And Dad always let us have one of those little 6 ounce bottles of beer then too. Schlitz was the name. I don't think it is around now either.

Yeah it's still around. I think It's made by Pabst ???

You guys are talking back home for me. I grew up just outside of Milwaukee. I remember when there were 200 breweries in Wisconsin, now who knows. Schlitz, Hamms, PBR, damn things have changed. When I heard Miller was moving it's head quarters out of Milwaukee I knew my world as I remember it is gone. I remember driving into Milwaukee on Blue Mound Drive going past the Miller sign, remember the ad with, damn who was that trumpet player, sitting on the sign, that was one huge sign, like 60' tall! That was before the interstate went in, yes, I've been around for a while.

RP, next time I see an algae problem here, I;'ll send them your way. I have had algae in my aquarium, and bought something at Walmart to get rid of it. I wonder if that stuff would help any, or kill the plants? It didn't hurt the fish!

Was just kind of forced to learn about all of it. Fighting my problem for a few weeks, I was getting frustrated, so I know how it goes. More then willing to help anyone who needs it.

Algaecides can work, and was the route I was going to go. You got to be careful, as they are designed to kill algae, a early form of plant. Some strains are more sensitive. Indica strains tend to be a little stronger and more tolerant (good news for most of us). They really can create some hassles, and not all work will all algae.

Physan 20 does work. Its nasty stuff. When not diluted, someone used it in a sponge to wipe down green house walls/windows. It burned his skin, so be careful. Stuff will kill most anything and help clean the roots. Clean the res as best you can. Mix a solution of 1teaspoon for 10 gallons of water. Run this mix for no more then 6 hours. Drain it out, clean up some of the gunk, and refill. When I did it, I refilled with a flushing solution made from Florkleen. Helped flush everything out. Ran that for roughly 12 hours. Drained it out and refilled with water and nutes. Physan 20 will kill fish, so not for use in aquariums.

One of the first things I did was use some Barley extract. Seemed to help slow things down, but this algae just kept growing.

Honestly, its something you will most likely deal with through the grow. Physan 20 and h202 help keep things in check. Wipe everything down and be sure to keep things clean also helps.

Physan 20 can be diluted into a spray as well, to help clean grow rooms, windows, etc.

I hate algae! :rollit:

I did my seeds using the wet paper towel method. you can find it here:
Deep Water Culture Tutorial, SH Kit & DIY
I put mine on top of my fridge near the back, the heat is pretty constant, and not too hot. Once the seeds pops and had a root, I put them into the rockwool cubes by splitting then cubes in half with a knife (thanks again for the suggestion Fry), and putting the root pointed down. My seeds popped in a little over a day, and was out of control in 2, so keep an eye on them. I planted mine when the root was about 3/4 inch long, that is too long from what I am told, but all of my plants are alive and doing great so far. My temps in my grow area don't go below 70, but i'm not sure about the water temp.
As for the SH tub, I have that too. I put the feeder tubes butted up to the bottom 1/3 of the cube and have a good trickle going with 2x 12 in stones feeding air into the system, so the water being delivered is highly oxiginated. Over soaking a seed will turn it to mush, same thing can happen to baby plants. I don't real experiece with full grown MJ plants in this sytem, but I have grown so many other plants from seed, I know a bit about drowning them. I've killed my share of seeds and baby plants because of bad lighting and heating, and overwatering. Good luck, hope this helps!

Thanks for all the info but I was asking for an additive of some kind (Superthrive???, idn) or something to prevent anything in the water from attacking the seeds. It's cold here and they take longer to germinate and grow a decent size tap root. :peace:

I know of a product, but can't post it here. The problem is, it's known to enduce hermaphrodite attibutes in plants. Not a good thing here obviously. Sorry i can't be more help, maybe an aquarium heater set to really low would help with the temps of the tub water??? :goodluck:

What are the temps? Seeds tend to have a better germination rate with high humidity and 70*+ temps.

Are you germinating the seeds, then putting them in the rockwool, then losing it? Or are the beans just not germinating period? Or how are you germinating?

That was for HGH

I know of no known chemical to increase germination rates. If there was, I would be worried about using it.

I have seen guys use the matchbox method. Generally reserved for older seeds. You want a match box, filled with some sand paper. Put seeds in and shake em. Basically grinds little grooves into the seed's shell to help with germination.

from another site:
Most seeds that fail to germinate do so because their shells, the testa, are too hard to break open and allow water to seep in. At the end of your germination period you may have found that some seeds have not managed to break open. You can help these seeds to grow by using a method known as scuffing.
Simply get a small box, like a matchbox and line the inside of the box with sandpaper. Place the seeds into the box, close and shake the box for a few minutes. Now that the seeds have been scuffed, their outer shells should break open more easily and they should germinate.

The seeds are not germinating, not because something in the water is attacking them, but most likely due to the cold.

Are they old seeds?

Need to know how you are germinating, and how the temps are. We can figure a way to germinate seeds with a good success rate. You might need to germinate and start growth in rockwool cubes, out of the DWC bucket. Get the roots going and manually water. You can setup some kind of tray, with a heating mat under it. It would bring temps up to proper area for germination. Once you have some roots and a growing plant, they usually can handle the colder DWC system. But there is such thing as too cold. And young plants and seedlings are always at their most vulnerable.

I seem to be having a problem germinating seeds lately. It's cold here and they take longer to germinate and sprout. I have lost 4 femmed seeds in my SH tub and I'd like to know what I can use as a starter solution to encourange germination/sprouting and prevent bad things happening as well. I have some SM-90, but I dont know if I can use it with seeds. Can I?

Hey homegrown

I had a similar problem. What I did for the beginning of this grow was to keep the res temp around 80 degrees from the time I dropped the seeds into the rockwool until I saw sprouts. I had 4 plants and all 4 sprouted within 2 days.
Then, I lowered the temp a few degrees a day until back to normal schedule.

In the cold months, the seeds seemed to relish the warmer water.

Peace

I think you guyz are right on with this one, I've always used some method of warming for germinating my seeds, since I keep my house very chilly!!

You and me both! I'm a warm blooded big fella, so I like the air COLD.

I remember a few years back, got too anxious and planted seeds in dirt around early April, maybe late March. The weather was colder then normal and barely anything sprouted up. Used black plastic mulch to help bring the heat up. Was quite the learning mistake. Now I wait, and test soil temps.

good advice
 
HGH,

Here's what I do. I soak my seeds in some 5.0 to 5.5 water. I mix up about a gallon, ph it and add one or two drops of superthrive. When the seeds have sunk to the bottom of the cup I place them in a wetted paper towel on a styro plate and stick it on my router. At the same time I use that same water to soak my rockwool. Within about 24 hours the seeds have cracked with a 1/4 - 1/2" tap root. I set the system up, insert the now conditioned rock wool cube and place the cracked seeds in the rock wool just barely deep enough to cover the seed. I then have a seeding in a day or two.

I don't know if the superthrive is a determining factor on my success rate with popped seeds but I've only lost a couple and I knew they were old when I started. Hope that helps.
 
Hey rose, thanks alot for the compliments, none of it would've been possible without all of u guys, but I do have some side lights going right now, the only problem is, there isn't any room to go on the sides of the plant, and with those 2700k cfl's in there 1 85W, and 1 42W it gets pretty warm. they were to close to my leaves one night, and I got some light bleaching on a few of the leaves. (from the hps being to close as well)so I moved everything a good 3-4 inches away
 
It's a 3x3 silver edition hydrohut, I've also got 1 85w cool white, and 1 42w warm white in addition to the others mentioned before going as well, I was thinking about just laying them on the ground if theres any room left. they're already growing well into the walls of the tent, one side is actually covering the intake to the tent, so the leaves in that area are getting wind burned! also the ones underneath the front of 1 of my plants is getting wind burn as well, but I've got to circulate the air so I guess a few dead leaves on the bottom every now in then is ok right? does anybody know how deep I can penetrate the canopy with a 430W Agrosun red bulb at 16 inches away? this rez change tomorrow should be fun
 
Damn ! I just had to pull another male last night ! That makes 8 out of 10 males in my batch of seeds ! Thats the old if I had any luck etc etc .! Oh well at least I have enough to smoke !! Next time I'll go with clones !! :peace:
