I am a soon to be first-time grower in Pepe'eke'o. I was wondering if using liquid ferts meant for hydro grows is advisable in a traditional soil grow?

Welcome chocolatesteven. There is likely alot of different opinions on this- so here is my personal outlook. Normal organic nutrients in soil usually need to be broken down by the balance of mycorrhizae and other little "good guys" living at the roots, while hydro nutes are chemicals already broken down and ready to be instantly usable by the plants- but in the end hydro nutes will grow plants in soil quite nicely. If you are doing a completely organic grow, then you'll likely stay away from the hydro nutes. I am not aware of any scientific proof that organics are any better than chemical ferts, but lots of people tend to claim there is a better taste and quality of the smoke with organics. I tend to think there are alot of variables, and some of the best I've ever tried happened to be grown in hydro conditions. The best thing I'd say is to play around with both, and see what works for you and your preferences, but again, hydro nutes will work fine in soil. Check out homebrewer's threads- he mainly does ebb/flow hydro, and has recently been very happy with dynagrow products, he also does some soil grows, watering with dynagrow, and has some beautiful pics/smoke reports to support. I would never debate that one is better than the other- as it's a matter of preference in my mind, and I don't see any reason one train of thought is better than the other- they are just 2 different approaches and both grow plants. FYI- I am building sterile aeroponic system and plan to use chemical nutes, but my vegetable garden- I do keep completely organic.. ;)
 
Thanks a lot. I am thinking about doing organic ferts sometime in the future. However, this being my first grow and it being close to short season, I decided to go with the less time consuming option. Also, it's quite rainy in my area (north Hilo) and I was wondering if cloud cover can negatively affect the veg stage?

That's cool. I don't know if one is less time consuming than the other, but either way, go with this for now, and change it up in the future and compare your results. I wouldn't worry about the clouds too much. I've had some great product from Hilo- just look at all the other greenery flourishing there for evidence. I suppose constant clouds might slow down photosynthesis, but there is still alot of sun getting through that the plant can use. It will at least help the plant from not burning in the sun, which has been an issue in my neck of the sunny woods. ;) Just to be fair- I am not nearly as experienced as some of the other people in this thread, but I like to think I have good common sense, and have done alot of homework... No amount of research ever equals real life experience, however.

Fuzznuts seal the bag with the fungus gnats.... Take it back....
What store did you get it from?
Sheck - Got them from Green Hands in town. I popped one bag and filled a few buckets and am baking in the sun with a drench of Azamax. trying a little experiment to see if this approach would/will work (for future reference). I'll take the others back as I'm sure their stock has probably been cross contaminated. Waiting for new shipment of FFOF at Organic Gardening in Waialua.

Have any of you guys experimented with the TAP water on Oahu? Over the past week I’ve made two teas (Just Compost) one with water straight from the TAP and one with water from the TAP that has set for 24 hours. Both seemed to inoculate the microbial activity at the same rate. I’m assuming by the results that Oahu must have really low levels of chlorine in the water? Or at least the water on the Westside (Pearl City) does. I really have no issue leaving water in containers to dissipate the chorine, but if the chorine isn’t strong enough to kill of the micro biology in the tea I’d like to eliminate the process of storing water. Has anyone else done any experimenting like this with water?

My results agree with yours Coot... I think the chlorine (Cl) is pretty low in our water... In fact I have let water sit a couple days and I have started to see a bacterial sheen on the surface... and it will usually dissipate over a longer period of time .
I don't think you will have any issue with your teas...

You have to keep in mind that Chlorine (Cl) is an anion (non-metal (negative charge)) that will start to form ionic bonds with cations (metals (positive charge)) like potassium, sodium, iron, zinc once they encounter each other...... so once water that contains chlorine is mixed with other nutrients it will bond and you lose the chlorine .....
In most cases that chalky residue (salts) that you find in your grow containers is most likely KCl ( potassium chloride)... It's the chlorine stealing potassium from your nutrient mix and it is coming out of solution on the edge of your container...

I talked with a scientist for Board of Water Supply awhile back about that Coot, there is D12 chlorine in our tap water. Not a whole lot, but enought to make me bubble my water for an hour or let it sit out overnight before I water. I read somewhere that lemon juice will kill chlorine, but not sure. Even though I organic as can be, I still adjust the ph of my water and check the ph of my teas.
Favorite tea is: EWC, kelp, alfalfa, em-1, molasses, and maybe guano.

my bad C12, not D12. here is the e-mail....

Aloha -------. The easiest is to let water sit overnight. Aquarium folks usually do this. A charcoal filter usually works too. This is the basis for those “Britta-type” filters you often see. The activated charcoal inside is traditionally used for taste and odor removal. To kill Cl2 for lab analyses, we put a wee bit of sodium thiosulfate in samples. That puts more “chemicals” in the mix though.
To put things in perspective, while there’s standards we have to follow, we try to use an absolute minimum of Cl2 because of esthetics and economics. Except for sensitive things, like certain kinds of fish or plants or for allergic individuals for instance, there’s probably not enough Cl2 in the water to matter. For example, IMHO there’s not enough Cl2 to get anywhere close to disinfecting a decent sized compost pile. Up to you though!
Any of these sound like they’d work for you? Let me know. Stay healthy!

Interesting! I wonder if I should up the potassium a little to compensate for the loss of potassium that is being bonded to the chlorine? Maybe add a little hard wood ash could be added prior to adding the amendments? An of course I can always bubble my water a good hour before adding any amendments and not have to really worry too much about it. Either way we’re lucky to live in a place that doesn’t have poisonous water. When I was a kid growing up in SoCal there is a little slice of Americana better know as “Riverside” and you could literally chew the water, as a matter of fact you still can I’m often reminded of that every time I visit my folks

Thanks for the info man! I suppose an ounce of prevention is worth more than a pound of cure. My tea ingredients often have the same goodies in it as yours. The Kelp and Alfalfa are amazing! I’m growing a citrus hedge and I have a few lazy trees, I’ve been foliar feeding them with a mild tea consisting of Kelp Meal and Alfalfa and they’ve been responding with new growth. Can’t argue with results like that

I think your friend meant Cl2 (not C12) which is the native form of chlorine (Cl will form a covalent bond with another Cl forming Cl(2)) Cl+Cl =Cl(2)...
Chlorine (Cl) is never really on its own because once it is broken down from Sodium Chloride (NaCl), the solo Cl ion seeks out another Cl unless it bonds with another metal (like K or Na)..
In most cases the Cl ion will go for the covalent bond (where the bond is due to sharing a pair of electrons) before it will go for the ionic bond (based on electrical charge)

Cl ionic bonds..
Cl has a charge of -1 , so it will bond with elements that have a +1 charge (Lithium, Sodium (Na), Potassium (K) etc)
Cl(2) has a charge of -2, so it will bond with elements that have a +2 charge (Magnesium(Mg), Calcium (Ca)

Your friend put Sodium Thiosulfate in the water so that the Sodium would bond with the Chlorine... and it could become NaCl... that would be disastrous form of sodium for your plants....

Lol my first post-graduate degree is in Hydrogeology so I got a decent handle on chemistry :)

I understood the first sentence, kinda lost me after that........do you drink tap water?
I never drank tap water before I moved here... It's good ! Should I be concerned?
My background is more in groundwater transport with really no experience in groundwater quality

It's my understanding we have some of the best tap water in the nation, I drink it....but I drink from the streams too....

nice pile of dirt! did you have a semi truck deliver that to you....hahaha
Ha! I spent the first 4 months of this year in North Cali helping all the med growers get ready for the season, along with taking care of my plants, I worked at my friends grow shop. Talk about going threw some frigging dirt like water..... I was working and this one guy came in and wanted 90 pallets of FFOF, I was like FUCK!, your gonna be busy!!!
