heat typically denatures enzymes rendering their active sites useless.

i think we're talking about two different kinds of roasted barley. the kind i use isn't used for brewing. it's made into a very light tea (for humans). tastes like popcorn, not bitter or chocolately. regarding plants not being able to use hormones or vitamins, perhaps folks aren't familiar with...

have you ever looked at an A/C coil? i've never looked inside a portable unit, but i have seen the inside of a central A/C and that shit can get moldy/mildewy in a hurry. there's no way i'd ever use it unless i was in BFE and had no other water. that said, when my condensation drain backed up a...

i use real kelp (from asian grocery store) and powdered spirulina. the kelp, i soak overnight to get some of the salt out of it. then i grind it up with roasted barley (also packed with vitamins, hormones, carbs) in a blender, add it to a 5gal bucket of water, and bubble it up with great white...

i've been running aquaponics in my grow room for cloning and veg, even adding nutes. currently running at 1200-1400ppm. about 500-700ppm is from the fish (when heavily fed). mostly feeder minnows (which are indestructible), a few feeder goldfish (most died), and an algae eater. to me, your...

me personally, i'd go with 8 plants vegged to about a 12-18", topped twice, that are nice and bushy. i also like to prop the outer plants with small crates, buckets, whatever to achieve a stadium effect. new plants go in on the outside, peaking plants in the center, then back to the outside for...

there may or may not be benefits to UVB. i'm sure there are, as natural sunlight contains UVB. however, bud mold needs UVB to complete it's life cycle. when i tried adding UVB, i got bud mold on the next harvest despite r/h well below 50%. haven't used it since. realize that sunlight also...

10% loss but 2wks faster seems like a fair tradeoff. i don't think you can necessarily attribute the loss in yield to light hours, though. you probably would've gotten that additional 10% if you flowered for another 2wks. so, yes, reduced light hours are responsible for a smaller yield but only...

schweet! looks like you're getting much better light utilization. check out this dude's "figure 8." i like to pack 'em in close together like this too in circular fashion. basically if you look at it from the sides and you don't directly see a lot of light peeking through, then your plants are...

well, not to beleaguer the point, but again, i don't think florigen is destroyed. it's just the final, bioactive forms of it never form. the precursors still are formed, which alone, don't cause flowering as they aren't bioactive (there are no receptors for them). same result: prevention of...

i'll try to respond to various posts, but my point isn't to win an argument or convert anyone over to the dark side. just want to make sure we're all talking about the same thing. sounds like there was some misreading of my last post. clarification is for the sake of others who may read and...

if 12-1 was causing flowering, wouldn't all my plants in veg, especially the ones that are same strain, roughly the same maturity be flowering any day now too? they're not. my guess is that 12-1 acts as a sort of hormonal primer. hormones just don't appear out of thin air once you've made the...

the biggest difference i've seen in stretch in the strains i've grown are between papaya (close to full indica, i think, really shrubby, almost mini), with almost no stretch, and maui wowie (full sativa, i think), which went from about 6" tall when i put it into flowering to 4ft in about three...

i don't know if it's from vegging in 12-1 for a week or two or from also switching to an 11/13 in flowering, but the plants i put into flower 5 days ago are flowering like crazy. normally, it would take the same strain, same size about 4 weeks to pop like this. also changed feeding schedule...

i'm telling you guys, my shit is drawing way more power than 23 watts! finally compared it with 100watt incandescent to prove to myself that i'm not crazy. sure enough, the load tester is accurate. appliance load tester with nothing plugged in = 4watts 100watt incandescent (+load tester) =...

seems like a lot of the light is going to be blocked by the bulb itself, as with all CFLs... please update pics of your 2000w CFL grow! curious to see how things work out.

it's not crack: it's ready rock. pretty sure it's showing constant, as the number fluctuates a bit. going to check wattage of 100watt incandescent to make sure the load tester is calibrated properly. try it yourself! got a load tester from HD/lowes and plug that shit in!

and to keep the shape somewhat cylindrical, i bend the top of the cage over. that gives the thing some rigidity so you don't get an oblong or flattened cage shape.

you've got 1000w HPSs going in there? maybe start with a 12" radius between bulb and cage to start with. if you don't see heat stress or burned leaves (looks kinda nute burn), then you can cinch it up tighter? i overlap the chicken wire then cinch it together with zip ties. be sure to use...
