  1. ledfoot


    Boudica is my favorite strain that I've grown in modern times (since the early '80s). I've done maybe ten plants of it. I'm on an extended break now but I smoke (bong) all day, every day. Grew four plants of Aztec Rain last time and I'd have to say I was disappointed. Real sativa in this sense: after the first hit, saying "That was pretty good; I think I'll do another" BUT then later on, feels almost like couchlock. I did a lousy job growing the AR but I think the effect was accurate (for me).

    What do you listen in this moment ?

    I do indeed despise pop country. Back on topic: http://sundaybaroque.org/listen/

    Need help with ducting...

    Homedepot: 10 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket I used this in my attic, connecting a 8" mix-flow S&P inline fan with a 12" hood at the peak of my roof. I mainly wanted the insulation to prevent condensation during the winter. Very quiet. I bought strips of black neoprene rubber from zoro.com to suspend my fan. Works great. Edit: but not absolutely quiet. If you are moving air, there is going to be some noise.
  4. I got bitched out in the past for asking what market a person lives in, so I have nothing to offer here.
  5. In case anyone is wondering why I'm posting this here, it is because the president of the High Volume Oxygen company has threatened to sue people (including serving papers, I guess). The (BS) HVO patents are here: https://www.highvolumeoxygen.com/patents/ Background: http://www.talkglass.com/forum/showthread.php?64885-oxygen-frog-verses-high-volume-oxygen-pro-and-con-im-leaning-toward-frog-thanks-craig I've made two changes to my design after watching the Torch Talk videos. I was planning to let the concentrators run continuously. This would be wasteful but manageable, the wall exhaust fan would prevent excess pooling of oxygen in the work area, I think. The solenoid bleed valve on a timer is a more elegant solution. (What is needed is for the sieves to purge for a minute or two before the oxygen reserve tank is filled.) I was planning to purge the holding tanks at the start of each shift but would need a flow restrictor for the initial part of the fill. My new plan will slow the compressor down until the pressure is about 45 PSI. The speed control will be accomplished with an autotransformer from Parts Express (with a fuse added to the secondary). A PWM fan control would likely work but the transformer should be smoother. I would guess Oxygen Frog uses variable PWM. My design is a two-speed arrangement after the initial adjustment. Edit: I love zoro.com (a division of Grainger). They run this discount several times a year (good through the 24th): I've seen this compressor used most often by DIY people: https://www.zoro.com/gast-piston-air-compressor-16hp-115v-1ph-1hab-44-m100x/i/G1222715/ You will find the flow/pressure curve at gast.com. Edit2: A good explanation of autotransformer motor starting: Theory Of Operation - Autotransformer Starter.pdf (but not really the same thing as the use in my design.) I'm quite sure the Gast 86R uses a PSC (permanent split capacitor) type motor. And I can de-rate the primary fuse in the Parts Express variac to protect the secondary circuit. Edit3: The timer contacts need to be rated to handle the inductive load of the solenoid. If not, the timer should operate a power relay coil instead.
  6. I've decided to move to another location before I build a glass studio. This is a commercially available HVLP system: If you want to know more about the concentrators:

    My New Mission Quest and an S.O.S

    Hi Mike, I haven't seen any posts on other forums that would recommend an especially good trimmer for your operations. I wasn't sure why a Canadian would care much about Jeff Sessions but I guess execution is an attention-getter: https://www.thecannabist.co/2018/03/22/jeff-sessions-marijuana-death-penalty/102131/ Update from last month: http://www.sandiegouniontribune.com/opinion/editorials/sd-trump-sessions-marijuana-20180416-story.html
  8. May Day celebrations in England came under fire by the Puritans in the 17th century. They claimed the holiday was a time of reckless sexual conduct, "a hundred youths go into the woods over night...scarcely a third of them returned home undefiled."

    Aztec Rain advice

    My last grow was five Aztec Rain plants. I got discouraged by leaf miners and reservoir mold early on. So I pretty much butchered the plants and buds with too much LED light. Anyway, I didn't get much odor from mine. The buds have been jarred for a month and I just smell a generic hybrid sourness. These pics are five days from harvest, a total of 61 days 12/12hr.

    Hamme Hydro's Phototopic

    Excuse me for drooling at the wad; thanks for sharing, Hamme! I just got a text from my local rec store offering 20% everything (so people can stock up for 4-20) but the jerks no longer carry any hash. Oh well, you are giving me incentive to restart my grow.

    Can anyone explain some LED science?

    I've never seen a high PAR luminaire that wasn't visibly bright to the eyes.
