Another question regarding rockwool

[Deforced]

Right guys, I'm going back to the old NFT system, basically I want to germinate in 1inch rockwool and then transfer to 4inch and keep them vegging in 4inch until a decent size so I can basically put straight into the system once the flowering room is complete. Now I've never done this before so how long can I possibly keep a plant in veg in the 4inch and is it actually possible to hand water rockwool until the system is ready? I'm trying to keep it simple as possible so any answers would be perfect for me. Thanks

I veg in 4x4 blocks and then drop em in my net pots for flower. Flood and drain DWC system.

it all depends if its auto's or photoperiods. i'm currently hand watering until my system is up as well. The roots might grow out of the rockwool, but when you transplant into the new slabs then it will work its manic

Just to clarify, I tried handwatering rockwool a while back and air pruning them, they were growing really strong but them

Very nice, thanks for sharing the photo. Them roots looks beautiful

 

[Deforced]

Ignore the top bit sorry

Ok thanks, they are photoperiods too sorry I forgot to mention. Just wondering what size I can get them before having to go on the tables because I will start them in the 4inch cubes and hand water before my flowering room finishes up. Thanks

Can I just ask when you start your seedlings in the 4x4 rockwool blocks, how long do they stay in the blocks for? Also what's your feeding schedule? Do you air prune them? Many thanks

 

[mojavegreen]

They stay in 4x4 anywhere from 1 to 4 months. Yes, air pruned.

 

[Deforced]

Ok thanks for that, appreciated

Neglected to mention my feeding schedule. I feed when blocks get dry, but not too dry.

No problem thanks for the help, I'm going start in 4x4 blocks and air prune until my nft trays are ready and see how I go from there. What size do you manage to get them in the blocks? Thanks

About 2’ to 3’.

You can keep them vegging in a 4" block almost indefinitely if you provide them enough water. After a few weeks-month you'll be watering numerous times per day though.

I understand, all I want to do is start them off in the 4inch cubes and keep them going for a few weeks and air prune them before my flowering room is finished, then literally just move them into the nft tanks. They seriously feel like they take forever when I put the seedling into the nft tray and grow from there.

 

[mojavegreen]

Just culled this plant. 5 weeks or so in 4x4.

That's nice pal, that stem is massive!!!
