Oh, I pop in from time to time. Thanks to joneric1014 for the glowing review. I'll be hanging around for a few days. See: https://www.rollitup.org/hydroponics-aeroponics/399206-its-fuct-world.html

pssst- I'll be here for a few days. See: https://www.rollitup.org/hydroponics-aeroponics/399206-its-fuct-world.html

Thanks. However, I am reliably informed that the frequency is Kenneth. ;) I think there will be a Grantham again. In fact, I'm really quite confident of it.

Getting hit with a several metre tall wall of water without warning would be a LOT worse. Ask the folks in Grantham.

Hay sparky, good to see you too. :) Too right, but only use bleach & urine if also using liquid nitrogen. only for a couple of days, then I'm back to the old grind. Dood, you ARE a w33d b4R0n! The w33di3st! xD cheers! Al.b

HO fluoros are not really necessary for clones. Plain old shoplight fluoros will do fine. As regards the HPS for flowering, just go with a 400 from go to whoa. The 150HPS you already have would make a nice light for mother plants. The plants are not transpiring any water during lights...

Rethink the hempy buckets. The hempy design leaves roots submerged in water- I'm not a fan. Flood tray based systems are not much more complex and don't have this design fault. A good rule of thumb for HPS is 50W/sq ft. You can do up to 4 plants per sq ft IF you diligently prune off...

Seriously, LED evangelists are like PowerBalance band advocates. "WORKS!" they all yell, until put to the test. When proven wrong, the tune doesn't change. Fuck 'em. I really dislike 'Lucas Formula' because it allows (nay, encourages) extreme NPK ratio imbalances. That's part of what's...

How are the LED evangelists doing? :D 35% will do fine. Low strength H2O2 has a stabiliser added (normally sodium silicate) which is not plant friendly. AFAIK, 35% doesn't require stabilliser, but much lower than that does or the shelf life is rather short (about a year). I know, it's hard to...

I would recommend Canna, strangely enough. ;) No, they're not paying me to say that.. but hey, Canna... if you're listening... there's enough room in my garden shed for a few pallets of gold bars. :D There's several high quality inorganic nutrient mfrs, though. Someone will chime in and...

It ain't so. Happy? :D Really no good. I'd like to fly to the moon with a propeller beanie. Any slimy feeling on the bottom of the nute tanks? Applying regularly every 3-4 days? Any chance the roots could have been dried out or drowned? I had a timer fail not long back- it was...

If you can control the scent of your plants, you'll be able to control the scent of the sulfur, which goes away very quickly once the sulfur in the evaporator re-solidifies. The sulfur vapour will also leave an invisible residue on ALL grow room surfaces, which will kill mould spores...

The high ppm is being caused by Mg & Ca, both of which are essential nutes and will not contribute to nute burn, which is caused by excessive nitrogen. Subtract the tapwater TDS figure from the TDS you mix to, i.e. if you want 1000ppm and tapwater is 520, mix for 1520ppm. H2O2 is not terribly...

You're not hijacking at all. I'm here for a few days specifically to answer queries like this, but thanks for your politeness. :) It's really hard to overuse H2O2. It's so hard to overuse it that I can't really tell you what the symptoms would be. I've never deiberately exposed a plant to...

On flushing: The only thing you really need to flush is your toilet. There's no particular need to flush or leach cannabis plants before harvesting, but you can do it if you want. The plants store about 2 weeks worth of nutes, so you can safely give plants plain water, no pH correction needed...

flamdrags, good to hear that everything's working for you. I'll be haunting RIU for a few days on this thread.

One more comment on using bore/well water; it's pretty unlikely that you'll have a chlorination system, meaning there's no pathogen inhibitor in your water. Chlorination in muni water will prevent most pathogen growth until the chlorine evaporates, which takes about 1-2 days in an open rez tank...

While I'm here, I've got to comment on 'magic sauces.' I was in my local hydro shop the other day and noticed they've expanded the range of magical rubbish by a factor of 2, at least. If you're using a good quality inorganic nutrient (I use Canna nutes), you simply will have no need for anything...

Well/bore water can cause problems, particularly if the salinity is high. Get your water tested. You may find some state/county extension resources for free or very cheap water quality testing. Failing that, check with a local university. Gotta know what you're starting with. Brita filters...
