Lazy Man's Way to Cleaner Hydroponic Cannabis

[Douglas.Curtis]

ahhh okay i get what youre saying now makes sense but its funny you say that, in the winter when my res temps were like 60-65 it took like a month and a half for my plant to reach a foot but i also hear the higher temp can result in low dissolved oxygen and obviously pythium but right now my temps are like 74-80 (depending on temps outside) and theyre growing more than ever

That swamp cooler, evaporation going on is great

you both seem knowledgeable so this question is for both of you...I have what im 99% sure is cyanobacteria that comes back after a week or 2 of res/tray cleaning/sterilizing... no matter what temp or how perfect everthing else is, it always comes back... i was using 29% h2o2 @5ml/gal every 3 days but even then itd still be back after 2 weeks. right now i been trying pondzyme with hydroguard for a week and im starting to see a thin film of it.. my question is do you guys reccomend anything for this? have either have you had this problem? its a clearish snotty/gelatin like substance that floats around or sticks to the walls. ive looked into the heisenberg tea and i might order the materials tonight but is there anything else you guys would reccomend? i have a 2x4 flood tray with a 23 gal res, plants in hydroton

Dealt with this and it's disgustingly nasty.
The tap water at one location was an infected well. Simply rinsing something in the local water and using it in the res would produce snot in 3 days.

R/O machine, all the way. Whatever methods you use to get rid of it, use r/o water for it or boiled tap water. Easiest way is to start with all new equipment. Cheapest way is to use biologics or antibiotics to get rid of it on EVERY surface in the garden which will touch nutrient solution.

Clean bottles, buckets, hoses, pumps, airlines, stones, the more difficult to clean, the more closely you should look at simply replacing it. It took me a while to understand what was going on and even longer to fix it and learn to work around it. I don't envy your position.

chlorine AKA HTH pool shock or dutchmaster Zone. sterile res all the way

When you follow my recommendations, this is not necessary. I firmly believe in adding only what cannabis requires for growth in the res, chlorine is not required for growth.

rootzone temp and root temp are 2 different thing. for your issue ,if it keep coming back it mean u have something wrong like light leaks,high temp, stagnant water,organic additive.

hydroguard should fix your issue, drop the pondzyme until you have white fuzzy roots then you can start adding some to your rez, if it come back again, stop using pondzyme.

should check your sources: chlorine is a tertiary nutrient of cannabis and IS used by the plant.

look at the ingredient list for dynagro bloom: it's in there.

yeah i was thinking about replacing all hoses, airlines and stones are each harvest anyway but even with r.o it would come back (probably because the bacteria was still there from using tap water before) i only have 1 tray right now but want to get rid of it before i get any more so maybe i should try a antibiotic treatment on this tray and stick to r.o only moving forward im just scared to use the antibiotic and it not work properly and i get a bunch of immune super bacteria floating in my res

changing rez every 2month definetely not result in a ''cleaner'' product. element are uptake at differente rate, micro nutrients ALWAYS accumulate , if you top your rez with nutrient, ur always adding more micro resulting in increased build up. theres like 0 reason to not dump every 2 week at leastt

what nute line do you use, dynagro? i heard its ph is a lot more unstable than the maxi series... do you use the pool shock or the zone? that stuff protects you from cyanobacteria? h2o2 couldnt keep cyano away so i need another weapon

i was thinking that... my tray isnt on an angle, it stays flat...and theres some water that stays stagnant in the drain hose between floods, maybe this is the cause of my problems.... you think the hydroguard should work to get rid of the cyano?

Not in the levels needed for sterilization. At those levels it is excess and a contaminant or worse.

chloride and chlorine arent the same thing.

yep puddle of water is common issue in flood table but since you are probly flooding 4-5 time+ by days i dont think its your issue.

hydroguard should control the disease but it wont cure. its used as a preventive. theres no cure for slime because its not really a disease but the result of a poor environment.

ro dont sterilize water... only way to sterilize tap is chlorine or UV

I'll pit my 3 month flower against your 2 week changout, any day. I live in Fairplay and my next harvest will be in about 3 months. What's more, in time, I'll be able to pay for lab tests as well.

I have zero hesitation in stating my cannabis will come out cleaner than anything the methods you're advocating will produce. Zero.

 

[Douglas.Curtis]

r/o removes the cyano, which is much larger than the particle size the r/o filter allows through. It's fine.

wtv im not trying to change your methods, i just tell you the fact.

if ro would be a safe method to sterilize ,cities would save a lot on chemical........ only way with ro is uv or chlorine as I stated

dg foliage pro for seedlings, then flora duo for rest of veg and all bloom

i've used both zone and pool shock. zone was a bit easier to use/measure but will break down over time.

right now, i use 0.30 grams of shock per 10 gallons RO. just need an accurate scale to measure which are fairly cheap anyway. so a 1 pound bag will last 5 years maybe?? lol.

 

[rkymtnman]

care to quote a source? how do you even know what levels i'm running?

since you don't, i run 4ppm which is within the safe levels for cannabis. and it's a sterile environment too.

most muni water uses chloramine instead of chlorine but you are correct. and to replace RO membranes on a huge plant would be ungodly expensive to boot.

well i flood 4 times a day but the stagnant water becomes really warm just sitting there but i just but the tray on a tilt... so maybe i should just run a full antibiotic cycle (or use heisenberg tee for like 2 weeks) then get back to using hydroguard plus a res change every week for flower and every 2 weeks in veg... i hope that will fix it

yeah i already have one that can weigh that and i actually already have pool shock and r.o filter at my house... so you only add more shock on res changes? the only thing that sucks is i cant use hydroguard with it, i wonder if there are any benefits with pool shock besides just pure sterilization

 

[Budley Doright]

I have a great respect for hydro guard after it saved my grow last season, nothing stopped the rot, and cured it, except hydroguard, bleach, shock and H2O2 never touched it. Also
