Expansion with aeroponics





This is my latest cloner box. Notice that I have plenty of misters in this box. This mist of nutrient rich water provides the ideal medium for rooting cuttings and also provide maximum growth for new plants. I have now been rooting tomato cuttings in as little as three days. I transplant my seedlings to a mister box in 2" netcups after the first week after sprouting. Large plants I move into a box with 3" net cups.

I have also noticed that misters in buckets do much better than deep water culture for tomatoes. I have converted most of my buckets to aeroponics now.

There are a few problems associated with the misters. They have tiny holes and they get stopped up frequently with almost anything. They are not hard to unplug, but it is messy and ot does take time. I am now building my bucket systems with 1/16" drilled holes in the pvc pipe in leau of the misters. It seems to work just as good and does not stop up so easily.

I will still use the misters in my cloning box and early plant growth boxes.

Day 28



Everything is coming along just fine.

My cloner box is clear full now. Actually there are only 4 clones in the box. Each corner has one tomato. The remaining holes are filled with seeds that have sprouted. They include tomatoes, cucumbers, and bell peppers.

The tomato cuttings were given to me by a co-worker. They had been wrapped in a wet paper towel for a day and were in poor shape. I started with 5 and was able to save 4. Each one is held in place by a neoprene plug. These are ideal for cloner cuts. I put these tomatoes in the box just two weeks ago. Today I removed one and there was a 10" root mass. It now is in a bucket by itself.

The remaining holes all have sprouted seeds. I have used Walmart polyfill in net cups for several of the seeds. This worked ok and it was cheap. However the rapid rooter cubes which is made of coco fiber worked the best. All of the rooting media was placed in a 2" net cup. Most of those seeds germinated in only 24 hours. I am hard pressed to keep up with all of the transplants.



Tomorrow I will have to start another box.

The top photo is my seed box. It is actually a Sterlite shoe box with about 2" of perlite in the bottom. I saturated the perlite with a weak solution of nutrients.
If you look closely you will see a tomato seedling that strayed from my plug. Also I have some seeds in a damp paper towel. They will germinate, but they are very delicate and have to be moved, so I decided to plant all seeds in a rapid grow plug or some other starter media.

Week 2 - New Additions








Everything is moving right along. I now have three more systems to launch this weekend. Whoops! I have actually launched one today. I created a cloner box, which was very easy to build and cheap too.

You can buy one of these units online for about $35.00, but I made mine for less than $10. All items were purchased at Walmart and a hydroponic supply house.

Sterlite plastic shoebox - $1.00

8 neoprene 2" inserts at 35 cents each $2.70

1 air stone at $1.25

Total cost - $4.95.

The neoprene inserts are pretty neat as they have a cut on one side so you can open them up and insert a stem from whatever plant you are cloning. These inserts are reusable.

It did not take more than 15 minutes to build this entire box. All I did was cut out 8 1 3/4" holes with a hole saw and insert the cloners. Cut your stems at a 45 degree angle, place in insert and then in box. Fill the box with water and add a 1/4 teaspoon of nutrients, add the airline and you are ready to go. Roots should appear in about 1 week. I now have this box filled with tomato and pepper cuttings.

My next system is an airiponics bucket system. This system requires a little bit of work, as you must cut and fit several pieces of pvc pipe, glue them together, and then drill and tape 11/32 holes and add some mister spray heads. I configured the pipes so that they would reach around the bottom of the nettie pot. When you fire this system up there is a mist of water that sprays in all directions inside the bucket.

Total cost was under $40.

Bucket - $2.50
Net pot lid - $5.50
7 pvc fitings at $.30 each - $2.10
3 feet of 3/4" pvc pipe at 30 cents. $.90
7 misters nozzles at 35 cents each - $2.45
Water pump $17.00

Total $30.45


I finally got around to shooting some new photos. It has now been three weeks since I first started my two tomato cuttings in net pots in deep water culture buckets. Today I moved them inside and applied the lights which are timer controlled and will be on for 18 hours per day.

The pic showing the roots was shot last Friday which was day 12. Today those roots are twice as large. I decided with was time to change my solution and move them inside. So this time I increased my nutrient dosage to full strength and then adjusted my ph. It is critical to adjust your ph to about 6 for tomatoes. I also measure and adjust my ppm on my nutrients to 500. My normal tap water is about 140 ppm.

I am using a control bucket where I have one tomato that I am using MiracelGrow Tomato Food. I wanted to see how well local commercial nutrients would work in my hydro systems.

I next rigged up a light that is very simple and cheap to construct. All it took was one section of aluminum stove pipe that is approx. 30" long. I spread the stovepipe and held it in place by using two 1/4" pieces of all thread and 4 nuts. I then inserted a dual lamp fixture in the top of the reflector. Next I hooked up two pieces of chain, then attached an old extension cord to the light fixture. I then added one each soft white, and daylight cfls.

Cost was about $12 for the entire fixture.

Stovepipe - $4.00
Ligh fixture - $1.50
All thread - $2.00
CFLs - $4.00

This system works great. I do not think you can tell from the photos but the softwhite bulb is of the blue wavelength which spurs vegetative growth, and the daylight is of the red wavelength which promotes flowering and budding.

When you buy these cfls at the store they all look the same. I can assure you that when they are lit you can tell the different. Both are 20 watts, and equivalent to 100 watt incandescent bulbs. You can find these clear up to 65 watt which equates to a 300 watt incandescent.

By the way, I now have my first tomatoes set on. Wasn't expecting anything this fast.

MY FIRST SYSTEM






I now have my first system up and running. It is a deep water culture (DWC). It is the simplest and cheapest system to build. It is nothing more than a 5 gallon bucket with a special lid that has a builtin 6" net pot. There is a 6" Sure To Grow insert and a air pump, air hose, and air stone.

Total cost. $20.80

5 gallon bucket. $2.80
Net pot lid $3.50
Sure to grow insert $4.00
Air pump $10.50
Air stone $2.00
Air hose 25' $2.50

I purchased all materials at Lowes and Walmart. The air pump has two outlets, so I am using it on two buckets. You could get a larger air pump for about $30 and use it on multiple buckets.

AEROCUSTOMS, A GREAT SUPPLY SITE



There is where I buy most of my hydroponic supplies. This company has excellent prices and is very reasonable with shipping charges and prompt too. I usually place an order and it is on my door step in three days. The picture is a very good cloner system which is used to develope roots on cuttings. Works great with tomato plants. This system is less than half the cost of most competitors. Or if you are like me, you can make your own system for less than $50.

SURE TO GROW, THE WAY TO GO

Sure to grow is a great site with many wonderful products and also several how to build your own videos. Check this site out as I have modeled my systems after the systems being demonstrated by Sure To Grow.

Growing Hydroponic Tomatoes



While I am busy assemblying my hydroponic garden, I thought I could wet your appetite by providing a few good links to sites with some great hydroponic basics.

This first site is execellent and is hosted by the Ag Dept at the University of Arizona. http://ag.arizona.edu/hydroponictomatoes/ There is a lot of good material on here that can easily be applied to any type of tomato gardening as well as hydroponic.
