Using rock wool to germinate my seeds


#1

Hey guys, I am going to take six seeds of unknow variety plant them in some rock wool cubes I think the cubes are 1 1/2 or two inch cubes. I am thinking of soaking the cubes in ph 6.0 water with a grow solution. This soolution should be the same as the solution that will be in my buckets so as to help them transition better. The system will be a 4 RDWC grow bucket system with a storage tub reservoir and will use the water fall effect with air stones.

I have two 35 watt led grow lights I don’t know there spectrum. Will this be enough power for the 4 plants or should I used the 1000 watt cfl light set?

P.S. How do you post pictures?

First I would
Like to welcome you to ILGM. Also you gota visit the lounge. That’s where we all get to know each other a little better. And don’t ask for a drink cause I’ve been waiting 6 mo for mine lol
Any way I’ll bring in my buddy he knoews a bit more on that than I
I’m a soil guy.
To send pic-s look to the bottom right see where it says Upload. Right there you can load pic’s

@Rev_Nasty, welcome to ilgm, and you’r light should be good but maybe eventually look into switching to the 1000 watt setup, as plants get bigger they are able to harness more light ( in a plants world light=energy ie; chlorophyll and chlorplast, photoreceptors, its all important), as for hydro ph, (rdwc) your perfect ph should be 5.5-5.6. 6.0 is a little far out of range.

Hope this helps out, good luck my friend

OK. Here we go. It is a 1.5" cube. You do not want to use any solution. Plain PH’d water is all you nee for germination. If you add Nitrogen to these seeds, they will burn up.

Hope they all pop.

Pictures can be uploaded by selecting the arrow that point “up” above this window. I suggest you edit you images to 50% in order to allow them to upload efficiently.

Happy growing! :slight_smile:

Could it be my browser as I have looked bottom right top right looked into a reply and I still do not see an arrow that will say upload images or upload anything.

So i will adjust my ph down add no nutrients.Soak the cubs in warm water? Put the seed dome in a warm dark room the temp will be 76 degrees (is that too cool) Should i water later on with the same water type for instance when i make my ph water to soak the rock wool should i just make enough to water later in the cycle?

Do you have a button that says upload in the bottom left


#8

I found it it is on the top line of any box that I use to reply or post the seventh button from the left, if anyone else is having this issue. Thanks for the help guys.

As for this has adjust it down to 5.6, and 76 degrees is perfect, and you should use clean fresh water, get them clean water it has fresh oxygen in it and there for will be better for your roots, and no, no nutrients until your plants have a well established root system (or old enough usually when your embryonic leaves die and your plant has 7-10 leaf nodes)

Once I place my seeds in starter cubes; I only mist the top of the cube lightly a couple times a day. No need to add more water unless entire cube starts to dry up. Rockwool retains water for a long time. This varies if you have a fan blowing on them but, I doubt you are at that point yet. Make sure to have a small fan to gently allow a breeze to move the stem once popped. This will strengthen the stem and keep seedling from falling over in case your light is too high.
