Osmocote Plus Plant Food: Discuss Its Use With Cannabis Here!

That's an interesting idea!
Why not try flushing with RO, and then putting a bunch of ice cubes on top of the medium? That should lower the temps a bit, and keep the nutes from dumping too fast....if indeed that's what's happening.

How hot is your room these days?

i never thought about really putting ice on my medium. i always put ice into my res before i feed so the water is cold going in, but not too sure how long it last in the Hempy bucket?

why the RO? because the ppms are lower? you dont think tap water would be better because of the micros?

the temps have been jumping round sometimes in the 90's but for the most part as of now its been in the mid to upper 80's.

hey Molotov!

With water that about pH 8, and has a ppm of 300, you can bet there's some alkalinity there.

Since perlite has no buffering capacity, I'd pH the water to about 5.9--6.1. You should be just fine with that!

Thanks Doc. I did just that. I lowered the ph to around 5.7 and my ppms should lower to around 265 after being in the res for 24 hours with the bubbles.
 
hey just to let you guys know after a few weeks of feeding my girls DM and OC+ in around 90F+, i was feeling like the OC+ was dumping too many nutes from the high temps so the other day i gave all the plants a good flush with just PH'ed tap water and they loved it!! everyone of them is doing really good.. the OC+ is doing allot better to.. the DM is still way ahead, but i will say their budding like crazy.. i am really loving these TRF.. now on i am going to flush every 1-2 weeks, my girls loved it. it might just be because the high temps i am in, maybe its different for you that have ideal temps? but just wanted to share this info with you guys.
 
So we can suggest that higher temps. 90s-100 can cause oc+ to release excess nitrogen, or other nutes? Causing a slight lag, and a need for a good flush-

Thanks for your input Irish! I am still contemplating hempy and this style, So very easy!!

Hit me journal brotha man! Exciting news up in there!

-Go

Irish, this might sound off the wall but how can you flush them if the prills are still in there. Maybe I'm having a brain fart but I'd love to know in case I have to do the same.
 
Run excess water through. If the prills are dissolved into the reservoir, or elsewhere in the container.

Just kind of like a nice bath for the roots.

That's my understanding!:blunt:

I am not 100% sure but IMO that seems to be the case in my grow.. The DM seems to be running along just fine, and putting out some serious bud formation compared to the OC+.. the OC+ are flowering allot better now, but so are the DM and the DM is pulling way ahead now.. the bud growth is just amazing!! i love these Hempy+Led+TRF combo in my grow.. i am going to save so much money with these TRF. i am sold on the DM for sure. i want to see if i can still find them at HD for around $3.00 i am going to stock up.

I'm retarded right now. I guess you just run enough water through them until the 2" on the bottom of the bucket drains and there are no nutes left in the reservoir, right?:tokin:

well its not a true flush in a way.. you will still be putting nutes in the medium from the prills. but since my temps are very high i am thinking the OC+ is dumping more nutes out then needed by my plants, so the N and stuff might be building up and slowing down flowering.. so i ran allot of water threw them to flush out anything that might be old build up and kinda refresh things.

If Dm stands for Dynamite, It is still available at Lowes and HD here. I thought about getting it today when I got the OC+.

yes in a way put their will be nutes still in their because the prills will release them when ur pouring water over them, but if their is any build up from before that the plant did use its kinda just flushing that stuff away and balancing things out IMO.. i am nute sure if anyone would need to do this if your temps were good, its just might only help in my case where my temps are very high.

yup thats what it means. the red bottle seems to kick ass but it dosent have the best micro nute profile. the Purple bottle is also doing great and has a real good Micro nute profile, the only thing OC+ has over it is Zinc, the DM has more cal/mag though witch should be good for my next grow that might be in coco.

You know, I noticed the same thing with my plants. When I would do a mini-flush, they would always look better after.

What I'm wondering if that's because the flush washed some of the CRF nutes out, or put more into the medium.

I'm leaning towards the second explanation. In soilless media, it especially makes sense.

I did not do the type of watering cycles with my Sunset Kush plants that I would with soil. I don't think it's a good thing to let the combo of CRF and soilless media dry out too much before watering. Osmosis will not happen without adequate moisture. Think about the difference in water retention between soil and perlite.

That's why I'm really excited about running coco hempies.

Who makes that DM stuff?

A company called Florikan, but I read a rumor somewhere that they're selling the Dynamite branch of products to someone else who will continue them, probably under the same Dynamite label.

Cool thanks for that info.. i am doing a flush every 1 week

i am not sure witch one it is? but i am leaning towards the 1st one because in my temps the OC+ should be dumping more nutes out already.. so if things were building up and it was slowing down flowering maybe the flush leached some buildup nutes out.. in my temps i should already be getting allot of nutes dumping out, so the flushing thought sound more like what its doing to me.. but IDK really..lol. all i know is its doing something good.lol

I would tend to agree with you on this. I'm wondering if medium was not getting moist enough for long enough to release sufficient nutes. I added it to my little ones today and since they had been given plain water for the first 9 days they were a little on the light green side. I checked them tonight and wow. The newer growth at the top is dark green and the older sets of leaves are following suit. Amazing how much faster these guys react compared to soil.

You may not be getting much dumping because you top-dressed the CRF into the buckets, and the top 2-3" of the perlite stays a lot drier than farther down.

It may well be that your flushes are giving them what they need, not taking it away.

It's pretty damn hard to overwater a hempy. Why not try smaller flushes more often and see how it goes?

If your temps are high though, it would cause evaporation in the perlite to increase leaving the medium too dry to create an environment for osmosis like SS mentioned. Either way more water = better results so the heck with it.

This is a good idea Irish. This way you also have a better chance of determining what the issue could be. I can see where you mean he may be giving what they need rather than flushing through.
