Hi UG,

 

  1. If you remember the setup by GG on GTI GHW he has made holes under the growbags and let the water drip onto a plastic sheet. Would it be possible to connect a pipe nipple or something similar like you have done with your Pot outlets to the growbag and ensure there is no leaking? I like the idea of being able to pipe the outlet water back into the reservoir as this removes the possiblitlies of contimination of the solution.
  2. I notice that you have left the cocopeat in the pots exposed to the elements. Doesn't the water Nutrient Solution (NS) get evaporated due to the Sun? Doesn't your pH and EC go haywire after a few days? May be I should wait for the hot Delhi summer to know if it matters or not!
  3. Don't you think you are over crowding the tomato plants. I thought it would be ideal to have one plant per pot, don't you?
  4. Where did you get the strawberry runners from? Are you using different NS for each of the plant types (Tomatoes, Strawberries etc)?

Thanks,

Srikanth

Srikanth,

 

As I promised earlier, here are the PVC take out images.

PVC Take out Lead.       PVC Take out lead with size comparison

Make a hole in the grow bag about little less than a centimeter. Push the washer along with the nozzle. You might want to add some glue or silicone to keep it leak proof.

Hope this helps

Thanks GG !

Hi Srikanth,

Sorry for the delay buddy. Please find below the approximate prices of all the items: 

 

Joint                     – Rs. 7

Tee Joint               – Rs. 7

Tap Joint               - Rs. 7

Elbow                    – Rs. 7

Spaghetti Tube      – Rs. 8 / mtr

1/2" drip tube        – Rs. 20 / mtr

End cap                 – Rs. 6

Connector              - Rs. 7

Emitters                 - Rs. Rs. 5

Stake Drippers        – Rs. 8

 

What is the submersible pump capacity you are using? - 

    Voltage: AC 220 V, 50 Hz
Power: 18W
Max Flow: 750Lph
Max Head: 1.5Mtr(5ft)
Outlet Dia: 8mm(0.3inch)

 

The question I now have is if the 1/2" drip irrigation tube/pipe will fit over the 1/2" threaded outlet of the tank nipple. In other words, I am wondering if the drip outlet pipe will fit the tank nipple outlet. – Have used the heat expansion method successfully , took hot water and emmersed the tube / pipe in it and inserted in the tank nipple with a little effort and secured it with a metal clamp.(Do let me know if  I understood your concern correctly)

 

Hope this helps you.

Happy Growing !

Hi UG,

 

Thanks for the details.

 

I had a guy who installs Drip system very close to my house. He stopped by my place and said that he will be able to supply high quality material (Company: Harita :http://www.harithaagri.com/ I only heard of Jain before). He quoted a price of Rs 10/m for the 1/2" main pipe and about Rs 2/m for the 6mm pipe. About Rs 5 for the Tee and elbows.

 

He said that he will be only charging fixing the drip system and also indicated that as my requirement is only a hoobby/experiment he will not charge more than Rs 500 to 1000.

 

One point that caught my attention was that most stores in Hyderabad (in Raniganj area) only sell local material and that too in 300 m lengths. As this guy does installation on a regular basis he would be charging me only for the material used.

 

Yes, you got my question regarding the tank nipple and the drip pipe correctly. I think I too will be able to use heat expansion technique.

 

Thanks,

Srikanth

There is another reducer adaptor to connect the tank nipple to the drip pipe. Go to a drip irrigation shop and ask him to show reducers/adaptors.

Hi UG:

Have been trying to contact you desperately to seek your help! I am also in Delhi and would be highly obliged if you could kindly let me know the dealer from where you buy your drip irrigation requirements. I must set up the system before the onset of summer. Kidly do help.

Hi UG,

 

Not yet. GG had sent me pics of a PVC takeout lead. I need to check if it is available in the local market. I will resume construction of the garden next week.

Hello GG, 

 

Where can I source the tank nipple from? I did go around asking for this in various hardware shops in BTM layout. I had tough time explaining the need and some who had tank nipple it was with 1'' dia and cost 40 Rs.

Hi STS,

 

I could buy this in Hyderabad for Rs 2.80. (100 pcs at Rs. 280). It is sold as parts, the take out lead and  the 12mm rubber bush (not sure of the exact terminology). I download this thread on my cellphone and showed it to the dealer who gave me the parts.

I fixed it to the growbag yesterday without the glue and there was no visible leakage. I will add silicon glue for safety. I am waiting for my 80 growbags to arrive by TCI courier.

 

I do not think it will be available in regular hardware stores. Instead you should try for it in hardware stores that stock drip irrigation products. I bought a PVC 1/2" tank nipple for Rs. 20. It is made by Finolex. It should be available in plumbing stores that deal with finolex products.

 

thanks,

Srikanth

Hi GG,

 

Yes I am very relieved that I was able to source it. Now I am suddenly faced with the prospect of being able to setup a veggie garden of about 300 to 400 plants. I am now beginning to wonder what I have to grow. It is difficult to source seedlings in Hyderabad.

 

You and UG have been very helpful in answering all my queries. May be once my veggie garden is all set, I can invite the Hyderabad forum members for a visit.

 

Thanks,

Srikanth

Srikanth, 

 

Thanks for responding to my query. Yesterday I took a printout of the image to a shop selling plumbing/painting accessories and managed to get the pvc lead, not the rubber bush though. Will keep probing! Should have it all this week.

Great to hear that things are falling in place. 300-400 plants would supply you and your family through out the year for most of your veggie needs if not all.   Do plan it well.

Sourcing seedlings? Why not grow your own? It might be a lot cheaper too. What say?

In my end, my garden is in not so great shape. Intermittent rains and health issues put garden in the back seat. But getting inspiration from all of you now.

Have planned some stuff for this weekend. Hoping to catch up with you all.

 

Good luck.

Hi STS,

You are in Blore right?. Go to SJP road and every store has this Takeout-lead plus the washer. They are  a set(sometimes sold along with endcap).. If you are not from B'lore.Ignore this.

Do update your profile with your location so that its easy to guide.

It is just that seedlings are a shortcut. Not all seeds are germinating. I have this strange problem of ants eating into my seeds/seedlings in the seedling trays. I am using 2:2:1 ratio of vermicompost : Cocopeat : Neem Cake.

Do Spinach transplant well?

Totally agree with the shortcut part. It gives a jumpstart. For Ants, I keep the tray and around it, I draw a line with Laxman Rekha (cypermethrin chalk).

If you grow spinach in small cups and plant them without disturbing the root soil/media, they will pickup. That will be too much labor though. I just sow 2-3 seeds per hole and thin out the excess. For seed starting just cocopeat is also fine and covering the tray with polythene also keeps ants away but again depends on how big the tray is.
