I must also not that I just came up with the screen idea and that screen was slipped over the plant very carfuly at over almost 3weeks into flowering . So this plant didn't grow into this screen but was manipulated into it . I could just see the benefits even this far in and decided to chance it on , I didn't cause any damage and it has continued growing so luckily i didn't stress it .
So to make it clear the obivious benefit I saw was spreading her out wider and opening up the middle easier .I think i will still need additional support as they grow tall , so here soon I will put in some bamboo stakes , .
Ideally for my situation in the future I will install the screen as soon as I transplant to the 5g buckets and plug in 4-5 bamboo stakes , i do this 2 weeks b4 flowering. This way it has time to veg into the screen and you can get her trimmed up underneath the screen b4 flowering . Placing the stakes at this point doesnt disturb any of the roots. Then at the end of that 2 weeks she is ready for the flip with everthing already done that could delay flowering , excess trimming, screen and stake instalation.
So this is a learning process in the making to sum it up.
