Monster Cropping

I did not want to do another diary on a strain I already grew but the last Mango Tango plants I grew I kinda screwed up royally. I hope I have enough time for one last grow in that tent before it gets too hot for growing around here. I tried to start another strain but the seeds refused to germinate so I thought about starting a plant from cuttings. After some researching I learned about monster cropping which is taking cuttings from a flowering plant. For monster cropping they say its best to take cutting from a plant around 3 weeks into flowering. i didnt have that option since the donor plant is about 11 or 12 weeks into flowering. The cuttings did come from the bottom of the plant where I seen some small buds starting so I cut those buds, used clonex rooting gel on them an put them into some rockwool that was soaked in recharge and placed them into a propagation dome. The plan at the moment is to let them go for around 10 days under the dome. By then I hope to see roots coming out of the rockwool and will transplant them into solo cups for about a week and then into 7 gal grow bags with Fox Farms Ocean Forrest soil. Then when they are about 3 weeks old will flip them into flowering. From what I read they say monster cropping will produce shorter bushier plants. All comments and advice are as always welcomed. I been growing since Sept of last year so my experience is not much and any help is appreciated. Note: The donor plant is a Mango Tango plant from Elemental Seeds that I bought from Cannabis-Seeds-USA in california. https://cannabis-seeds-usa.com/products/cannabis-seeds-usa-mango-tango-seeds

Slow starting. Not sure they are going to do anything. Been over a week and no roots out of the rockwool yet.

Finally seen roots coming out of the rockwool. Planted them into solo cups with fox farms ocean forest soil.

found them dead last night.
