Things to Know About Lighting

Says who? Mercury Vapor lights were originally used in greenhouses. They're just horrible for POT.

For varied herbs and spices, a MV bulb is just fine.

Who's talking herbs and spices, were talking weed like you state. MV suck compared to almost every bulb on the market.
Put that plant under cfls as they have a better spectrum and are more efficient. The only good MV bulb is a free one, even then I would not use one.

Its not all about photosynthetic power.. Different parts of the spectrum stimulate different growth patterns.. Same argument you made against MV could be made against MH since HPS exists.. But hardcore growers choose to use MH during vegging atleast..

I'd actually like to try it during early vegging.. If they can facilitate extremely short internode length, I'd be willing to take the hit on PAR watts..

Thats what i was thinking. Naturally MV lights are dark blue usually which is perect for prevegging and germinating, especially effective during this time period of growth. Use metal Hylide for vegetative stage and HPS for flowering, the best light routine possible if you have the right bulbs.

The temp goes like this; 5500k+ during germ/prevegg, 3500-5000k during prevegg/vegetative, and 2200k-3000k during preflowering and flowering. Anybody who reads this needs to try it on a single plant and compare it with a flowered plant with this routine and compare it with what you would usually have for your lighting and you will absolutely see a difference.

Great tips!
I am in the planning stage so, I'm looking at my options. I am looking at a self contained grow cabinet 6' w 2'd and 6' h VS a grow tent 10'w, 5' d, and 6' h.
I like the cabinet because the accessories are built in it's incognito and it locks. A no brainier. But, I don't know what kind of yield it can produce (every 60 days). I would like to produce 1 to 2 pounds of bud every 60 days or so.
I have a space in the back of the garage to put the tent. it's not as incognito and I have to buy all the internal and exterior accessories. But it is a lot larger and will get me where I want to go.
I guess my question is how much bud can I produce in a grow cabinet?

The only goal you should be setting at this point is to learn how to grow plants as well as they can be grown.. If you get a yield that makes you happy on your first grow then congrats, but no reputable grower on this forum will tell you how much to expect.. Its possible to hit your goal in either cabinet, not easy in the smaller one, but possible.. Seriously don't expect that until you know the ropes..
6' height can disappear REALLY fast.. Especially on a first grow.. You'll need to pre-empt that, and that means focusing on height control fairly early..

If you set your grow box perfectly before growing than expect higher yeilds. 6 feet of space is enough for nearly any plant you will grow and there are ways to grow your plants shorter and really flippin bushy and produce a shit load of bud with the right lighting, temperature, humidity, CO2, nutrients etc. With 2 or 3 plants you can possibly get up 3 or 4 pounds of bud matter. Expect that to be the maximum though, You can produce more but only proffessional growers do it 'right'. Of coarse it ALL Depends on the strain in the beginning. Get 3 AK47 plants and you can produce up to 3lbs every 80 days. Look for rooting hormones as well. I dont use them but ive seen it be used and omg its amazing.

I'm calling shinanegens.. A pound/plant indoors in 80 days ain't gonna happen no matter how good you are, or how sweet your setup is.. To pull that off you'd need to veg for a long time, and in the area you intend to flower, because you'd need to grow them entwined in a scrog to stand any chance..
With 2 grow rooms you 'might' be able to pull it off if you vegged one room while the other flowered.. You're still far better off with more small plants..
And its true that 6' is enough to grow any plant if you know how to control it from day one.. But things can get out of hand REALLY fast if you aren't on the ball.. Figure 18" for root systems, 8" for the height of the actual light/reflector, 12" for space between tops & bulb.. Thats a minimum 3'+ consumed.. Some plants will get taller than that if they're vegged for 5 days.. You gotta know your plants.. Even experienced growers need to learn the nuances of new genetics as far as training solutions go.. Thats why permanent mother plants are so ideal.. After a few crops of the exact same clones you can peg the nuances down to a science..

Edit: To clarify on the space disappearing, some plants still want to stretch ALOT after you flip them to 12/12, and at that point you're between a rock and a hard place because topping/chopping and high stress in general after the flip will devastate yield..

No you dont man, you have no clue do you? My last set up I had was a 6 x 3.5 x 3.5 with the perfect set up with a 600watt hps, 500 cfm intake and exhaust, humidifier and a 10 liter displacement CO2 canister with just regular nutrients and superphosphate and out of my 3 ak47s combined gave me in DRY weight 3.25 pounds of BUD not leaf, bud. The key to harvesting every 80 days that much weed is by having separate grow chambers, one for germinating and one for vegging, so there is always a plant germing always a plant vegging and always a plant flowering. By the time your flowering plants are done then your vegging plants should be ready to be put in the flower oven and the same with germing to vegging. I have already figured out how to easily produce 5 pounds every 80 days about(rough estimate could be less or more time). Im not trying to sound like an ass by arguing but im just trying to say that yes it is possible, and you should not just go doubting watever a person has to say im right on this one; because I have experienced my plants capabilites and obviously you have not.

It is true that the plants will stretch a lot while flowering, you must have and out look at whats going to happen so you do not burn or starve your plants of fresh air and CO2.

i have definatly gotten a pound in 80 days off one plant easy you dnt need a super big room if you grow areo from seed and veg 20 days than flower for 60 with the right strain its quite simple.... not the best use of horizantal lighting but it can be done... areo grows quick... im back in soil now

Like I said, with 2 rooms its perhaps doable, but you're then looking at half that yield per room per period.. Only thing I can think to say of your claim, is I'd probably be pretty miffed by what you consider 'DRY'.. Especially since you're talking about 'leaf free' AK47..
And as for tusseltussel, I'm torn.. I don't think 20 days vegging can pull that off with any plants I've seen, and I've never seen a respectable plant actually finish 60 days after 12/12.. Are there many pics on here of single 1lb indoor yielders?? I do agree that it isn't the best use of horizontal lighting though..

What is the best distance to keep the light from the tops of your plants.

It really depends on the ventilation, genetics and light type.. Any closer than 12" with a 400W you'll probably regret.. I've never used 1kW's.. Don't shock them! Let them adjust to brighter light slowly.. Keep an eye on leaf edges.. If you lower them slowly enough then its harmless to let them tell you when its too close as long as you're vigilant..

Problem is that Ferrets are illegal in California. I think it is because they are so smart they will trick their trendy owners (like all the people who bought those bug-eyed looking Chihuahuas that have that complex and think they are 12 feet tall like Napoleon Bonaparte) and get free and start a rodent revolution and eat all the "goddamn chickens". At least the chickens can spin around in their cages and fight back a little, but if the ferret has access to ACME (like Wile E. Coyote) those chickens are done for, quick-like...

If ferrets we legal in California there'd be ferrets running down the powerlines, it'd be like their freeway once they scared the crows away (sound like another cartoon). We'd all have to wear hats and carry wiffle-bats... lol

You are very strange. Obviously you havent seen or smoked true Serious AK47. These plants yeild between 350 to 500 grams of dry weight bud, info given by the breeder himself. Now if you calculate that into ounces you get between 12.5oz---17.85oz. Now correct me if im wrong but... 16oz is a pound man. Oh by the way that is within easily 80 days with one plant thank you very much. Now if you know how to calculate 3 16oz plants you get 3 pounds of cannabis in 80 days in a 6ft tall x 3.5wide x 3.5deep cabinet with a 600watt-1000watt MH/HPS, including CO2, and temperatures around 75-78 degrees F* you will get that yeild easily, by flowering by the 5th or 6th week of vegetative growth, and you will be done with 7-9 weeks flowering with a grand total time period of 10-13 weeks, which is 70 to 91 days TOTAL. > Must I say more... i wont talk anymore, useless to continuosly prove my point.


PS- By having the multiple grow chambers you can harvest three pounds every 30 to 50 days because of the timing of plant growth and the plants growth stage.

I find it very feasable to grow three pounds of bud from three plants every 80 or so days with one cabinet set up. Is is very important to prune and FIMing, super cropping and all of that to create very open and very bushed out plants to create the maximum of 32 colas on one plant, also if you are using the hydroponic set properly and efficiently then you will see even greater results; experiment with these techniques and you will see great yeilds usually all the time.

you get between 12.5oz---17.85oz

Dude which is it?? With a 600W or with a 1KW?? Now you're actually claiming up to 2.5g/Watt in that period?? You sound like you got your grow experience from a seedbank's strain description.. AK47 is great weed, and a relatively good yielder, but the leaf:bud ratio is pretty high..
If you're for real then you need a grow journal outlining this!!! You could teach the scene alot

including CO2, and temperatures around 75-78 degrees F* you will get that yeild easily, by flowering by the 5th or 6th week of vegetative growth, and you will be done with 7-9 weeks flowering with a grand total time period of 10-13 weeks, which is 70 to 91 days TOTAL. > Must I say more... i wont talk anymore, useless to continuosly prove my point.

Yea I'd want to shut up and drift into the woodwork now too..

So now you're getting 32 colas/plant?? Nice..

Like I said if you do everything right in the beginning you can get what ever the plant can possibly give you, If you really want me too show you a grow journal i will have to buy myself all my shit again since i moved into a different house, and then you will have to wait the 10 to 13 weeks for me to show you what is trully feasable. Itll be hard for me cuz I cant afford shit right now and im starting completely from the chalk board and the beggining of germination, but ill fuckin try just for you man. And Ill fuckin prove you wrong in every category explained, then ill show you how you can shorten the time in between harvests with multiple grow chambers.... Until further ado i leave you this thread until then. In the end its all going to benefit me.

I know the tricks of the trade, I know whats possible, and I know the best choices that can be made if you hope to achieve that..
You mentioned 3.5x3.5'.. With 12+sqft lit by a 600W for 50W/sqft,
a very respectable yield, optimized to give the most yield/veg_time (usually a week, but strain dependant) 2lb harvests would be extremely braggable.. That would be more than 75g/sqft, and more than 1.5g/Watt! And to do that, you'd need many smaller plants to keep the bulk of the growth within the lights optimum intensity range.. You can't expect outdoor results on indoor plants.. I wish you could, but you can't..

3 plants with 32 tops... in a 3.5' x 3.5' ????

Won't fit dude... you can barely fit one tree in there.. and you are creating a shade farm...

You can most certainly get that kind of weight... but not with 1 600 watt and most deff. not in a 3.5x3.5 space....

Sorry....

Oh.. and there is nothing that I would love more than for you to prove me wrong and teach me how to triple my yields...

Have you ever seen a big plant?

How can you expect to fit 3 of these in such a small space...???

Won't happen buddy.. unless you squish them in... and then you won't get shit in the shade and mold...

Click on the link above and tell me how you are going to fit them in your cab.... you would be lucky to fit one in there...
