    SM-90 vs Dutch Master Zone?

    These products seem to fulfill roughly the same purpose, so which do you think is better?

    Running a sterile reservoir? (hydroponics)

    Is there a good resource on running a "dead res" anywhere? Initially I neglected any biological or sterilizing agents, ran into some problems, tried H2O2 and got poor results, switched to bio-control, then over the course of a few grows went so far as building a vortex brewer; I've tried a...

    What is YOUR preferred method of trimming, and why?

    Personally, I like to take it in planes from the top down, so first all the colas, then the tops of side branches, etc. so that the lower buds get more light as I'm trimming the tops, then I'll trim and manicure everything wet by hand, and dry the individual buds on a rack. Going by hand while...

    Trichomes on leaves vs buds?

    I've gone through a numbe of cycles, but after my first I gave up with the trichomes as harvest indicators because I felt things were fairly obvious from a whole plant view of "ripeness"; that said, I've always wondered, does one look at the trichomes on the buds, or on the leaves? The leaves...

    Severe wind burn, any advice?

    So, I was unable to check the garden for a few days, the lights came on about half an hour ago, and I discovered that my oscillating fan decided it was going to break; the fan itself kept running, but without oscillating, meaning that it was pointed directly into the top of a plant... probably...

    Back to the Future!

    It's been a long time, and I feel like another grow journal! Backstory: I used DWC a while back, but quickly moved into aeroponics because, quite frankly, I still haven't figured out an easy way to change 5gal bucket reservoirs; plus, aero offers other advantages, and made more sense for a...

    Extreme dehydration?

    A few days ago I discovered my AC had gone out during my evening check, and temps had hit 100F; so, I installed a window fan, and a couple pedestal between the AC in another room and this one, which brought temps down to acceptable levels... however, I forgot to account for the heat of the day...

    Leaf tips curling up, hard!

    I had what appeared to be a magnesium deficiency a few days ago, using Dyna-Gro nutrients, and after having trouble with pH, I decided to switch back to General Hydroponics; this looked much better, but then today I noticed some serious leaf curl on a few. The first two are the two with curling...

    Root rot in aeroponics; do solutions even exist?

    Alright, so what do you do about root rot in aeroponics? I have two aquamist systems (2'x4', 32 plants suspended above the reservoir) which I fill with about ten gallons, each has it's own 20lpm air pump. I've done a lot of research on this, and it appears that while there are lots of...

    Why is this plant wilting? Aeroponics

    Tent was recently sealed for three days (R/O only in res), humidity was quite high, clones transplanted two days prior; looks like over/under watering, but it's got a good set of roots, and I'm as a loss. During this time a bit of cobweb mold showed up, but it's died off a good amount in the...

    Wilt (just one) and cobweb mold (minor?), pictures etc included.

    Alrighty, so a few days ago I noticed some mites, five of them, and went at them with shock and awe; each plant was sprayed down with neem, apparently enough to run down and kill the beneficials in my reservoirs; I then decided to change the reservoirs, and discovered my pH electrode was faulty...

    Fuzzy/cottony growth at base of plants

    I saw the first sign of mites a few days ago, so I hit everything with neem, sealed up the tent, hung a No Pest Strip, and they saw ruination; upon opening it all the mites were dead/gone, however the humidity had spiked, and I noticed this fluff around the base of a couple plants. Other than...

    Pro-TeKt pH problems

    So, I use to use MaxiBloom as a base nutrient, but then I switched to FloraMicro + FloraBloom; Pro-TeKt was great for balancing my pH before, but now I just want to kill babies. No matter the order I add things in, pHing the Pro-TeKt alone, whatever, I hit a wall at ~6.0; however 12 hours later...

    Lack of light? (pics)

    I'm assuming this is due to lack of light, that B1 keeping internodes tight as fuck (sativas staying shorter than indices, with more side branching) and causing a VERY dense canopy. Lowest leaves/side branches are dying off, but drying out immediately so I know it's not mould. I figured it was...

    Something on roots?

    Doing my daily checks, and noticed a couple plants with stuff on their roots/not white roots. pH: 5.8 PPM: 1000 R/O Cal/Mag Pro-TeKt Maxibloom Compost Tea (5ml/Gal MycoGrow, Soluble (added after brewing); 6ml/Gal Organicare, Seaplex; 38g/Gal Progress Earth Organics, Earth Compound; 4ml/Gal...

    Electricity rates and usage

    For my current cycle, I decided to run things at night, however that time period has not been working out great for me, and I would like to run things during the day. After calling my power company, I've found that my area does not have on/off peek power rates, it's just the same rate all the...

    Tip on Foliage

    I can't tell you how many grow videos I've seen where someone speaks as though they are an expert, and might in fact be one, yet they cannot pronounce foliage. Look at the word, it's not spelled foilage, and as such, is not pronounced that way. I'm sorry, but this is a pet peeve of mine, how...

    Compost Teas?

    So, I've read about these teas, and after running into some root problems on my current grow, decided I should get on that, at least as a preventative, as I saw way more root development after adding the tea than I did when I used h2o2 - also, h2o2 never fixed any problems. I have the fungal...

    Bleaching?

    Alright, well, I've read through all the stickies, as well as a few other pages, and I'm not quite sure what the problem is here - it's probably calcium/iron/magnesium/zinc, but I'm not sure, and I don't want to start acting on a guess. Recently I noticed root issues, and a couple plants wilting...

    Total wilt over night.

    Alright, so I went in today to find a plant had totally wilted, all others in the same system are doing fine... I'm kind of... at a loss. I'm going to go back in and check levels and everything, but wanted to throw up a post first. I typically start with R/O water, Cal/Mag to 150PPM, then...
