how to properly use rockwool cubes
Hi I have just started germinating my seeds and once the root shows I am going to put them in to rockwool cubes once there there what do I do as in
How to soak the the cubes
Where or how to put them in a propagator correctly and how to keep it humidity up its heated
How long to keep the seedlings in there before putting them in new pots and under mh 400w bulb
And a clear understanding of the temperature of too high with light on and off like max and min please help first timer
My strains are white widow and blue lemon thai dunno if this will help any info on water and ph would be great on seedlings
You don't want to soak the cubes. You want to keep them moist. All you do is pour a LITTLE water over them. You can leave them in the rockwool for the entire grow. You can put them under a HID light as soon as the first two sprout leaves show. 70-80F is a good temperature range.
Say my grow room gets to say 86 will that still be ok and do I keep the seedling in the propagator under my mh light for a few days and gradually take the dome off and when do I put the plant in to pots
Put the Rock Wool in the trash and put the seeds in some soil.. IF you want to go HYdro, simply wash the roots off after the plants has rooted in soil and off you go.
Will a 9w cfl be ok and thanks alot to all that has posted
9 watts is pretty puny. I'd want a minimum of 1 23 watt per 2 seedlings.

best use rookwool or water for cuts, if going hydro, as the less you mess with the roots the better, the plant will be vs washing soil out

Balance the ph level of the rockwool is a must. Several types of Rockwool Conditioner out there if you choose to go that route. Very easy to drown seedlings in rockwool also. Peat Plugs work the best, imho.
All I run is rockwool product and its great!

Propergator? Do you mean ez-cloner style or bubble cloner? With an ez-cloner I have eliminated the 2 inch rooting cubes. Once you have roots in the cloner, remove from the neoprean inserts and plant right into 4 inch cubes. I consider this the start of my veg.
Using 4 inch cubes will allow you full term if thats your game, but a drip system is in order if you plan on this. Will they be going onto a rockwool slab or another medium?
Keeping your temps in line 72-78 will go a long way in helping new seedlings so a smaller light for the babies is recommended, a simple 23 watt cfl will be enough to get you through the rooting process.
Flower room temps ideally should be 72-78ish with R/H of 40% or lower. Co2 will allow an increase in temps like to 90.
Veg room temps ideally should be 68-82ish with R/H of 40-60%
They will take a wider range for sure but if you can keep within these boundries you ward off a bunch of issues.
