Ok. So I'm just being curious here, but if I wanted to do a perpetual harvest every 2 weeks, could I do it with just one 4x4 table and one 400hps cooltube in the flowering room? Assuming of course that I'm using organic nutrients and therefore a flush wouldn't be necessary.

no thats impossible, period. and when using organic nutes you still have to flush plants! organics have salts to, and flushing is to rid teh soil of salt buildup.
a prepetual grow every 2 weeks would take a minimum of 6 plants in flowering @ all times, that takes up all of the space + probably more depending on how long they were veged for. you need a way to get only females, @ least 3 every 2 weeks so that you can have sucessful, strong plants (kill the 2 weak ones, keep the strong one) this means you have to clone or have a place to buy clones..... it is possible with feminized seeds but its EXTREMELY expensive.
personaly i think the smallest a perpetual grow can be is 1x 600 watt HPS over 1x 6x6 table for flowering and 1 CFL clone box for a harvest every 2 weeks. you can do it smaller but you will be harvesting less, more like once/month.

So what if I got 4 2x2 ebb and flo tables under a 400w cooltube? Do you think I still couldn't do it?

put a plastic bin up on something inside the flood table. Run your overflow and feed lines right through the bottom of the flood tray into the bin, and use a second smaller res with its own pump for your flush feed. Independent system within your existing flood and if you put a bung in the side or a stopper of some kind you can use it for your clones to sit in and establish roots before you put them in the 'deep end' 
Hmm. So if I had one 4x4 table, with a bin inside that has its own pump and reservoir then I could do it? My veg room is separate.put a plastic bin up on something inside the flood table.

you would need multiple flowering rooms or a large room with plants staggering in flowering time, along with a mother, veg, and clone area to achieve this. I don't know why you would want to harvest that often. There is a lot of work that goes into a perpetual grow. A bi monthly crop out is enough to handle and keep a steady supply while still maintaining a nice clean grow. Every two weeks would be crazy for one person.

its the easiest thing I can think of, kindof permanent tho. Probably be smarter to set it next to your flood table and offset your light when you final flush.

if you got this stuff you could do a small perpetual grow.
4 2x2 Ebb and Flow tables (or bubble buckets, a DWC setup)
1 400 (600 is better...) watt HPS light
1 150 watt MH or CFL setup
1 grow tent.
Put the CFL or MH setup inside the grow tent and use it to clone from an amazing female. Put the HPS inside the flowering room. put those clones into flowering after 1 week of root growth and 2-3 weeks of veg. Set up 1 Tray of clones (1-2 clones) every 2 weeks and after 8 weeks you should have your first harvest.
. i smoke an OZ a week and suply an OZ/week to another friend who cant grow. it goes by faster than you would think.....

you dont need multiple flowering rooms to stagger growth. i harvest 5 plants every 2 weeks and i only have one room and one tent

if you read my post you would see that i didn't say you need multiple flowering rooms to stagger growth. I said multiple flower rooms OR a large room with plants in staggering flower times. If you harvest every two weeks you're trimming, curing, and disposing of waste non stop. Unless you have a small room growing very few plants such as you are doing.if you got this stuff you could do a small perpetual grow.

So I guess Ill have to stick to harvesting once a month. Currently, I have a 3 gallon 15 site dwc cloner, a 10 gallon 8 site dwc tub, 2 3 gallon dwc buckets for mothers all in a 2x4 tent. Its all under 2 180 watt Lighthouse blackstar LEDs. In my 4x4 tent all I've got a is a 6 site rdwc that uses 5 gallon buckets. I plan on splitting the system to two 3 bucket rdwc systems. So in the end I harvest 3 plants every month.There's a 400 watt cooltube hpsin there.
Ill take 15 clones and root them for 2 weeks. Then Ill take the best 8 and veg them for 8 weeks. In that time ill be fimming them after they show the 3rd set of leaves. Usually in the first week of veg. In the second or third Week ill be super cropping the main stem and any other off shoots. 2 weeks after putting the 8 in for veg I'll be taking another 15 clones. After the 8 have vegged for 4 weeks,ill pick the best 3 and flower them.

Maybe if seed was no issue ,and you could run 12/12 from seed and plant a seed every 2 weeks. If the 4x4 would hold the amount of plants you would end up with witch would vary on strain due to time of finish.
What kind of results are you seeing from that setup? How tall are your plants getting?

actualy it was me who said it was impossible, and thats for a reason. a Hortilux Super 400 watt HPS light produces 55,000 Lumens. a simple flowering marijuana plant needs around 12,000 lumens for proper development...... that means you can grow 4 plants PROPERLY under that light. you CAN do it, and you can grow some prighty shitty pot. were here to talk about growing Quality marijuana, and its IMPOSSIBLE to grow Quality marijuana from stuffing way to many plants under a single underpowered light.
simple answer for you, it is impossible without MORE LIGHT.
oh and P.S. a 600 watt light produces over 75,000 Lumens...... thats around the ammount needed for 6 plants, and therefor a good perpetual grow...... like i said earlier.
i know, i was mearly furthering the evidence for single room operations. i didn't mean to offend you your one of the people on this post who's actualy helping, no harm intended.

I think your misunderstanding what a perpetual grow is. It has nothing to do with what type of light your are using or what size your table is if you even have one. I have seen perpetual grows that only utilize t5 set ups. To have a perpetual harvest you need only seperate flower, veg, and clone areas, so that when you crop out, you have plant stock to move in the flower room right after and so on. It also does not matter how many plants you have to make it perpetual. You could have one mother that you remove one or more cuttings from each cycle. I hope this helps

what you dont understand is lumens per square foot. u need so many lumens to grow so many plants. for a perpetual setup you NEED to grow MANY plants. PERIOD.
harvesting every 2 weeks, lets do some math: it takes 2-3 weeks of veg + 8 weeks of flowering to produce 1OZ/plant
Day1week1: start 3 clones to guarentee sucess.
Day1week2: start 3 more clones
Day1week3: start 3 more clones
Day2week3: move first clone to flower
Day1week4: start 3 more clones
Day2week4 move second plant to flower.
by this point an individual taking the strongest of 3 clones and killing the weak 2 would have 7 plants, to continue this cycle untill week 11 (8 weeks flower + 3 weeks clone) would mean the individual has 11-12 plants and starts harvesting 1 plant per week.
ok now we get to the real math now that we have an equation.
9 plants flowering x 5,500 Lumens per plant = 49,500 Lumens to properly flower these plants.
4 plants in veg (one mother, 3 clones 4,500 lumens for the mother, and 1,000 per clone) = 8,000 lumens.
now remember his question
can it be done with ONE 400 WATT HPS?? No it can not be done with 1 400 watt HPS. for this reason
55,000 Lumens (the BEST 400 watt on the market BTW..) is only enough to sustain the flowerin room. he still needs to support the clone room.
this isn;t about tables or BS. i use organic nutes, grown in SOIL, watered by hand for my grow. this is about the lumens produced. and the simple answer is get another light.

wow you really read alot about growing.
just because a plants under a light doesn't mean the light magically produces 44k lumens instead of 55k.
and in veg, the light needed for even massive plants is minimal. Its the distance from the light that matters, so you move your larger plants right under the light and your smaller plants further away. A 400w is fine for a 4x4 foot grow area, just elevate the little ladies up above the canopy of the big ladies

the only part in this that makes sence is thta part " in veg, the light needed for even massive plants is minimal." the Maximum Lumen Intake duering Veg is 4,500 Lumens. you'll see i meantioned that.wow you really read alot about growing.

and if you want to tell me this is just about reading im going to my Big ass outdoor today and coming back with picks of 119 Indica. i know alot about growing because i goto UBC for botanical studies, the main university in north american when it comes to cannabis research. they literally teach classes on Marijuana here, and if you pass certain courses your allowed to grow "for reaserch purposes".
oh and "just elevate the little ladies up above the canopy of the big ladies" have you ever tried to clone under 12/12? i guess not because 12/12 tells the plant its ready to produce flowers, not produce roots.... you wouls know this if you have ever tried it.

that's pretty awesome and exactly what I said. You've read alot about growing, but as far as applications for indoor it sounds like you haven't done many.
why would he have clones in the flower room if he has a separate veg room?
I meant the smaller plants ready to flower need to be put on top of something so they aren't being shadowed by the already flowering plants, then when he harvests he can just relocate his tallest to a spot under the light.
If he's setting up a perp grow, the lights only going to move up when the tallest plants get too close. The plants themselves would be on buckets or boxes or books or shelves or whatever and be moved down as they grow closer to the light.
I never said you didn't know how to grow man, I just said you've read alot about it.
