Slow release Nitrogen?

Ok so I'm looking to supplement my soil with a nitrogen source that is slower releasing and will last longer into flowering? Anyone have any ideas?

Bone meal(N and P) or Blood meal(just N). Both are good choices. Feather meal is another great choice but can be hard too find.

thanks homie.............

Mexican Bat Guano.

Can you get 3-4 month osmocote and put it on top of the soil. This stuff is unbeatable if you want slow rel fert. To give you some idea my local produce store has it for $180 for 20kg the next best fert is $40 for 25kg.

Buds is right. The original Osmocote has been a long time(40yrs+)player in the growing world. And a few years ago they gave us Osmocote Plus, absolutely amazing nutes to grow with. A bit of a learning curve but worth the effort IMO. It will give anything Advanced Nutrients has to offer a damn good run for, well I cant say money because we all know which one is cheaper, yield and over all vigor of your plants. Any grower should play with it. But especially the outdoor guerilla grower, its a hidden gem.....

No problem. The two biggest things I want in my mix for flowering is Kelp Meal and Rock Phosphate. Those 2 things along with some worm casting will do you right...

you guys are awsome...... much appreciated

blood meal is for FAST release! I use guano or something like alfalfa meal or even crab meal is good.

Osmocote is a good slow release source of N. It is derived from a polymer coated ammonium nitrate, ammonium phosphate, and some other stuff along those lines. The Osmocote Plus is basically the same thing with micro-nutes. Temps have everything to do with how quickly it releases. Cold temps it can last 6+ months, and high temps can reduce that to 1-2 months. It is available in small to large quantities.
Nitroform or sulphur coated urea are slower release sources of N with SCU being the slowest of the two. You may have to buy larger amounts though. I get the stuff in 50 lb sacks. Temperature has a similar effect on the release rate.

well one of my strains is a N HOG until about the 4th weeks into flowering and would like to supplement. Its a bb cross so when flowering it has to produce hundreds of smaller "bud" leaves and If I don't feed heavy N at beginning of flowering she will eat herself very quickly.. within days..

I find foliar feeding with fish emulsion really helps me over the hurdle during stretch and into flowering. I have an El Monstre X Sannie's Jack and really can't believe the amount she consumes at least twice as much as anything else I have growing presently. The fish emulsion is only 5-1-1 so I usually add seaweed extract to bump up the P & K while they are in flower.
I have been trying a few new things to keep the girls greener going thru this stressfull time and have found the fish emulsion and an amino acid based nute which is 5-7-9.5 which also does really well but is a bit pricey. I can't honestly tell the difference between the two but I love the fish emulsion as it also has so many trace nutes and minerals in it, also its antifungal properties help on mold problems.
Hope this helps

I actually have a bottle of that neptunes harvest or what every it's called, I usually hit them once a week foliar feeding with fox farm grow big but I might give the other stuff a shot.. I bet alot of people would have alot less problems if these fert companies would tell people the right time to start using them.. Advanced nutes will tell you to start their sensi bloom the second you flip the lights but if you do then you will run into the typical N def in week 2-3 of flowering

Yes Blood Meal is fast release, but it does not break down and release all at once. The rate it is available is related to temp, moisture and biological activity in the medium. A tablespoon per gal of medium will feed about 2 or 3 weeks, enough time for the Bone Meal to start kicking in and taking up the slack.....and I agree the guanos are good also. But in my opinion their major benefits is the biological activity the offer. One of the greatest joys I get out of growing is trying different mixes and amendments.

I think Fish Emulsion is the easiest way to tend a plants N needs during flower if you nute lineup is falling short on N.

totally agree.....

neem cake?
also keeps soil bound bugs at away.
Neem Cake has an adequate quantity of NPK in organic form for plant growth. Being a totally botanical product it contains 100% natural NPK content and other essential micro nutrients as N(Nitrogen 2.0% to 5.0%), P(Phosphorus 0.5% to 1.0%), K(Potassium 1.0% to 2.0%), Ca(Calcium 0.5% to 3.0%), Mg(Magnesium 0.3% to 1.0%), S(Sulphur 0.2% to 3.0%), Zn(Zinc 15 ppm to 60 ppm), Cu(Copper 4 ppm to 20 ppm), Fe (Iron 500 ppm to 1200 ppm), Mn (Manganese 20 ppm to 60 ppm). It is rich in both sulphur compounds and bitter limonoids.
According to research calculations, neem cake seems to make soil more fertile due to an ingredient that blocks soil bacteria from converting nitrogenous compounds into nitrogen gas. It is a nitrification inhibitor and prolongs the availability of nitrogen to both short duration and long duration crops.

I use alfalfa meal and soybean meal for slow release N. Both are good for ~6 weeks.

Alfalfa can really heat up your mix, enough to burn roots if you're careless. I just mixed up some alfalfa, soybean and castings for a top dress of some long term plants. The following morning I went out to give it another swirl and damn near burnt my fingertips! It was that hot, well over 100*. This was ~1 1/2 gallons in a 5 gal bucket.

I use the soybean at ~2x the amount of alfalfa, even though the soybean has ~3x the N, because of this and I've learned to not use more than 1cup/cf. LOL

Wet

well wet remember how I thought I was having a magnesium def using the promix with my bb jam strain... come to find out it wasn't that at all, I was cutting the nitrogen out waaaaaay to early into flowering (ya i'm an idiot lol) This strain is a complete N hog, doing a couple of test plants cause I was fed up and about to kill off that strain (which is hard because I've had it for around 5 years) then I said fuck it and hit them with monster amounts of Veg food the first 4 weeks into flowering and god damm NO ISSUES anymore... I am honestly amazed at how much nitrogen this plant eats during flowering. I have been feeding them EVERY OTHER DAY with double the recommend amount and they are LOVIN it so i wanna see if I can supplement my soil with added slow release nitrogen.. and come to find out that was the only problem I was having... Ya I think I smoked myself retarded because it took me almost 2 years to figure it out
