Look up Mainfolding (Mainlining) I top 3 times giving me 8 mainstems. You can do more, next would be 16 mains then 32 mains so on and so forth.
Just wait till the two new mains reach 6 nodes then clip at the 4th node, you want time for the roots system to develope, the key to manifolds success, powerful rooting system. I would say your looking at about 6 to 8 weeks veg. depending on your experience and grow method.

1.) Create “Base”
- Let young plant grow 6 nodes
- Top to 3rd node and clean all extra growth except top 2 growth tips and their fan leaves
- Now you have 2 main colas – these form the “base” of your cannabis manifold
2.) Create 8 main colas
- Let each side grow 4 nodes
- Top to 3rd node on each side
- Instead of cleaning all other growth like in the last step, just remove all the growth from the 2nd node on each side, leaving growth from node 1 & 3 on each side
- Now you have 8 colas!
3.) Vegetative Stage
- In addition to regular plant care, specifically check plants at least twice a week to make sure everything is growing flat like a table. Older stems start getting hard and woody and are more difficult to train, so if you check plants at least twice a week you’ll be able to bend stems while they’re still young and flexible. Getting used to checking on your plants regularly is a great habit that will serve you well in your cannabis growing adventures!
- Try to fill every “space” under the grow light with colas that are a few inches away from each other, and all the same height. If at any point you can see a cola is growing taller than the others, gently bend it down and away from other colas.
- Use twisty tie to secure stems so everything stays in place, otherwise your stems will turn back up overnight!
- Keeping up with this process throughout the vegetative stage gives you a flat, even canopy with many evenly spaced bud sites.
4.) Flowering Stage
- Switch to the flowering stage when the plant has reached half the final desired height.
- Continue to arrange colas to fill up your space under the light for first 2-3 weeks after the flip to 12/12.
- If any colas are growing much taller than the others, make sure to bend them down and away during the first few weeks, securing them just like before. This is especially important for colas growing directly under the grow light since they are most likely to grow too close to the light and get burned!
- That’s pretty much it!
Although I use the 6/4 method, again I believe I get better growth this way.
This was my last manifold in 2015 I think, did not really trim as much bottom growth but still worked great.,
6 plants shared tent with 6 other plants kind of cramped, got over 3 zips per plant. You can see the size of the plants. Hard packed buds.

Thinking of doing this again on my next grow but do 8 plants in my 4x4 letting them get a bit bigger. I believe Indica's work best for this method. IMHO
