch of 1,000 watters we used in the begining using 2 of the 1,000's per table,we have better coverage using 3 600's per table so we switched out for all 600's,we also have tighter nuggs & no issues keeping a nice canopy.

Why not just set up each table a month apart with 25 plants per table,this way you never have to worry about the issues with seperate plant times as well as lighting issues,you never have to move plants in & out either.

I saw only negatives in having tables with different harvest dates & only plus'es to running a solid table.

thats what im gonna do.. ill start cleaning and shopping at home depot.. i have the youngsters already gettin there vedge on. ill keep you posted i promise u will be hearing from me.. thanks pan youve been a great help. ps.. i got a chuncky soud d (8 weeks) chernobyl and bubblegum from the early 90's that ill b using.. can wait. im happy to be done with al's method but im sure ill be back one day.

Cool & your welcome.

I too started out following al but his method isnt real easy to adopt & isnt user friendly,the theory is sound but flawed, i modified it to fit my abilities.

Im not shittin you about the ease of this system,once its up & running you have nothing to do except change the rez every 2 weeks,the lack of medium & constant floods make it the easiest system for flood & drain,the 24 to 36 floods a day make sure the plants are feasting & the lack of medium keeps the roots healthy,plus no mildew,something al fought with constantly.

I would like to hear how it turns out.

i had to start applying eagle 20 in my veg room and i have all the band aids.. never dug the sulphur burner much though. But ill be stoked when that shit stops poppin up on me.. i have fresh pumps so no worries there.. The new CAP ebbngro monster has the bomb pumps for 4x8's and they only cost me 25 bucks each. i had to clean salt and leach pots with clearex once a month with sog letting the plants clean them is gonna save time and worry also. Pan what nutes are you using and at what ppms per week.. i think i have enough to get started, im gonna push to have a converted table filled in about a week.

I use the general hydroponics line,flora gro,flora micro & flora bloom,in heavy bud i use botanicare hydroplex as a bloom booster,the hydroplex has cal mag as well as other micro nutes,i stopped using gh's bloom booster ( liquid cool bloom ) in favor of the hydroplex & prefer it,since using it i dont need to use cal mag anymore,durring the portion of the grow where were not using hydroplex we use epsom salt.

My main strains are blue widdow & sour d,i run both these at nearly the same levels,in bud ppm 's are at 1,000 & in heavy bud it goes up to 1,100 but never higher,the blue widdow gets some extra nitro in bud.

I also run 8 other strains were phasing out in favor of these 2 strains,if your sour d is the same strain as mine anything over 1,100 will start to burn.

We get 2 liter pop bottle colas on the sour d & extreme resin,i'd love to see what that strain would do in a greenhouse fully attended.

I have no pictues yet, so this maybe a pointless post. I finished my first table.. complete with 20 cut outs. i used the peel and stick velcro with the neon green .37 spring clamps that you recomended pan. Its trampoline tight just waiting on the babies to reach the 12-15 inch mark under the t5 in the veg room. cant wait.. looks like thurs day will be day one. ill try to get some pics up.

Cool,would like to see it.

View attachment 1773522Pan i finally got a pic.. ah .. the 10 on the right started on the 25 the ones on the left started bloomin on the first. My chernobyl is acting very wierd but the juicy fruit and the super lemon haze is lovin life. i think im gonna drill more holes in the base of the pots and i have small pooling in the middle 20% of the time. so far so good. hows your garden doin' pan?

Lookin good,the top of your table looks nearly exactly like mine.

Hope ya figure out whats going on why the chernobyl is acting up.

Im taking a break from the grow,my partner is much younger than me so he's got my back while im gone,i hurt my back again a few days ago & my left leg is like a limp noodle,can barely use it from the pain,i have another surgery on my spine comming up & i cant wait to get this fukin disc replaced,its killing me.

Only good thing is i can get real fucked up,doctors orders,sitting here with a couple 75 mg morphine patches glued to me & smokin on some sativa hash to mellow out the morphine.

Its the perfect time for me to learn the moderator user cp functions,theres lotsa buttons & options that the normal user cant see so im trying to learn them all while im laid up.

Im tryin hard not to make any mistakes with the moderator functions,im in no mood to argue like some other new mods,arguing while in pain dont even sound cool.

Keep up the good work,im dying to see if this method works as well for you as it has for me,im betting your days of using sulfur are over,lets hope.

Its working good so far. im due to set up the other one tonight. im still needing another 150g rubbermaid so i can make each 4 x 8 independant. which i know is key. For some reason im losing my fight with clones, probably the worst couple of months cloning in the last 10 years for me. I think nothing pisses me off more then seeing dryed up clones via als method in rw.. i think im gonna swith to the rooter plugs and dome and just be patient. idk what method are you using pan?. ill try to keep more updates now that i have a way to put up some pics.. maybe start a thread since im within my numbers. taker' easy pan, if you start turning red add another patch, smoke another bowl.

hey pan, yep im liking your setup.. just a couple of questions.. the panda cover is nice and tight and holes for your 5" net pots are tight, so is the panda keeping the pots raised off the bottom?, also how high do you flood the pots?, any problems with root blockages?..and what are the bits of tubing for? nice cheap effective setup..kudos

Hey pan i have missed your pics and would like to see your setup ass it similiar to mine from what i read.

This thread is old as hell, and I'm not sure the OP is aware it's been brought back to life, but I see a few of you posting in it so I'll ask my question anyway...Why not just go with DIY aeroponic, and cut out any medium all together...?

From what i understand panhead was able to do just that, with ebb and flow?
thread might be old but we can breath some life into it

Hey bud.

Fastening the plastic is easy,its keeping it from sagging thats a bitch,we ended up making supports for the plastic so its like a toneau cover for a truck.

We used pvc plumbing pipe & cut peices to fit on the ledge at the top of the table,we used 5 pcs of pvc per table,then lay the plastic loosley over the table & roughly square up the corners,then clamp one corner of the table on a short side & go to the other end & pull plastic tight & clamp,then go to the other side in the middle of the table & pull the plastic tight & clamp,then work around the table giving the plastic a tug tightening it up & clamping it down,we use approx 20 clamps per table,the pvc pipe & the clamps keep it tight & flat for months with rigorous use on the table.

Can anyone help me understand how he used pvc plumbing pipe for fastening down the panda?

i think he was using it as a frame type system for keeping it tight.

i know this is old but i would love to see a couple pics of this as well. are the net pots suspended or just sitting on the bottom of the tray?

i did this style grow also.. it works really well.. its basically a nft type set up, but instead of drip, panhead flooded the table once every hour during lights on? if i remember correctly.. If your plants are too small the root mass wont really take off but if you get the plant established in its little pot with some good roots hanging out, they will take off and do very well.

tavitude has a grow with shallow rubbermaid tub that is very close to the same. similar but i dont know his flood cycles.. but you want a huge bare root mass in the flood tables

the panda is held on by cheap clips from home depot. the root zone needs to be light tight. the constant flooding keeps the moisture up in the covered flood tables and the roots fill the tables up. fun to watch the root mass build up.
