how many liters of nutes to buy ?

I am going to be starting a RDWC grow using these buckets.

My question is how much nutrients will i need to buy for the whole grow? i want to use the AN sensi grow and bloom line. would 1 liter's bottles be enough ? or should i just get the 4 liter? forgot to say it will be 6 buckets with a 7th as a control bucket.

Id recommend that you save your money and go with dyna gro. Only 2 parts total, and good results on par with AN. Especially if youre using that big of buckets.

Get a quart of each and theyll be $20 a piece. Gallos arent that expensive either if you like it and want to stock up. Use the grow during veg and the bloom during flower. No need to transition.

Ive only used it in soil so im not sure of its stability for hydro but i would assume if you can ph it will be fine. Its pretty well concentrated so a little goes a long way.

calculate how many total gallons of water to be used initially and throughout the cycle, add 50 gallons to that to compensate for water uptake then calculate your nutrient usage for cycle and round that off. for example.. It takes 95 gallons to fill my system in one of the rooms,with a drain and refill midway for another 95,the 50 -100 water uptake and my nute usage @5ml average per gallon so for ea cycle I run through it, I use about a gallon ea of house and garden aquaflakes a and b and so forth with my other nutes.. nothing sucks worse than running out at a crucial time or when you need it most.. always buy more than you think you will need when it comes to your garden..never know when it will come in handy

Use there online calculator an then half it an u will have plenty.

They strong nutrients don't need what they recommend.

I was looking at the online calculator and it was close to 4 liter's for the grow but when i was looking at the feed schedule it did not look right because it was the same amount for all the weeks and does not say what the PPM would be. I think i will just go with the 4 liter and if i need more buy more. I live in SoCal so a store is always close by.

Hit print out page an shows yeah sure says ppm of 1080PPM

That burn most strains in DWC.

I've never gone over 7/800 ppm with 4/5ft size plants.

I'd love to see the strain size of a plant that take that amont
