I'm not in Toronto or the GTA but we use Homegrown Hydroponics here in Barrie. DH works in Toronto and went to the HGH store out by the airport. He says it has more supplies and part of their store is set up with grow stands etc. I would recommend them. BTW, the people who work there also use hydroponics.

I am a newbie, my interest in hydroponics began 4 weeks ago when I was given an assignment in a classes at the Community College. We were told to use what was available to us and not to go out and buy something. I did some research and decided to try and grow some vegetables using hydroponics. I built an ebb and flow system which turned out great no problems. I also built a NFT system using 2 old rain gutters to grow different varities of lettuce. I like the idea of the 5 gal buckets for individual plants what type of system are you using in those?I haven't planted tomatoes yet, I didn't have room for them. I think I'd like to use the 5 gal buckets can you e-mail me the info. donnie1354@hotmail.com

as usual I am the first one to comment on my own post lol after a lot of research in Pythium. this nasty stuff are not easy to get rid of .. for a complete disinfection I have to disassemble my setting and disinfect all the nooks and cracks. I see inside the tower I have brown slime build up on the inside walls .. Pythium biofilm I highly doubt that would come off by chemicals.. I need to get in there and cleana nd also discard all the plants and start over.. man that takes too much energy and time that I am not up for .. not today lol

I have 6-12-28 from vertigrow http://vertigro.com/ I bought 25 lbs of it. I really like it. Its an all purpose formula. Now of course you could get some from chem grow which has very specific formulas for exactly what you grow .chem grow hydro grardens for example this shows a cucumber formula. they have all the formulas customized for what you are growing.
