Haifa is excellent quality. Professional greenhouses use 2-1-2 for general leaf crops. Like Haifa suggests, use a 2-1-3 or 2-1-4 throughout flowering. i.e. Polyfeed GG 16-8-32. Fatman admitted to personally using 2-1-4. They don't mention Calcium or Magnesium ... I hope they're in the...

I have to correct myself again. per his site, the latest PLC6 is ~10% more efficient than Gavitas 600 (i.e. 1100 umol/s with 50W less). You'd need TWO plc6 to equal one Gavita 1000DE at 2100 umol. That's 1182W of COB LED to equal 1064W of HPS (consumed). The hypothetical 662W light above...

The photo red is actually much more efficient than whites for ppf (more but lower energy photons). This is their easy cheat to bump ppf/w but not ideal for plants. 10x 4000K + 2x 635nm per pcb give a ~1.0% peak at 635nm; right in the meat of the mccree's action spectrum. About 11% more ppf/w...

I'm not on here anymore. just happened to find a thread related to something I'm researching and saw an alert. read my post again. follow it. do it many times. try out different things. maybe you're asking hydrobuddy something invalid? what ppm are you targeting, and what is the result...

I was doing some estimating just this morning. Many parts are super expensive to build a single 520W light. You have to get into the hundreds before it comes down on par with commercial units (and that's if you diy). fwiw, a single 4 foot length of heatsink is cheaper than four 12" lengths, or...

fwiw jack's already has plenty of magnesium. drop the epsom! i.e. 3g jack's, 2g calcinit per USgal. just maintain your EC. Everything is already there in adequate amounts (perhaps a couple ppm iron will help). if you're getting more leaf than bud, learn to manage EC and water better. KISS

Those are the things we're talking about - climate, EC/pH, CO2. It's usually the grower's fault for any problems... Raspberry Pi grow computer...DIY and forums. Seems like temp/humidity/lights atm. http://www.raspiviv.com/

http://openag.media.mit.edu/hardware/ The idea is to get everyone, regardless of skill level, to become self-sufficient and grow their own food. Currently at the $1000-2000 price point. Greenhouses use $100,000 Priva software to manage operations. Grodan is releasing a $3000 version...

Adding blood meal seems to be the reason the plants aren't yielding like last run. Stupid me. I don't know if it's the K and S I've given them, but they're frostier. Chocolate rain - same cut; one is frostier and purpling Qush1 - very easy to clone. Biggest yielder (but not big) Qush5 closeup...

I see why they call it sweet tooth...I devoured two pieces of cake...because that's all we had left :)

Nirrity, hawaiian x st3 looks and smells really nice...one reminds me of boo berry cereal from my childhood. it is super fat, trichome covered, very little leaf. easy to grow. needs support! I was joking with a buddy that a cola fell down, and it was so loud it startled me :) They're at...

I've used NPK 1-2.5-1, 1-1-2, 1-2-2, and 2-1-3, and they all work well. I've used 2-1-3 all through flower, without PK spikes, and it's worked fine. I got big, sweet, fragrant flowers (thanks to rockwool as well). 2:1 P:N really pumps up the buds. Plants "time average" their feedings. They...

Sorry to hear that Seamaiden. I was also disappointed with Jilly. The one plant that didn't hermie, looked great, reeked of grapefruit, and had a weak buzz (but nice after a couple of bowls). It seeded my buddy's entire room :( My patient begged me to run Jilly. I decided to buy jack...

The last few weeks have been shite. In and out of doctors. I messed up my shoulder after xmas and now l have a hernia. It makes geoponics tricky... I'd usually prune no later than week 2, but the road kill unicorn needed a trim. Half a grocery bag later... Feedback from another grower on qush...

I don't agree that Spurr's mixes are ground breaking. Tap water has carbonates. done. pH isn't the only parameter that needs to be managed. EC is more important - it regulates transpiration. Chelated nutrients make pH even less critical. pH drifts because the plants use up ions. What's the...

I've been away from this for two years o.O Good info. First, a point about greenhouse tomatoes. They are bred for yield, and not taste. This is a necessary evil of being in the business of $2/lb produce. The gourmet tomatoes are grown the exact same way, with the same food, only at higher...

Humulon. 3,5,6-trihydroxy-4,6-bis(3-methyl-2-butenyl)-2-(3-methyl-1-oxybutyl)-2,4-cyclohexadien-1-one; alpha-bitter acid; alpha-lupulic acid. C21H30O5; mol wt 362.45...Antibiotic constituent of hops (humulus lupulus L., Moraceae). Isoln from commercial hops: Bungener, Bull. Soc. Chim. 45, 487...

There is, but I would ignore the few ppm in a tbsp of hops. My mix is likely deficient in S in the first place...especially by mid flower. 111 ppm is not a lot, especially every other watering. I opened my Merck Index, and here's what it has to say about humulon and lupulon. To sum up, it's...

This is not scientific, but still very interesting. I've started adding hops to my mix because you mentioned Canna contains hops extracts. My feed water smells like light beer :) Bayarea: Do you believe you can combine the AN yield with the EJ quality? Have you tried adding Catalyst, Meta K...

What do you mean you have leftover hops?? Don't you put them in your beer? ;) fwiw don't try chewing on hops pellets...and then make your friends try it. Hops lose their volatile aromatic compounds within days if not refridgerated. I don't know if it's these that help cannabis - at least I'm...
