DWC for beginners

just wanted to drop something surfed upon

Cannabis capable of greater production of this compound from biogenetic precursor CBD. The extent to which this production is also influenced by environmental UV-B induced stress has been experimentally determined by Lydon et al. (1987). Their experiments demonstrate that under conditions of high UV-B exposure, drug-type Cannabis produces significantly greater quantities of THC. They have also demonstrated the chemical lability of CBD upon exposure to UV-B (Lydon and Teramura 1987), in contrast to the stability of

Ok question, i have looked at every page of this thread and i am still kind of unsure about one thing, how far down you put your jiffy plug into the hydroton?
is it more towards the bottom, right in the middle or directly on top with just the hydroton around it to support it?
thanks rhcp4life

Depends sir on how U germ in DWC.
Sometimes I place the (SEEDLING) Tap root in a plug and put them directly into a pot flush with the top of the rock level,leaving my water level directly below the bottom of the pot and let them sprout.
Sometimes I germinate my seeds put them in a plug and let them sprout to seedling's under light before i put them in my system.This way the seedling grows in the plug alone and usually by 2 inches it has all kinds of roots poking out of the plug, then I transplant to DWC.
Leaving a lil rock cover on the plug.


Hope that helps

yeah thanks

I'm for sure going to be trying it DLs way for sure my next grow, I lost soooo much time in the seedling phase because I was trying to grow just in RW before my DWC, when I finally decided I should just put it in, it was all over, in the good way

would you guys like to suggest some diy odor control theads to me?
greatly appreciated!

So since we were discussing r.w and where it should be i have a question to ask. if a person takes an empty (empty as in no hydroton or media) net pot and places it over the oxygen solution then places r.w directly over netpot holes (would that be a good thing? yes i know that the solution should be changed before the system is sealed from light by the hydroton.

OK I am a bubbleponics newb and I have a question. I hope this is the right place to do it. This is a great thread and I have learned a lot. I have 2 WW in 5 gallon buckets. They are on week 2 of 12/12. I bought some neuts (Monkey Juice) but I found out were for coco coir only. WHich was originally how I wanted to grow but quickly learned that dirt sucks. So I have made successful transplants to my buckets. I finally found a hydro store and went there last Friday. i got the series of nuets the Bada Bang, Bing and Bloom. I changed the water on Sunday and added the new neuts. I also go a ppm meter and a PH meter. Both were great in balance on Sunday. The cool guy at the hydro store gave me a great feeding schedule and ppm measurements. This may sound stupid but my ppm has decreased by 200 in the last 2 days. I know this means that my babies are liking their food as they have almost doubled in size in the last 2 days also. Since the ppm has dropped do I need to add anything or let it keep using what it has until time to change again. i feel bad I didn't realize I must have been starving them but now they look fantastic. Thank you in advance. This has been a very helpful thread.

"A friend with weed is a friend indeed"

you can add nutes back up to your predetermined level

ok so I'm starting out from plain ole bag seed. placed 4 seeds in rw 7 days ago. the first one germinated and was popping out in 3 days. the second and third popped out on day 4 and the fourth seed popped out on 5th day. the first one of the 4 to pop out is actually the shortest at 1 inch . the second one is the tallest at 5 inches in just three days. the third one is at 4 inches in heigth and the last one is at 1 inch.

congrats, watch out and make sure they're not too tall... if your lights are far away, tey could be stretching to get there, and thats not good... means to bring your lights closer...

you actually wants your seedlings nice short and bushy

what kind of lights you got, how far away??

well thanx on the posative reinforcements in my grow. about my lights well i'm using one of those led lights off ebay...think it is the cheap 225 led light. so far it has proven great for germination as i made 100% in germination. i have it right at top of 10 inch net pot. i only have maybe 2 inches of hydroton in the bottom of the pot. i know the system is open for bacteria growth and that it will be necessary to clean it before the roots reach nutrient solution.

i have 2 soil grows under my belt but im new to the dwc thing looks vary intresting to me. looking at trying a 4-6 plant system in a rubermade tub i have 2 questions

1: whats a good air pump or a good cfm to look for.

2:what is a good line of nutes of a newbe to use on the 1st grow

thanks guys.

i'm new also and on my first grow in dwc. i have a home made dwc with a five gallon bucket , 10 inch net pot , a 10 to 30 gallon aquarium pump from walmart. Now for a big container like you r talking about might be a little different. maybe some 6 inch net pots or maybe smaller. as for the air pump as i understand you cant have too much light or air. so make the water frothy as you can get it. like i said this is new to me also so asking others is encouraged by me.

well i dont want to brag but this country cracker has a deer ham on the steam pot intending on barbeque deer sanwiches and the munchies from hell. blazin and confused eaten deer from the woods.......nothin is better

drawing up specs for a dwc hydro or aero grow, and trying to decide on a pump size. i was wondering if anyone knows what gallons/hour i would need for a drip system vs. a totally aeroponic system. i have an 18 gallon rubbermaid container i will be using for 5 plants. i had heard that you want 250-30gph for the aeroponic system, but i wasn't sure what size res. that is for as it seems a little big for 18 gallons! any and all input is appreciated!

Thought this may be helpfull here:

Felt like I needed to expand on this subject considering other growers have begun to do this purely on my rants and raves on exactly how simple this method actually is!

First U cut the plant in the desired location.I prefer the Tops of the plants themselves(Topping).If U cut the stem be sure to leave at least one node for future growth on the stem.(Future Cloning) Or future (Bud sites)

Second Be sure to cut @ a 45 degree angle with a SHARP clean knife, shears or razor. I used a pearing knife for awhile.

Third Be sure to have a cup of water handy to place the cutting in directly upon cutting. Its Best to cut in water so air does not enter the main cutting stalk.

Fourth Scraping. This is done quickly. U want to scrape at least the bottom 1/2 inch "SKIN" off the bottom of of the main stalk of ur cutting.
THIS means removing only the OUTSIDE layer of green "SKIN".GENTLY. Just be carefull.

Fifth U can place these cuttings directly in the cup of water. Although ive been experimenting with dipping them in rooting hormone and superthrive ive had awesome results in just placing them in plain water.TAP WATER.

Sixth Cloning medium. This consists of the cup and the water. I cut my cups.( I use regular red plastic party cups found everywhere !)I cut the cups to size to be sufficient enuff to brace the tops of the cuttings (SIZE of cuttings).Meaning, the upper fan leaves dwell on the top of the cut cup.

Seventh This is the last step. WATER LEVEL IN CUP. I put enuff water in my cup to completely cover the area which I scraped. Usaully 1/2 inch to a quarter. THIS water is CHANGED AND WATCHED daily.

Reason being. Cutting drink lots of water sometimes so stay on top keep ur water level consistent. Changing ur water only enstills U are taking every action neccesary to be sure ur water will not stagnate on ur new babies.

Its that simple hope this clears up things for a few people. Its very simple.

Here's some pix of some clones i cut 6 days ago in the cup right now developing root growth.

first post yay...anyways question on water do you use plain tap water?? my tap is around 260ppm

I'm new to this ...yet i read a lot on these same question's that you have also. I find that typing a question in the search engines brings up a whole world of information. sometimes it is information on different flowers and plants that i read but i do read it. I've read that chlorine isn't healthy for the plants. Now if you have a dug (cased well with old tank and water pump) that the water dont have a chlorine problem as it don't exist. I do hear that you can get too much iron or other minerals. So depending on where your at and what kind of water system you have ( city..........country) determines the questions needed to help you. So if this helps from a nebie then right on if it dont then keep on reading about your question (do you use plain tap water). i go to the creeks that are running to get my water. Of course i'm redneck as hell and climb tree's to shoot an animal..
