    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.

    yield

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

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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.

    6 week flower

    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.

    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.

    600 is most efficient lumens per dollar wise.

    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

    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
