Hello,

a quick question:

Do you think it is better to use the recommended strength of GH nutrients listed on the bottles, or the Lucas Formula?

I realize that when using the GH nutes, you have to also buy the Gro solution. And using the Lucas Formula you only need Micro and Bloom solutions.

I am just wondering what people think is a better way to go. It seems to me that using the Lucas Formula uses a lot less nutrients per gallon of water. Which makes me wonder if the recommended strength listed on the GH bottles is more than is needed?

I hope to hear what people think. I'm currently running a test between the 2 sytems (GH 3 part vs. Lucas Formula) on a couple of my girls. But I just started that today. I'd like to hear some of yoru thoughts.

Thank you,
-Snut

PS
I'm in vegetation at the moment. But I will run my experiments all the way through flowering... I will post pics when I can.

i like fox farm

I got the biggest yeild I ever had from the lucus method in a dwc.

I am currently trying it in soil. Check out my grow journal. I'm trying a few other nutes as well. Bio bizz, flora nova, miracle grow( i know)

I'll check it out. I also think that I will start one myself. I really like this site.

Thanks for the replies so far. I hope more people will continue to respond. The more responses the better...

Also, I should have mentioned that I am running a DWC system.

Hey I'm also using the three part Gh flora series and I would have to say the Grow does run alittle high in Nitrogen but can help alot in the veg. part of the grow but is't really needed in the blooming phase. That said, I would do some research and see what works for you and how your growing. Best of Luck

I am on my 9th plant, pretty new to this, but here is what have have experienced. I started out using the directions from GH, I was having issues with too much nitrogen. Once I started using the lucas method the issued went away. If you use the lucas stay away from any additives unless you have to have them. You can add something like botanicare sweet or GH flora nectar but otherwise I would avoid. My first plant was doing great under the lucas method, I added humbolt gravity and started to get burn, I noticed it right away and stopped and off a 16 inch plant I harvested over 3oz dry, all the branches were solid bud. Then my second plant I used sweet added to the lucas formula and no issues at all. I have one clone purple buddha and 2 cali orange in 12/12 now and all was great, added some kool bloom to the mix and started to see what looked like magnesium toxicity, so..... I redid the nutes and it all cleared up and looks better now. So now, I will not use any additives except sweet or flora nectar. One mistake with the plants nutes can slow the flower time down to a halt and really set you back. I am sure the right combo would work, but the lucas formula on it's own does a great job and is simple. I would rather get 2oz from a plant than maybe 20% more and not have to worry about poisioning them and delaying the harvest. I have no green thumb and only do about 15 min in a.m and 15 in p.m a day working with the plants and results have been very good just keeping it simple, plus you don't have to buy grow nutes which saves money. The Lucas method is simular to the nova series in npk #'s I think by what I seen in the store on the bottles. I am sticking with this now, cheap, reliable and the bud I have grown has been up there with the best strains I have had medically. I would never follow the universal directions on the bottles, esp when it doesn't state if it is for growing mj or lettuce.

I'm using the GH 3 part in veg right now and my plant looks super healthy and I couldn't be more happier. I mean my mother plant is absolutely flawless without any yellowing or burnt tips. I am following the instructions on the bottle and haven't had any problems whatsoever.

The only thing I don't like is the salt buildup but if you flush once every 2 weeks, you'll be fine.

I started using GH because it came with the kit I bought but I was going to change to a different nute when this stuff ran out. I was so happy with the way things turned out that I'm sticking with this stuff.

WOW!! Your girls are looking awesome!! I really hope that mine come back from the brink of starvation. I have hope, since they haven't wilted up and died... Now that I have the nutes correct, I'm hoping they come out of shock and start growing for me again. In the beginning I was seeing 2 and a half to 3 inches of growth a day. which was awesome!!!

quick question for you Petrol420: What are you keeping your PH at, and are you running a hydro system?

The beauty of the GH formulas is their flexibility. You can tailor it to your particular whims. I use the 3-2-1 formula that GH recommends for vegetative. I use the Lucas Formula for budding. I tried using the 1-2-3 formula that GH recommends for flowering but there is such a high level of nitrogen that they stretch too much. If you really want a good stretch, use the 1-2-3 for the first two weeks of flowering then switch to the Lucas formula. You get a good stretch and solid buds that way.

The recommended formulas (from GH) are generic recommendations for most plants where the Lucas Formula is designed for weed.

The pics you see are the mothers in a cheap DWC that I set up with 2 liter soda bottles.

I don't have an electronic PH meter so I use one of those cheap ones that use the vial and drops of some kind of chemical. Anyways its in the 6 range.

My tap water is PH 7 and after I filter it through my Brita, it's in the 6.5 range and then after I add the nutes, it drops to around the 6 range. But honestly, I don't even test the PH anymore since I know what's going on with my procedure and there is no way in hell to stabilize the PH. The PH is going to have wild fluctuations no matter what you do so why worry about it if your plant is looking healthy. Let your plant show you that there's a PH imbalance, not some stupid meter.
