Hi

I have been growing in coco for years and have changed to DWC. When I put the seeds in the jiffy pellets they grow till roots pop out the bottom. Then I put them in rockwool but they don't seem to be growing in to the rockwool the roots just stop????? any help or advice would be good.

Am thinking about putting just the jiffy in the net pot and covering with clay pebbles.

Thanks

ps how long should it take for the roots to come throw the rock wool?
