yeild with a 400 watt hps?

[dopet4h2c0]

i was wondering some of the yeilds you guys have pulled with a 400watt hps and what is average,low and high end thanks

[WashougalWonder]

You could get anything from 0.5 to pounds depending on all the variables

Hey dope. I just did a 400w MH/HPS grow with my Hashberry. My over all yield was just shy of 6 1/2 oz's with 5 plants. That's not neccesarily alot but you factor in how many watts/plant and what you're feeding them and any bloom enhancers as well, my grow was very low key and low maintinence. Mandala is good for someone who doesnt have alot of time, they draw most of the nutrients they need through the soil, but bloom enhancers work much better.

[drgreenleaves]

guess to about a quarter gram to three quarter gram per watt of light. the variables of course are growing style and plant strain.

[dopet4h2c0]

kool thanks alot for the info i think if i got 5 or 6 ozs i would be very happy thanks again everyone

[krisk1227]

10 autoflowers 11 ounces, depends on strain and such. 600 watts 14 auto flowers almost a pound, With the right autoflower. lots wont produce this much.

[RoundEye]

In my flower room I have three, 400watt hps lamps. If I am flowering with 3 plants per light I'll get 2.5ounces per plant, dry. When I cut back to only having 2 plants per light, I get a bit over 3 ounces per plant dry. I usually veg for 5 weeks and flower for 6.
It's actually better to have fewer plants and get the small increase in per plant weight than to try and cram 3 under each lamp.

[dopet4h2c0]

thats kool i was thinkin maby goin 4 plants in 5 gallon pots think that would do ok? and in a 5 gallon pot i hope ill be able to pull at lest 1 oz per plant if i get everything right like fertz,ph,ventalltion,heat control....iv been reading like a mad man here you guys are have good info so ill just keep readed and learning before i do anything thanks for all the posts everyone

[RoundEye]

You will get a lot more than 1oz per plant in that setup, even a poorly producing plant will give you more than an oz.
3 plants under the light, make sure you top them and lollipop them. You'll easily get 2oz per plant. Veg for 4-5 weeks and flower for 5-6 weeks.

[dopet4h2c0]

kool but flower for 5-6 weeks? the plant i had in mind needs 8-9weeks to flower i never heard of a plant only needing 5-6 weeks witch one is that and is it any good?

[RoundEye]

I've never flowered more than 6 weeks. I don't go with what claims are for how long something should flower. I just watch the plant and use all the normal tell-tale signs that they are reaching their end.

[dopet4h2c0]

oh ok kool thanks for the info you got any pics or your grow? with the 400s

I'm not going to argue your method, but I will argue that you are telling someone else not to flower for more than 6 weeks. If you have never flowered past 6 weeks yourself, you don't know what you are missing. I would also advise that you not suggest it to someone who is just starting. You may not care about the quality of your meds, but some out here depend on quality for ease of life. Do you have any evidence that your buds are better at 6 weeks than 8 or 9?

Stick with your original plan of 8 weeks plus (indoor generally takes a week or so longer than breeders claim). Don't cut yourself short on time, or you will lose flavor,smell, yield, and THC most importantly. Invest in a magnifier so you can look at trichromes and determine ripeness for yourself. Plenty of "when to harvest" info on the site.

I run 2 400s right now, but I have been using them for the past 3 years. Feel free to check out the log in my signature or any of my others if you want to see a grow from start to finish using 400s. I have also been using BioBizz for the last couple years, and love it:thumbsup:

Regardless of the number of root systems, ( I have grown 5 up to 15 under a single 400) every grow in a 4'x4' tent with a 400hps has given me between 6 and 8 ounces. Hope this helps some, and best of luck on your grow.

Here's a smattering of pix

Was merely giving my method, not instructions. I've always sort of figured that every post in the forum has an unspoken disclaimer of "strain dependent". My grows work just fine at 6 weeks flower.

[irydyum]

Veg for 4-5 weeks and flower for 5-6 weeks.

My bad, those read a whole lot like instructions to me. Have you ever let anything go longer than 6 weeks? What strain are you growing that finishes in 42 days? What do you use for indicators that it's finished? I have had a few samples in my day of 45 day weed, and while a few have had good flavor, none had the level of potency that an 8 or 9 week plant had.

[dopet4h2c0]

thank you all for the posts you guys have been very helpful and like i said in my other posts i will keep reading and learning here untill i am ready to give it a run oh and do you think 5 gallon pots are good or should i go smaller? i see alot of people saying 3 gallon pots is all you need but then others say bigger roots mean bigger buds so whats your thoughts? thanks again everyone

thats not a good idea. you are missing out.
i have strains that take 11 weeks.
I use 30x scope and harvest when trichomes are cloudy turning amber. sometimes only cloudy.
personally I have never flowered under 6 weeks.
what strains do you grow that takes less than 6 weeks?

and i grow with a 400 watt in a 2x2 tent. 100 watts per square foot. i love light. yield really depends on the strain I grow. Flowering time depends on the strain I grow.

[Shovelhandle]

12-16 oz

[drgreenleaves]

i would love to get my hands on a strain that finishes completely in 6 weeks. do you know of any? the fastest i've dealt with is what i'm running now, grandaddy purps. it is an 8 weeker. reading certvantes book, marijuana horticulture, in the chapter case study where they give you a garden calender, it calls for 6 weeks of flowering and i was totally thrown by it. i would love some enlightenment.

[RoundEye]

I know nothing of the strain, other than to say it looks like a heavy indica. The buz is such that it couch locks me big time. Going longer in flower would only increase that.
It was a test I was doing for a friend with some bag seed. I initially thought it was some form of auto flower based on how fast the buds began to form. By the second crop, I wanted to save this for the future so I took one of the males and a female and sat them in a room by themselves to pollinate.
As is always the case, 6 weeks is my max for these girls. If I went 8 weeks or more, I'd end up with buds crumbling on the stem or be too stoned to get off the couch.

[dopet4h2c0]

thanks agian everyone for the posts and is a 400 watt to much to run electricity wise? or and i get away with a 600? and a 250 watt MH for veg?

[drgreenleaves]

600 is most efficient lumens per dollar wise.

[dopet4h2c0]

but do you think a 600hps and a 250mh and a 125watt fan are to much electricity to run in a 3 bedroom house with all the other things a normal house runs? thank you

[jtsik330]

No thats just about 1Killowat of electricity and your not going to have all that on 24 hours a day so it should raise any alarms. Call the electric company and get a quote for a fishtank that runs 1.2 killowatt an hour so they put it in your account info:thumbsup:

[dopet4h2c0]

kool thanks alot i wanted to go with the 600hps but if i got to call the electric companay i dont know ill prbly just go with the 400hps lol i dont want to raise supision and 400hps and 250 or 175mh and a 125 fan should be ok i would think right? thanks again

[lampost]

kool thanks alot i wanted to go with the 600hps but if i got to call the electric companay i dont know ill prbly just go with the 400hps lol i dont want to raise supision and 400hps and 250 or 175mh and a 125 fan should be ok i would think right? thanks again

A 600W will not raise any suspicion!

[jtsik330]

Honeslty just spend the extra 20 or so dollars and get the 600 watt. The problem is you need good ventilation to keep the temps managable if it is in an enclosed space. If not in an enclosed space then you are good to go with the 600 watt. I bought 2 400's cuz I thought the more spread light will be better. NOw kickin myself in the ass cuz I would've loooooved the results with the 600watters.

[dopet4h2c0]

gotcha yea i will be buying a air cooled hood with 6" air openings on both ends so i will hook my 125watt fan with 440cfm righton one of the opeingings that should get rid of most of the heat i think cause thats alot of air being put though right? and ill buy a hydro hut so i will need the ventilation so the 600hps with 250 or 175mh is what i will with i think lol...and ill do 4 or 6 plants soundin good? thanks again all

[demoreal]

600 watt is like a new plasma tv with suround sound super tecknar 3d effects blaa bla bla.

600 watts nowadays is nothing.
in Georges grow bible his rule of thumb was 1000 watts per bedroom.
3 bedroom house
3 1000 watt bulbs

[dopet4h2c0]

really thats kool so i should be ok then with the 600hps that makes me feel a lil safer but i will still be runing a house full of appliances so my bill in the winter mite be like a $100 and in summer probly like $150 its a lil high but lie you said 1000 per bedroom and im not comin close to that thanks very much anyone here been runnin a 1000 watt for awhile with no problems? if so tell me about it or if you can show your grow that would be helpful to me and put my mind at ease... and im not talkin about any legal medical states casue my state is not one of them sadly well thank you all again you guys/girls are very helpful

[RoundEye]

If I were building my flower room again, I'd go with a 600 watt lamps for sure.
The cost difference would more than be made up by the gains in yield.
600 watt lamps, and plant in 5 gallon pots. Matter of fact, maybe I'll upgrade this
weekend. I know I could hit 4oz per plant with 600's. I can give a real-world
cost analysis and comparison if I go for it. Could yield some wonderful data.

[dopet4h2c0]

now thats what im talkin about round eye go for it and please post it up here...u really think you can get 4oz per plant? and how many plants would you go with? i was thinking 4-6 in 5gal pots but you tell me
