  1. Your dream controller

    Fan Speed Control As I was looking at the available prototype building blocks I noticed that there doesn't appear to be any microcontroller ready AC motor speed control modules. It is not really surprising since controlling the mains power means getting into meeting standards (UL Listed, CSA Approved, etc.), and that is kinda expensive to do for such a small market (I can't imagine anyone other than prototypers and hobbyists needing such a device). My first instinct was to use a typical TRIAC based phase control circuit (e.g.; Universal motor speed control and light dimmer...), but after a little more digging I came across an AC chopper based alternative I hadn't considered (Single Phase AC Induction Motor Control Reference Design). It is more complicated, but should offer a wider range of control, be quieter (both electrically and acoustically), is very efficient (Power Factor close to 1 = almost 100% of the power being transferred to the motor, IIRC a TRIAC based controller only transfers ~65% of the power), and it will work well with any single phase AC motor (reliable starting at low speeds). There are a few options for hooking the power control to the Dream Controller. A module containing only the AC mains connected components and the optoisolators could be constructed. It would be suitable for very short distances (controlled AC outlet in the same enclosure as the Dream Controller) and manual control would need to be handled by the Dream Controller. The above module could have a tiny microcontroller included, just like in the Single Phase AC design reference linked to above. Toss a slightly more capable microprocessor than what is used in the reference design at it and you can easily include an I2C port (Inter-Integrated Circuit communications, gets you ~2m from the Dream Controller) in addition to a manual control. This would be an upgrade to a basic standalone speed control, with the option of hooking it up to any microcontroller that can handle I2C (probably all but the very tiny ones). Do a sensor/speed control combo unit. Step up to a small microcontroller, hang a temp/humidity sensor off it, do somewhere between a bit and a bunch of programming and it could be a unit that operates as a fancy standalone device or a smart subsystem of the Dream Controller. The sensor units are all I2C devices (hook up two wires then do everything in software), so the main difference between this option and the one above is mostly in the programming. The bits not covered by "mostly" are: indication of temp and humidity; indication of fan speed; input of temp and humidity set points. I'm thinking of using individual RGB LEDs (can be set to any color) for the three indicators and standard rotary potentiometers (or maybe a pot and a button) for the inputs.
  2. Cheese autoflower c/w sap

    It was like honey - sweet and sticky. I let the lowest branch of a Thai Lights flop down into a corner (poor light), after the tent became less crowed and the top of the plant was removed I picked it up and positioned it to get good light. When the plant was drying I noticed that it had also been leaking sap. I'm thinking that the move from poor light to full on CMH is kinds like hooking up a plumbing system designed for a 3/4" supply line to a fire hydrant.

  4. Crowded and too tall

    [where was I before I was distracted by summer, then sucked into watching The Trump Show (may be the best Reality TV series ever)... harvesting the larger Thai Lights because it was mostly ready and really getting fried by the lights.] Not long after that last post I noticed some mould in a bud of the smaller Thai Lights, so I removed it and look off the top of the plant. When the next rainy period came along both of the huge buds on the large African Buzz (the two that had their tips in shadow in later pics) developed mould. In total I lost the five largest buds on the two plants to mould growing along the stem - all of them were so thick and dense that you couldn't see the stem without bending the bud, and a couple couldn't be flexed far enough to see the stem without breaking. I had airflow cranked up to the point where I could keep the night time RH at ambient, but with ambient RH >50%... An active dehumidifier would help, but I'm thinking that the real problem is a lack of air flow through the cola - maybe removing every second budlet/branch in a potentially thick cola is the way to go. Ya, it turn out quite well. The Thai Lights pic-ed above (slim green buds) got me 176g, the shorter one (fat buds c/w purple leaves) came in at 203g, and they have raised the potency bar wrt the LP stuff I've tried more than a little! The smaller, immature, buds on either plant are as good to a bit better than the best from the LP; the mature flowers blow it away. I'm using 1/3 to 1/2 less to get the same effect, at about 1/20th the cost per gram. The phenotype with the slim buds is a bit more potent than the one with fatter buds. The large African Buzz did not turn out very well - lots of small leaves with a very low density of glandular trichomes mixed in among the flowers. A typical dose of either of the Thai Lights is about 1/4 to 1/3 of a regular joint, this African Buzz plant requires 1/2 a fat joint for the same effect. I didn't bother to weigh it out; Ziploc freezer bagged until I get around to doing a solvent extraction on it. The smaller African Buzz is also kinda crappy in the same way, but it's resin content is very high (crumbled bone dry bud moves like brown sugar) so taking tweezers to the buds to pull out the shitty leaves gets me some decent smoke. I'll probably end up dry sifting most of it. I have about 6G of pics to go through, including: mould, fried buds (18" is as close as I want to get to these CMH lamps in the future!), and maybe a few nice buds.

    Thanks, not foil though - textured mylar, part of the tent.
  6. Unknown outdoor strains Alberta

    I've heard that in Alberta your best bet is to start in Feb and put into the ground in April. AFAICT, the theory is that you gain an advantage by having the plant mature (alternate phyllotaxy) before the photoperiod triggers flowering. It seems plausible because I've noticed that I get little to no "stretch" when turning indoor plants to flowering if they are solidly putting out alternate pattern growth, that would get you an additional week or two of flowering. If I was dong it I'd start indoors in Feb., transplant into a raised bed, and be prepared to both manipulate the photoperiod and extend the season with a really big row cover.
  7. Humidifier switch

    I have no clear idea... If the "micro switch" is connected to a microprocessor's input port it may require a pulse to activate instead of a steady state., in which case you will not be able to override it with a simple toggle switch. If it is a maintained contact type of switch (rocker, toggle, alternate-action push button, etc.) then you should be able to (may need to remove the original switch from the circuit board as well). Be aware that lengths of wire are antennas, and connecting them up to microprocessor inputs can result in spurious operation (or worse) in an EMF noisy environment. Keep the wires as short as possible to mitigate. Good Luck!
  8. I think I am ready to Start

    It looks like what I've seen on 4/4 varieties of seeds from one vendor (all three autoflower and the African Buzz), and it also appeared to a small degree on the Thai Lights after they were transplanted into containers previously used for the autoflower plants. I also noticed the symptoms were only appearing on main stem leaves and fan leaves on one or two branches, rather than all over the plant or confined to new growth (the usual patterns of symptoms of deficiency?). I'm thinking my plants have disease, and some bits I've read lead me to believe that infected seed is not uncommon. If it is disease... I don't think there is much to do beyond taking the best care of them you can. With mine the symptoms disappeared from the autoflowers before they were 1/2-done flowering, and only appeared on a couple sets of leaves on the Thai Lights. It appears to be a mostly cosmetic issue (guesstimating an average yield so far of 500g/m2, which is pretty good afaict), but I will be bleaching my containers between use.
  9. Crowded and too tall

    Took down the taller Thai Lights... ...4 bundles of 5 or 6 branches + the top, very leafy, but there are fairly dense and resinous buds buried under all the foliage... ...2.2g of bud from the tip of a thin branch, the tops and larger branches are looking a bit better (another day or two until they dry). The amount out not-quite-fan-nor-sugar leaf kinda sucks, the smoke itself is pretty good though and may have even upped the bar for the LP a bit. This was the first pick when I went looking for seed for the pot I was smoking 30 yrs ago and I'm a bit surprised at how close it is to the memory: a bit more earthy and a little less spicy, with a touch of citrus, but the same basic taste; texture is about right (small leaves and bracts feel thicker, meatier than is typical); and there is a familiar yellow-gold color already showing through the green.
  10. Cheese autoflower c/w sap

    The only 1/2-descent shot I managed to get of the sap which started oozing after the plants moved from T5HO to CMH lighting. The bit of leaf it is leaking from is actually purple, sap coming from green leaf was clear.
  11. I think I am ready to Start

    Maybe all you need to do is mulch with potatoes periodically to keep them under control.
  12. I think I am ready to Start

    ...and fungus gnat larvae! Are they at problem levels? If you have lots they will feed on plant roots, but I betcha they will stick to fungi and dead organic matter if not crowded - a few is probably a sign of a healthy soil. Do they get into the mats in the trays?
  13. Vancouver weed.

    The few tokers I've spoken with who've tried dispensary, online BC based shops, and Licensed Producer weed, all claim that there is nothing "better" about it compared to the black market product. The LP stuff appears to be most disappointing. We are in a city though, things may be different for those in a smaller market.

  15. Lots of room... does it fill up? If I promise to help with the harvest would I be allowed to camp out there?
