Popcorn Buds and LST ...... what to with??

Wondering if LST at day 20 of 12/12 isn't going to shock my plants. Really hoping that a little LST will help rid myself of airy popcorn. Currently under 600w HPs running 6" cool tube. Grow tent should be here any day now... 4x4x60.

Have 6 plants under light, feeding them with local hydroponic store bud blend with good results. Was also wondering about the addition of mollasses, and when to start the mollasses. Hoping to spread 6 plants over 4x4 space with some LST for max yield. Also wondering about cooling issues with 600w in the 4x4. I know some people run 1000w in 4x4, but My fan only runs at 140cfm. Will this be enough?? Especially worried about scent in the coming weeks and plan on buying Carbon filter. Hoping that fan can handle that...... Any tips please feel free to post here...

A140 cfm fan is not gonna handle a 1000w get a bigger fan Max fan makes a 6 inch with built in speed control that can handle the heat

you should do 2 different vent systems. One specifically for the light pulling air from outside, through the hood, and back outside. Using a fan like this http://htgsupply.com/Product-6in-Inline-Duct-Fan.asp.

Then have your 140 cfm fan attached to your carbon filter inside your tent pulling air from the top corner. You need to have passive intake for this, ideally at the bottom of the opposite side. This means a vent or something that will allow air to come in as the pressure is created by your air outtake.

I have found this puts less stress on each fan and seems to run a little more quietly.

Cheers

yes you can lst 2 weeks into flower but you should have done it earlier. you may find it hard to train the branches at this point.
