Vegging in Rockwool before transplanting into dwc

Hello i have 3 plants under a 600w hps in a 1mx1m room due to be ready on christmas day, they are in dwc buckets.

I have 3 seeds germinating, i want to veg these until xmas day until they can be moved into the flower room.

I plan on using a small cupboard with upto 100watt of fluoresent lighting to veg in, but i wont be able to veg in dwc because i cant fit the buckets in the cupboard and i dont have extra pumps

So im trying to think of a way to veg for 2/3 weeks

Would i be able to use big rockwool cubes and hand water?

or any other suggestions?

Thanks

What you're talking about is DTW - drain to waste.. and yes it will work, also since you're doing this in the seedling stage, you won't waste barely any nutes.

so how exactly does drain to waste work

Sure I keep some clones vegging in starter plus fire over a month now just to retain the genetics. Its kind of hilarious because they look like palm trees. Just give them a dip when they dry out.

You'll want to transfer to bigger cubes if you plasm O'flowering them. At least two inch

DTW - watering rockwool and letting it drain out.. don't let the rockwool sit in water or nutes.. it has to drain, hence drain to waste.

The only time I do it is right after germination for a few days while they're not yet in DWC.

Have you thought about using a smaller container for the DWC until you can move them to their permanent buckets? There are several threads about growing DWC in those plastic Folgers coffee cans. I personally use a smaller, flatter, shoebox sized DWC starter to keep them in for about a month. Then, when they are ready for flower, I move them to the normal buckets and put them in the flowering tent.

Thanks for the input
