  1. Could I get good enough temps in a grow tent that's 32x18x36 inches? I have a 240 cfm fan that I have connected to my ducting I have set up with my tent. My fan pulls hot air from the tent.

  8. Ok your not going to get 7 ounces off one plant. Veg time plays a giant role in how much you will get on average. Each strain yields different amounts too. So I know your looking for a magical answer but there isn't one. Technique and conditions affect so much that you can't base your grow off others. You can get a rough idea but by all means it's a rough idea. With that said my 400 gives me on average about 2 ounces per plant. However that's "on average" some strains give me an ounce or less each time. Some strains give me almost 3 ounces each time. But on average I yield about 2 ounces per plant with a month veg time.
    Fox farm nutes. But I'm too lazy to go back and look at everything you wanted to know. I just waked and baked and I feel like that would ruin my high to scroll back and forth between your demands and my lack of motivation at the moment. That's all ya got Fred.

  9. I got 12 ounces off a scrog with T5s so don't tell everyone you got 7 ounces with a 400w high pressure @ManNamedJed
    Some people might laugh at you.

    2 400w mh for veg
    1 400w hps for flower
    Organic Compost with half perlite
    3 mo Veg
    Flora Nova nutes
    Molasses
    Epson Salt
    Oyster Sell Calcium pills
    6.8 ph
    Water twice a week
    Nutes every 3rd watering veg and every other for flowering
    Little over 2mo flowering. Cut at 20% amber tricoms.
    Dry 5 days then cure 30 days in jars
    I'm sure I forgot something. Adding another 400w hps next round for flowering cause off 4 plants the yeild was only 6oz. This is only 2nd grow and always need pointers.[​IMG] half strength on nutes.

  13. My first grow 2x4x6 closet. veg with 400mh flowering with 400hps. 5 transplants in 2 months final pot is 13.5 gal. Foxfarm nutes. 6 more weeks of flower. Bushy one is cheese/ghost train haze other is mexican bag seed and she stinks. Hopefully I end up with big sticky buds and a nice yeild. 20170612_110252.jpg 20170612_110252.jpg 20170612_110518.jpg 20170612_110518.jpg

  14. Dwc 12gal tote
    Chiller at 10°c, ambient temps keep the res at about 15°c
    137gph air pump w/2 stones
    400w MH... Hps is waiting for it's moment
    Two weeks from seed are the dwc
    The orange (3gal) and black (1gal) pots are 60% ffof 40% perlite one week from seed.
    And the two in the starter pots are 50/50 Coco and perlite and they just sprouted a day or two ago.

    No yield yet but I figure why not show the differences in mediums vs wattage? I have two LED panels at 140w a piece but idk... I think the medium is most important. Learning curve number 1. Next would be light intensity. My LEDs, side by side, couldn't cover half of my 2'*4'*5' tent as EFFICIENTLY as the 400w. They have no problem lighting it up but I ran two grows under them, the first was a dwc 5gal bb that yielded me a lil over a qp, and the second in ffof 7gal fabric pot only got me about 1.5 zips. Same light same tent same ambient conditions different mediums. So I went back to dwc, this time I grabbed a chiller and a 400w cool tube with carbon filter fans and ducting taking the old/hot air directly outside. My outlook feels much better this time.

    The explosive growth under the 400w metal halide is incomparable with that of 280w of LEDs (mine at least).

    I've been following this thread for a while now, I just wanted to give my $00.02.

    And I will update once 12/12 has been established, as well as the harvest following.

    GLG!

  15. This is my first grow and I have three plants. since these are miscellaneous strains and were meant for me to "practice", I have topped two of them, lollipopped all three and super cropped all three. These are pics from last night. (Week 4) of flower. Let me know what you think. Like I said, its practice before I start my strain of White Widow. Happy growing and remember, Grow Your Own!! 20170927_170143.jpg 20170927_170253.jpg 20170927_173451.jpg wn!!
