the pump my dad has is quite large, I did some searching, and was wondering, I found a 55GPH pump.. that would fill the flood table in about 10 minutes, would that take too long, do you want it to fill rather quickly?

I can buy a more powerful pump, but 11.99 is definately in my price range :)

Upon some research.. that pump of my dads is at least 1260GPH :shock: .. seems like overkill...

That is a large pump. I'm not sure the speed of the fill matters, but how long the roots have to absorb the nutrients. Too long will begin to dron them, too short will starve them, the rate of fill is likely not a big deal.

I am no expert though!! Anyone?

Ok well at 55GPH thats something like .92 Gallons per minute, so it would take about 10 minutes or so for the flood to reach the roots. So if I set it for about 15 to 20 minutes? gives it 5 to 10 minute soaking? Sorry, I understand you're new to this as well, but maybe together we can figure this out :) Oh well, trial and error, guess there is a good reason lettuce comes with like 3000 seeds in a pack :)

Mine takes about 3 minutes to fill and holds that for the additional 12 minutes of the cycle. The plants are rooted in root riot plugs which are absorbent.

They get 3 full hours between drain cycles and I have noticed the rocks are still moist at 3 hours. Not wet, but moist. I assume the root riot plugs are well saturated. The overnight dark period gets one cycle and I have noticed no ill effects or signs of over or under watering.

I think I picked up the fill and drain cycles on line somewhere (probably here from one of the experts), and only tweaked it slightly.

Not meaning to jack your thread here halfway, hope you don't mind.

'87, stay with your small pump. It will do just dandy for your size tray. The flood trays I run are 2x2 and they have 144 gph pumps in them. That big pump would work you'd just need a REALLY big overflow/drain line for it. Most guys flood every 3 - 4 hours lights on and once during the dark cycle. As long as the plants get soaked for 10 minutes they'll do fine. A 30 minute soak will not hurt them at all.

Don't lose any sleep over the air pump. Simply not necessary when running flood drain systems. I've got some laying around but only use them when running DWC (continuously submerged roots). When your systems drains fresh air (O2) is pulled into the tray which is plenty for your plants. Running a pump sure can't hurt a flood drain system but it isn't necessary.

Thanks hydroguy, unfortunately the home depot here is out of pumps for the season, next best i could find there was 90 bucks. So I'll check Home Hardware tomorrow, they have the same 55GPH pump there for a dollar more.

All I need now is the pumps, pipe, and to finish building my light fixture

No worries hydroguy, plenty of good info on this thread.

I noticed the box store pond pumps were very pricey. You may want to look online at a hydro store. My submersible is 265(ish) gph and less than 20 bucks. It came with adapter fitting and had good reviews. It seems like lowes and hd pumps were all 40 plus for 2-3 head height. I guess pond shoppers can be fleeced, LOL.

Hmmmm, what to do with all these micro LED Christm,as lights I got for cheap??

got everything I need, I will build it tomorrow while I got the day off for Remembrance Day, ended up getting 2 pumps from the hydro store here, for the money, they are good pumps, actually I accidentally picked up 2 different size pumps, a 264, and a 392 GPH, oh well, I'll build and set up the 264, for testing, the price difference between the 2 was 3 dollars.

Thanks for the inspiration for starting this project Halfway! :D

I think we have the same 264 pump!! Get some pics posted.

My plants are outside the rim of the pots now. Phenominal growth!!! We added a little lemon basil to last night's dinner. Store bought cannot even come close.

I am thinking of adding another sterilite the same size as my current fill tray and use it as a DWC.

My concern is that the small capacity will allow easy imbalances of nutrients. The container is 28 QT, but I would only fill to approximately 20 QT.

Thoughts on a DWC with only 5 gallons of nutrients and 6 five-inch pots for lettuce?

well, I just need some pipe and a couple holes drilled and I've got one down, The big pain was cutting the holes for the net pots, for 1 of them I might go with 4 6 inch pots spaced out a bit for peppers, and keep the 6-5" setup for lettuce and herbs, we'll see, got some seeds on order, I have tons of varieties of pepper seeds, but only 1 lettuce and 1 basil.

I will still need to hit up Wal-Mart for Bulbs and a timed powerbar for the lights.

Just looked up DWC on youtube, simple system, seems as though if you had the roots soaking all the time, you would want a weaker nutrient solution, but the air stone should keep it well mixed, much like when adding coke to rum in a glass, the CO2 mixes the drink and there is no need to stir

anyways, here is the pump i bought, and the store I deal with locally

"87 that's one of the brands of pumps I run. Dependable little pumps, use their 396 for transfers. Via Aqua is another decent pump for hydro. Here's a link to a timed power strip for comparison if you haven't already purchased one. It's got 8 outlets, 4 run on the timer and 4 are continuous. That's the hydro store I purchase most of my supplies from. Prices are maybe 5% higher but their packaging and shipping are top notch:

Halfway, DWC rocks! Has a couple of issues with management but it sure can produce some crops. A 5 gl. bucket for lettuce would be perfect, go for it. Ran some back in the day and found a few things you can do to them if your interested. Here's a link to a lid that would be a sweet match for a bunch of lettuce plants.

Best of luck to ya both,

well.. here it is.. well half of it..

[img]https://i487.photobucket.com/albums/rr235/binchnunker/Garden%20Pics/IMG_9699.jpg[/img]

I need longer chain.. or something to place the tote on. I put some hydroton filled pots in it for the pic, 1 even has a Tabasco(Short Yellow) plant in it :)

I was having issues with the water spraying up through the handle of the tote and leaking all over the floor, so when I was out buying my lights i stopped in at my shop and built these:

[img]https://i487.photobucket.com/albums/rr235/binchnunker/Garden%20Pics/IMG_9698.jpg[/img][/url]

I will be adding a few more peppers in shortly (When they germinate) and.. when my seeds get here I will do some Amethyst Basil, and some lettuces (Skyphos, Green Oak Leaf) Epazote.. well I'll figure it out.

Video Update

Here is the latest video journal entry to the blog. Thanks for everyone's input, it has really lessened the learning curve. I am very pleased so far.

The roots are simply amazing.

GDay halfway,

great video and those are some amazing roots..

Nice little setup you have there too.. Did you make that yourself or is it store bought? Unfortunately, we don't really get many premaid flood and drain systems such as yours in australia :(. most people just DIY them.

Cheers from Brisbane Australia

Hello Danielle....

YES. Totally homemade and as cheaply as possible. I want to learn as much as I can and I feel that doing it myself enhances the learning.

I looked at several retail systems on line for reverse engineering and design, but to be honest, most of the ideas come from individuals posting homemade systems on forums such as these and on youtube.

I am still researching and drawing plans for my next phase.

Are you running hydroponics? If so, what are you growing?

The above photo was taken on November 27th. This is after many harvests which have kept it and the basil trimmed back.

We are at day 27 days (in the photo, 36 days as of today) in the ebb and flow system and this has produced many salads and BLTs. Probably $10 to $15 in lettuce. We have used several batches of basil and have quite a bit in the freezer as well.

I am building 2 DWC systems to allow continuous harvests of lettuce. I'll post when I get it up and running both here and on the blog.

Thanks for all the input from many folks....this first run has been exceptional in all regards and I learned and confirmed alot!

Looking good Halfway! Enjoy watching the vids buddy. I tried running hydrogen peroxide in my systems once and the results were frustrating, to say the least. Have no idea why as many folks use it but not heard of any one with the nute line I run doing it. Slimy crap built up all over everything in the resv in a matter of days. It is great for cleaning which is where I use it, ran out and have been meaning to get some more.

Pulled some leaf lettuce from some plants under the floro's last night, impressive. Probably wouldn't have tried it until I watched your vids, great work!

On the hydrogen peroxide, the folks using it (I'm still looking for the threads/articles) had seen prevention or even treatment of some issues and it seemed like a good preventative. I have not seen any negative changes in anything, so my use is not real scientific at this point, LOL.

Glad you have some lettuce moving. It has been productive during the learning process to actually recoup some initial startup costs with great tasting greens.

Post some shots. 8)

The first run is now in the history books!!

Thanks for everyone's contribution. The learning curve would have been MUCH steeper without the great posts and comments on these boards.

I posted the latest video on the blog as well as some commentary.

I tore down the ebb and flow yesterday ending an incredible run for the Simpson lettuce and lemon basil. We estimated 60 full salads worth of lettuce and probably another 20 batches for sandwiches. The basil is loaded in the freezer and will be used for the next several weeks in stews and soups.

I ended up cleaning the system with 3/4 cup bleach per gallon of warm water. I noticed some "slime" on the inside lid of the reservoir and the intake/outflow tubes, but it was minimal and really the only thing that looked like it needed cleaning. I wiped down the big pieces and rinsed and soaked the small pieces and rinsed.

I soaked the silica stones in the bleach water, rinsed, and now letting dry to get rid of the small pieces of roots. I intend on thoroughly rinsing again in a few weeks after the root pieces have crumbled to dust.

Couldn't agree more. I learn something each time I annotate or read previous entries. Info that seems committed to knowledge NOW, was completely foreign not too long ago.

Nice website by the way, very informative.

Fine grow Halfway! I agree with ya about the slower growth in DWC during these colder days. You thought about adding a heater to your resv? Still confused how your Simpson grew just like it is supposed to compared to how the plants I grew did.

Awesome work for your first grow!

Thank you Sir.

It (Simpson) did grow picture perfect. I think much luck entered into the equation, haha!

The DWC lettuce is ready for it's first small harvest. Game on!
