4Lbs dried yeild system builder

I'm the New kid on the block ...first i must say hi to all members and mods, i've been reading up for a few months now and i must say this site is the best read by far keep up the great job. Ok with that said i need help with a newbie setup for a 4Lbs yield. I've seen alot of newbie asking about yeild with there current setup. what i want to do is get you guys info on what i need to make this yeild REALISTIC as a newbie.

how much space ??
how much lights ?? --- size and how may units to cover the space .... i'll be using switchable MH and HPS
A good commercial strian or a rounded strian that can produce what i'm looking for?
which method? Nature , SCROG ,SOG is a NO NO


My idea is to make a protable greenhouse from hollow section aluminum and make it air tight with industrial plastic and add a zipper for doorway. Then line the inside with foylon or maylar attached with velcro.The room will have added CO2 and 2 broan exaust fans the super quite ones, these will be conected to carbon filters. I'll be using top flood and drian with single bucket setup series to a res with added airpumps. Eventually plants will be grown from clones so take that into the calculation. If anyone has any tips or tweaks i'd love to hear them ....the room needs to be SUPER QUITE...and protable and easy to disassemble. I as actually thinking of getting a greenhouse kit but we'll see how that goes. My only concern is the electric bill does anyone have a idea what the average safe zone is for a 3 bedroom. I dont want to rise any flags in the process. if any additional info is needed i'll be happy to provide ....oh and the budget is 2000.

my spelling sucks ass ... i thinks its from all the buds back in high school
thanks

well mate i have a strain just for you, Yeilds up to 700g Indoors.... use a 1000w hps/mh and you will get 700g

THC BOMB

Indoor/outdoor TYPEIndica Sativa Mix
PLANT HEIGHT Short
FLOWERING TIME 8-10 Weeks HARVEST Months 9/10 sept / Oct if outdoor
YIELDHigh up to 700g M2

accully it takes alot of plants to get 4 pounds of marijuana even tho those seeds say 700g i dont think you will get that much, especially you're first time mate, so grow, grow again and you will get experience as you grow

Well everything depends on how much room. money, expirence, time and form of growth you wish to use.Dirt grow inside will take up the most room,followed by ebb and flow setup/hrdopontic and aero ponice the least space.Most high yeild starins will list the high total being with each plant getting 2m2( 2 square meters per plant).You going to have to be able to grow (a) larger quantity or (b) big plants. 4 lbs will take a little of each.I have seen 2 large plants get about that assuming 8-10 feet of plant height is not a problem such as a commercail building or large garage with 14 ft ceielings to give light room.You may want to go with an aero system and keep the final plants 4 ft or under and plant with the mind set of anywhere from 2-14 ozes per plant depending on the strain expirence and supplies you use.4 lbs on a smal setup with little expirence and low budget is a nice dream but won't happen.Now I am familiar with ebb and floww setups and some aero setups.The ebbs I know of by growers with years of practice and refined strains can bulk 10- 15 lbs per 4x 8 ft table which is roughly 16-18 plants.They use 4 1000 watt seitchable ballasts.2 co2 generators tend to work for heavy colas so crop and trim lower stuff and grow tho hrights of 5-6 feet per plant.I have seen aero systems that are 36 site systems that can get 5-10 lbs per harvest using the same 1000 watt light systems usaly 3 lights and a good co2 generator or injector.Either of these setups will do the job but be ready to spead few grand on the setup stuff and electricity.assume on the low side a room of 12 x 12 feet with 9 to 14 feet cielings depending on method.You can grow sog with any techniques but for 4 pounds figues 2-4 oz per plant if your good at this so I'd say minimum 32 full plants going with excellent setup with lights, fans, odor control,growing system,pumps, nutes,co2 injection, humidy care, and everything else.Im going to say for a first time grower 4 lbs will be a lofty goal unless you got the good start up capitol and a good expirenced grower to go to for questions and help.If you ve never done aero or hydro you should do a small few grows to get used to ph, ppm,ec and all hte other crutial measurements you will have to monitor daily.Good luck and post up which meadian you decide on and updates..

Yeah what he wrote a book about haha

Thanks for the input guyz. 420.i figured that would be the case with strian yield figure....they probly use the max figure they could produce...how ever i've heard that THC Bomb is aon the weaker end..... filthyfletch do you have any strians you could recommend?? i was thinging of starting small just a few plant and tweak my setup to master ph, ppm,ec,... however i would just want to construct a big enough space for the 4 lbs grow. I have a 12 x 10 space with 8 ft ceiling. Our budget can be up 3500!!! .... Question though ... would 4 1000watt light be too much for a 3 bedroom place ...meaning would it rise any flags with power comsumption...thats the only problem i have with light setup ...or could i use a mover with 2 1000watt to replicate 4 1000watt???

If it were me, I'd utilize a lightmover, and incorporate some T-5's into my growing area. I also think I'd drop down to 600 watt lights, the depth of penetration that a 1000 watt light would give you, isnt what you need. You need to cover a broad area.
Maybe research sog? That many plants allowed to grow large would be very hard to manage, sog, would be more managable, or scrogging.

4lbs dry. Lets see, that's 16ozs to the pound, so thats 64 ozs. Average yield will be somewhere around 2-4 ozs per plant. So thats somewhere around 16-32 plants. So you're looking at about 24 plants yielding on average about 3 ozs each.

24 plants would require about 4 sq feet each for that kind of yield, so you're looking at an area of about 96 sq feet. That's an area of 12' x 8'. So you're about there on the space requirement.

For that kind of area, you'd be best lighting it with 6 x 400w HPS's. A 400w HPS will light a 4 x 4 foot area well and you have 6 4 x 4' areas. you could do it with 3 x 1000w systems or 4 x 600w systems but it wouldn't be as well lit as 6 x 400w systems.

You could also use 2 x 1000w systems on light movers running down the two 4 foot channels.

And its a good thing you raised your budget. Remember when planning your room you will need room to move around and tend your plants. And all that other stuff.

i would use 2 x 1000w HPS/MH conversion ballast systems... on motorized movers... and then about 2 t-5's on the walls to light the under growth... so it would be pretty pricey... and the money it would raise each month.. 1 1000w system is about 50bucks a month... so 2 is 100 bucks a month.. + 8 t-5's 2 on each wall mm lets say another 150.., to light undergrowth... well it will set u back about 1,300 just for the lights, and then everything else.. but with that much light... i could grow 60plants with high yeild. so in total for the setup i am buying its going to be $3,500 - $4,000 Canadian.... but with 60 plants yeilding 1-3oz. thats triple what u spent... weed is kind of an investment...


In total around $150 extra on ur power bill... so things to do to lower ur normal bill... turn hot water all the way down... leave all lights off, unless needed. unplug appliances that u wont need... this will bring ur power down enough so it will look normal... and i would try and grow a couple tomato's lol to throw people off if they have suspicions... but the power info i have given you is not "OFFICAL" its only a Guesstamit. sorry my spellin is rubbish.... but make due....

I saw the perfect 4lb grow done in an extra bedroom in an apartment, no less.

25 plants, grown from clones in 5 gallon drip buckets with return of solution to the rez. Three, 1000 watt HPS lights on movers. All hot air from inside the room exausted through 6" carbon scrubbers. Co2 used. RO water used. Walls next to the ajoining apartment covered with sound proofing material. A window air conditioner straight into the grow area. Standing in the room, you couldn't hear anything or see any light because the grow area was completly covered by black material with all seams closed with Velcor. Amazing grow ... over 4 lbs per cycle.

Man Id go AK Stoney as hell and good yield.

thanks guyz keep them coming.... I'm going to be using an extra bedroom .... but i wanted to use a 8x8 airtight protable greenhouse within the bedroom to make sure odor is completley controlled. Viredd i like your idea i kinda had something like that in mind. 8x8=64sqft i'm thinking 35 plants 1.5spft each and hope for an average of 2 - 3oz per plant with 3 switchable 1000watt and movers..... and using 2 gallon bucket system. do you think the 2 gallon bucket will be too small?? Godkas could you shed some light on AK47 ... space needed per plant and average yield?? irie

I'd use five gallon buckets if I were you. No use letting the roots get all bound up and limit growth, right? The room I alluded to was done along one wall. There were two rows of buckets, one bucket per row ... 25 buckets in all. I'd say it took up two-thirds of the room length wise and three feet or so out from the wall. The 50 gallon rez was outside the "greenhouse" and sat in the bedroom closet. The RO water came from the bathroon which had its own RO unit sitting on the sink. Everything was overkill as far as the electrical work. I talked with the builder and he said that he always buys the best, and with electrical, heavy duty means no fires. Be sure to lay water proofing material on the floor and up a little bit on the sides of your grow room. A double layer of water proofing just to be safe. No sense in flooding the downstairs neighbors in case of a pump failure, right?

I'll repeat what I read. A 400 watt light , which is what I have, puts out about 42,000 lumens. A 600 watt light , which I wish I had bought, puts out 90,000 lumens. 50% more power consumption 100% more light. The differenc e to the top of the plants is only a couple inches while the 1000 watt has to be farther away. They recommend the 600watt as the most bang for your buck. Wish I'd read that first.

Well I can say for a heavy producer maybe Ak-47 or Ak-48 these seem to always be easy to grow and have heavy buds.Height might be an issue so sticky to inacas or at least a 5-/50 mix as sativas will get tall fast.I have a strain I have never grown but from what I have read and heard is it will produce up to 700 grams its called Sweet purple.I could possible suggest an aero system.I have modified one I built from its original 32 plant set up to a 28 plant setup to increase plant grow room which I think will give me a better yeild then the 32 would have.I have a build guide for it but I asm re writing it to be more specific with more photos of its building.Im contemplating if Im gonna make it free or offer the entire guide as a small fee based pdf file maybe $5 for the enite thing which will have step by step directions, pictures, supply parts list and list of places I got the parts.Whole setup with the pump I got is right under $200 complete with res.I am also contemplating making a mod version I would prefab and sell for about $350 plus actual shipping.I dont know Im still thinking this one out and may just stick to the build guide or make smaller prefab units for like 6, 12, plant systems.We will see

Viredd did he flood from the top of the net basket and does he drian the buckets completly or does he leave a few inches of nut in the bottom ??? I've been reading up on the light setup .........i think i might just go with four 600watt with digital ballast and aircooled refectors....from what i've been reading if i use four 600watt in a 8x8 space i should be getting about 5000 lumens per sq ft....and i'll get a better coverage and save on power consumption.....i'll just have to keep it closer to tha plants .... but either way four 600watt should be good enough right?? Filthy ... i'm trying to take the best from all systems and make something workable..... i was thinking of using a large airpump and pump air directly into the buckets instead of just airating the res. i'm in jamaica right now so i'm just putting some ideas together but i'll be sure to keep you guys all posted on my setup when i get started.

The buckets were actually one bucket inside another with a top drip system. The solution was pumped out of the bottom bucket and returned to the rez. The four 600s sound like a good way to go too. I use a 600 hps myself.
