planting seeds question

i got cubes and the trays and clear humidity domes. my plan is to wet the cubes and push the seeds approx 1/2" down into the cubes and wet the dome and fill it with the general 1/4" water and wait for them to root and sprout, then transfer them to the 3 gallon pots. the water will be 5.5 to 6.0 ph.

am i on the right track?

i read somewhere to actually once they sprout remove the dome and let them continue to grow in the tray. if so how big do i let them get. you'll lose some roots if you let em go too long where the roots are down through the tray into the pan tangled obviously.

never did seeds, but adding a few more strains and also got behind on babies so it's also giving me more babies. how long does it take usually once they've sprouted and are roughly the size of a half dollar in diamter leaf end to leaf end across before they are say the size of a clone cause I had got some cheaper seeds that I started and it's like the plants sprouted and just stalled. just staying same size about that size and not growing. i got all good feminized seeds now and don't want to make any mistakes with these cause these costed some dollars.

thanks for any help or input.

I would germinate them in paper towel b4 putting them into the cubes but thats just my $.02

i would then have to slice the cubes down the side open first to insert the baby/root into the cube right? then into pot? or into dome? thanks

Hey I just tried some rockwool cubes to start some seeds. The directions on the package called to use a lemon to adjust
the PH and soak just breifly. After that place them in a warm humid enviroment. Within 48 hrs I had sprouts up on 15 of 16 seeds.
I had one dud seed.
I am impressed with it as a seed starter.
Anyway what you describe as a start will work and yes when they sprout raise the dome and begin to aclimate the young sprouts.
good luck with your grow

I also just started my seeds right in the rockwool. Except I used vinager to lower ph. Within a couple of days they have sprouted and 2 are already stickin up one inch tall. I wouldnt cut the rockwool in half to insert the seed. Just drop it in and the roots will grow down. If they already have a taproot when you insert them into the rockwool just stick the seed in with the taproot facing down.

ok great. i will just use my general hydroponics ph down powder to adjust my ph accordingly. thanks. i don't have rockwool plugs, i have root riot and another kind made by general hydroponics that are made from organic tree bark. they say they are for clones and seeds however.
