First of four new systems
I just finished the first of four new systems. This one is a drip system with 4 Broccoli plants. I got everything I needed from Lowe's hardware and Walmart, except the pump (I already had) and the growing medium.
5 gallon buckets $2.34 ea x4 $10 through holes (bulkhead fittings) $1.97 x4 $8 spray paint, 2 black and 2 white $.99 ea $4 1/2in vinyl tuning $9 one size larger than the 1/2in vinyl tuning, 2ft $2 storage container for reservoir from Walmart $3.50 furnace heater filter, to keep the growing medium from going down the through holes and clogging $2 Total $38.50 I will be changing the rings of clear tubing to black tubing shortly. I just used the clear for now because I will be building 3 more hydroponic systems and was not sure if I had enough black tubing for the others, so that is just temporary. It took a little thinking and adjusting to get them all to drain back to the reservoir properly but I finally figured it out. Two problems with that were the angle of the tubing needed to be a genital sloop back to the reservoir. The other was by just placing the ends of the tubing into the nutrient solution some how caused air pockets in the lines, that caused it to stop flowing. I used some tubing connectors I had leftover to connect the ends to P.V.C. tubing then down into the top of the reservoir. I will be growing a total of 7 plants in 4 different systems: Broccoli Tomatoes Butter lettuce Spinach Peas Snow peas Green beans Last edited by GpsFrontier; 10-12-2009 at 07:52 PM. |

nice and it has given me some ideas. A bit off topic but can peas and other legumes be grown hydroponically? I am sure in science class many moons ago we were taught that legumes get their nitogen source from a symbiotic relationship with bacteria?

I don't know of anything that can't be grown hydroponically (I am not an expert though). Even trees are grown hydroponically. As far as the nitrogen it is in the hydroponic nutrients already, and in a form that plants can drink up. I will be growing green beans, peas and sugar snap peas hydroponically as soon as the seeds sprout.

Just thought I would post an update. The broccoli plants are doing great. They are 3 weeks old at this point and growing rapidly. I would have taken pictures earlier but the backyard was a mess because I have been working on the other systems.

Well it's been about a month and half now sense I started the broccoli plants, so I thought I would post an update. I noticed broccoli flowers coming up about 3 days ago on one of them so I checked and all of them have them coming up. I look forward to making my signature broccoli cheese soup with the first heads.

Thanks
Seeing that broccoli gave me the inspiration that I needed to put my idea into motion. I wish I had the room and a space outdoors.

I like the "ring" of water hose around the plant. I assume there are multiple pinholes around the circumference to water evenly on all sides. All in all a very nice looking system and I look forward to future updates!
I am using 1/4" soaker tube connected to the "T" connector inside each grow bag in my system. Last edited by TTRgreen2010; 01-17-2010 at 10:09 AM. |

I was worried that it might not water evenly with the rings so far away from the base of the plant, but the timer is set for 1, to 1 and a half hours on at a time, and they have been doing just fine in the coco chips with moisture. In fact there has been a few times that the breaker would trip (because of a power strip I was using) and I wouldn't know about it for half a day, I never say any wilting in the plants. Quote:
I have had these pictures for about a week now but I am just getting around to posting them. We had about 4 days with rain, one day it rained all day. These pictures were taken just before the rain. The plants seemed to do fine in the rain. I was worried that too much rainwater would get into the system and overflow the reservoir. It did fine until the last day with rain all day. Enough water got into the buckets and then drained down into the reservoir to overflow it. I had just changed the nutrients right before the rain. After it overflowed I just added some nutrient concentrate to the reservoir, so I don't really know how strong it is. I have harvested many more heads sense the one I posted, but so far the first head from each plant was the biggest. I think mainly because that is the biggest steam on the plant. Nothing has grown out of the part that was cut yet, but I am getting many smaller shouts with florets on them. They taste just as good, just smaller. I need to cut them off before they flower so unfortunately they don't have the chance to get big. You can see a flower starting to open in one picture, I should have harvested that one a few days earlier (I harvested it right after taking the picture). I am really happy with the way this system functions so far. I have done some minor things to the tubing at the bottom to make sure there is no leaks where the tubing connects to the bottom of the buckets. Mostly where the two different size tubing connect, I basically just glued them together with a water proof flexible glue. Once I changed the nutrients and accidentally knocked off the tubing from one of the buckets and didn't know about it. When I came back to check the pH level 3 gallons of my fresh nutrients was on the ground. I zip tied them on to make sure that wont happen again (so far so good).

I am sorry if I missed this but GPSFrontier what is the medium you are using on this system?

The bottom third to half of the buckets are filled with cleaned and sanitized rocks from the backyard (to take up space and cut down cost). The rest is Coco chips.

How do these compare in price to hydroton?

The coco chips that I used were $9.95 for 4 cubic feet (picture attached). I'm not sure how much that breaks down to in liters. But if I remember correctly when soaked it to wash it, and it was fully expanded, it almost filled the 18 gallon storage container that I was using. There are just over 4 liters per gallon. Though the coco chips are not reusable, and the hydroton (grow rocks) are reusable. I don't know if shipping is a concern to you like it is to me because we don't have any hydroponic stores here in town, but I think the weight was about the same for the 10 liters of grow rocks as it is for the 4 cubic feet of coco chips. I just look at the "contact us" information on the website to see where the place is located, and I try to order from somewhere close by. |
