Hey everyone, I have been growing in dwc for many years now and am about to start a 10,000w DWC bucket grow so I am doing some major sharpening of my skills and wanted to start a dwc nutrient thread as it is one of the darker areas for me.

Cheers.

What are some of the feeding schedules used by some of the successful dwc growers on here?.
Do you guys use half strength of the "Gh feed chart"?

10,000 watts? Why not use the schedule offered by your nute manufacturer? Many use the Lucas formula.

Alright here we go, the Lucas formula?... I do use the schedule offered by my nutrient supplier and have used the schedules offered by many nutrient suppliers in the past 10 years but I just wanted to know what everyone else is doing. For homework purposes...

And yes.. 10,000 watts. More light = More bud...

I disagree with the lucas formula, and im currently using it. It has half or 1/3rd the level K (potassium) which GH recommends. i hear will mean a potassium deficiency if you leave the plant to veg too long. Apparently Lucas only veg's for few weeks so hes off to flower fast.

Alot of people use the Lucas formula for FLOWERING i have yet to get that far with it but I will be trying it!

I am currently using week 2 of the GH formula, Its at 380ppm and next week ill gradually raise it to week 3 limit.

Id recommend you start simple as fuck your first go, there are so many ways to screw it up. I was having so much trouble with my plants because my humidity was too low. EVERYONE was telling me humidity is bad, the lower the better. Well I come to find out that plants in veg love a humidity of 60%. I have trouble maintaining 40% right now but even at that level my plants are recovering fast.

good to know that lucas comes up very short in K. My blueberry plant had K deficiency in weak and brittle stems and is super pissing me off because of it!#@!#@!#!@# lucas fail mula. ANyways I upgraded my nutes weeks ago my deficiency was more because of the pH, apparently it needs to be below 6.0 or else K gets locked out.

but my plants were generally healthier using technaflora's full line than the lucas formula, as one could only come to expect... and plants I've seen flowered with the lucas formula could stand some better nutrient regimens... I only used it for veg, but I wouldn't use it again... its just cheap and easy.

See on the GH website, it has two programs - drain to waste and keep it recirculating... what do we use as dwc users? Cheers!

well recirculating is hydro style and drain to waste is soil style although either could be done either way. use your intuition and be creative :idea::idea:

I think doing recirculating but weakening it to like 80% or so would be good.

Id like to know what people think about organic nutes and feeding in DWC. I have been using floranova and on my last grow I acheived good results with it and I could push the ppm without any burn I did get the claw effect though. I was told by the guy at the hydro store that it is impossible to burn plants when using organic nutes, how much truth is there to this? this time around I am not having such luck as the last grow, I am encountering a variey of issues whether or not they are nute related I am not sure, but I have heard that organic nutes are only good for so long on the shelf and it has crossed my mind that this could be part of my problems.

I did GroTeks line of all in one Hydro Organic nutes for a few rockwool slab tables and it produced some amazingly large buds.
There is the worry of your nutrients going foul while they sit in the reservoir for the week or so before you change. I have always found that non organic based nutes always do better in hydro setups and I like to use hydro\organic nutes when the medium is something that can hold some moisture like co-co or rock wool.

I use rockwool cubes, and I also thought about how long organic nutes were good for. in the summer when I first started using the floranova it was real thick and now the bottle that I have open and the unopen one are a lot thinner or seem to be almost watered down. do you think that temperatures would cause this.
