thanks , i am going to go with dutch master advanced, there is a kit on ebay
http://cgi.ebay.com.au/DUTCH-MASTER-ADVANCE-NUTRIENTS-1L-NUTRIENT-KIT-/230597922268?pt=AU_Seed_Starting_Hydroponics&hash=item35b0b50ddc should that be all i need to get started in a bubble bucket?
That kit would be a bad purchase...
Silica is optional. It will make your plants bend without breaking, and help them resist stress, but that's about it. I don't use it.
Zone is used to sterilize the water, but since I use beneficial microbes I can not use it. I have used it in the past and it is a great product, but did not keep me from getting brown slime algae. To be fair, none of the other many sterilizing products I tried would kill brown slime algae either, which is why I switched to beneficial microbes, and have been extremely pleased ever since.
If your plants do not spend much time in veg, you don't need the veg add27. I use only advance for my two week veg, and the plants are beautiful when they enter the flower room.
I recommend getting the advance veg A and B, which cost $10/liter. (both included)
I recommend the gold range flower A and B, which is $16/liter (both Included)
I recommend the Add27 flower, which is $18/liter
So 10+16+18= $44 + ~15 shipping = $56
I also suggest not using a huge res, or you'll be wasting nutes. I like 1 1/2 gallon of water per each plant sharing the res. If you used a 20 gal res like some, it would take nearly half a bottle of dutch master nutes to fill it just once. Using 6 gal buckets (5 gal water) and changing nutes every 7-10 days, one 'round' of bud nutes will last me about 1 and 1/2 grow cycles, veg much longer.
With the money you save you should purchase Dutch Master liquid light, which is a foliar spray that puts your plants into overdrive, I spray every 3rd day. I also highly recommend the Saturator, which can be combined with any spray to make it more effective. These sprays are what help me get better yields than my friends who also grow DWC. Liquid Light + Saturator combo is about $60. I have had my bottles for just over a year and they are just under half full.
To give my foliar spray a boost I also use a product called snow storm ultra. This encourages trich production. A small bottle lasts forever, you only need a few drops in the with the liquid light + saturator.
Using the system I described above I am able to get very nice results, such that other growers often ask me what my secret is. All Dutch Master products have an indefinite shelf life.
Lasty I would recommend using some sort of beneficial microbes. Aquashield + ZHO powder is pretty cheap yet still very effective.
This is where I get my nutes. Shipping takes about a week.
