Hey all ,
After a little research I've decided to try air pruning roots of seedlings to hopefully encourage faster root growth..
If your interested look up DR. Whitcomb air pruning roots .
Lots of neat info here.
But basically he says a tap root is a evolutionary defense for plants so they can survive harsh environments by sending its tap root down deep
In search of water.
... but he says that the tap root is unnecessary in the grow room because we provide all the plant needs and is a waste of plant energy.
He says a large fiberous root system is best
I encourage to watch the video for impressive test results and im not quoting him just giving you the jist of it.
Other studies show roots can actually sense gravity and naturally go down even around obstacles (duh)
Anyways being one that always heard you need to keep that tap root happy
I never would have thought to intentionally reduce the length of the almighty tap root.
So i took 6 seeds (freebies)
Dutch passion auto blackberry kush 1
Seedism exodus 2
Seedism lemon gold drops 1
Thseeds bubblegum 1
And blimburn green crack 1
I put them in 4inch rockwool cubes that are elevated on a rack .
They popped right around Christmas
And i observed in a day or 2 the tap root went almost straight as an arrow to the bottom of the block then a few days later another ect.
Now a little over 2 weeks the blocks are filing nicley and i intend to keep them in the blocks till its mostly roots
Then i will transplant into the final systems..
Hopefully they will explode with roots since they will be allowed to grow as big as they like.
Which after seeing DR. Whitcombs results im quite hopefull
So i know other people have done this but has anyone here done it?
If so was it worth it?
I know after finding out about it from a youtube guy. Grow pot cheap .
His video is called the first 4 inches is all you need.
Hence the name of my title is a shout out to him
He grew some nice trees that where supposedly autos.
Ill post pics later as im busy today
Just seeing if anyone eles has done this
