I know this started out saying there was a limited budget.. but; I highly recommend a Clone Bucket (or similar). Mine has 18 sites and cost me $80.. Cuts generally take me 2 weeks at the very longest before rooted (tired old strain that's been cloned for years..) and as little as a week. I can tell you, clones using this method look one hell of a lot better than those living in rock wool, though the result is naked rooted clones. Good if you're going to a net pot or soilless mix, bad if you like using rock wool..

I also stick with Clonex gel and have 100% success.

My $0.02
