    modular overkill led striplight build

    the square meter tent is doing really well. 200W in total for now, carefully introducing them to some 660nm red. prunned allready a dozen lower shots, but prob. have to cut more. running out of height, hope they stop to stretch soon otherwise they will grow in to the light. overall very...

    A SIP to Mars.

    i have my first soil cooking, which i plan to reuse, so not really much practical clue there. the bat guano i grabbed as it seemed to be good stuff, overall a nice package, many P sources out there. Canada is huge and full of ressources, bet you will find some good shit. i just used a few table...

    A SIP to Mars.

    yes, nothing new to you. had just the same problem in soil and never had it in cocos or any other hydro grow before. prob try to give earlier on bat guano this time, while the soil itself this time is armed with lots of stuff, hmm. tag me if you find something.

    modular overkill led striplight build

    thanks man, absolute, not much space or wattage is needed for personal use. even if youre a heavy user as i am. went really ok for a first try with soil after decades. had the feeling the 200 was allready too much, even 130w is giving good results in this 0.75m2 tent. while i also had the...

    modular overkill led striplight build

    thanks! does it need more space? above is a 86x86cm tent, used max 200W at peak. knowledge isnt really that much needed, but am still experimenting myself, just finshed the above run in soil. some good peat based soil plus a good 10% wormcasting and one should be pretty good.

    weighted the gelato yield from the soil grow in the smaller tent. 340g in total, checked my scale before with a 10g calibration weight. tasting awesome, similar to when i grow her in cocos but way more intense, loving it.

    modular overkill led striplight build

    2 of the do sweet dos no.4 went in to the smaller tent. 2 fabric pots of 5 gallons each, so 10 gallons super soil. good yielding pheno, just a bit lanky, sativaish. as i dont plan for runoff i could get rid of the plant lifter construct and gain some height. hoping it will work out. went in to...

    modular overkill led striplight build

    really like the soil mix. buying worm casting had been a good move it seems as everything is so dam healthy. 7 days on 12/12 now. thats how it should look like. fingers crossed it stays like this for some time. have to say their mother didnt perfromed good production wise, quality was great...

    Worm question

    allow me the joke. All humans are recyclers. All eat organic material and shit EWC for us. Some are better than others.

    the best led lighting to grow

    both terms can be used, np, while SMD is more widely used, basically youre speaking of THD or SMD components, am sure about that ;). for assembly SMT makes a little more sense and its common, but as the componets are more dominant in our thinking, it all becomes SMD. sorry for the nitpicking...

    the best led lighting to grow

    yes, it is what it is. accoridng to bugbee the green light is reflected and bounced and therefore reaching regions red cant. its a factor for "penetration". sure, its not taken the most efficient way and bounced back and forth it wont get more, but its been taken. as far i can see the op is also...

    the best led lighting to grow

    i agree that the plants dont look very healthy and that his light will use still many components made in china with resources from whatever, but well using the term SMD is fine in this regard. "SMD assembly SMD stands for surface-mounted-device. By their connecting surfaces the SMD-components...

    Spinosad..

    i had to think of this when i read the descprition of how nematodes do work. they eat the larvae from the inside and multiply, in contrary to the alien its not only one comming out of the body. BTI is good stuff, i like it cause you can store it. tbh, i have no clue if you have "other" BTI, as...

    Spinosad..

    problem with mosquito bits is that its passive, needs direct contact to the larvae and the attack window is much smaller, it helps for sure, just never eradicated them completly as the nematodes tend to do, they work like Alien.

    Spinosad..

    i second the opinion on nematodes, they always did it for me. when i see one i normally apply first BTI tablets (as i have them stored) next i order a pack of neamtodes. nematodes are quite effective, beeing able to attack the larvae in several stages and actively search for them. your gnat...

    Putting in a second 240w LED

    "The data from Chandra et al. show that cannabis plants are like many other terrestrial plants. In ambient concentrations of carbon dioxide (CO2), cannabis leaves begin to saturate when the photon density is 500 µmol (PPFD). The limiting factor is CO2. This shows up in the data as the...

    Putting in a second 240w LED

    please show and document your side by side, always good to have some to compare to directly. my bet would be the 480W 301H are way too much in the square meter.
