Critical Mass Tree Grow x 2

Everyone has a different number, also depends on you set up. Most people say the magic number for a perfect set up in a g per watt, but ive seen people get 1.5

Hi bestgrow,

Thats not a bad layout, one of the best is to use multiples of this. O = Bulb X = Plant

O X O

X O X

O X O


bgmike8 its horses for courses, shades have to be used for Flat SOG grows as vertical bulbs have to be hung between the plants for them to be efficient.

It really comes down to what your preferred style of growing is, 1.5 + gpw can be achieved from a tree grow of just two plants using vertical bulbs. It is also quite easy to get the same number from a flat SOG but obviously you have to use a greater number of plants.

Another factor is if you combine sog into a vertical grow and use vertical bulbs you can achieve 2+ gpw, so as you can see there are many factors involved not just whether or not to use a shade.

Hey Heath,

This all looks crazy!!!

i was thinking about Scrog but might just do a couple of trees. So you had 3x600 watts for the critical mass. Where were the lights each positioned height wise??? Was the bottom buds as nice as the top or are there still popcorn nugs with this method>>???

I know this has been asked before but forgot.... Do you top/fim or supercrop or anything at all or just let it grow?

Thanks for all this advice and info!!!

Thaank you heath for this amazing post! I have been kicking the idea back and forth for months now, about switching to vertical, but this thread has more than made up my mind. You are truly a master at your craft and we all appreciate your helpful information. I have just two quick questions for you, does the vertical bulb setup cut back on sooo much of the radiant heat usually generated that it may not be necessary to use a cooling system in smaller areas? Ie fans may do most of the work, without having to get cooltubes or ac systems? and also how well would a soil grow do compared to hydro? Is it still somewhat comparable yeild wise? I know that a kickass hydro setup can really maximize yeild but will a soil grow still do very good in this type of setup?Also in a 4w x 2.5L x 7H size room how many plants how many 600w bulbs? thank you sir

Hi scrog69

Yes the vertical bulb eliminates a lot of the radiated heat problems you can get with shades. I work on exchanging the air in my rooms at least twice a minute and dont really suffer heat problems.

Soil will work very well for this style of growing, although I don't think you would achieve these sort of yields Im sure it would be as good as any other way of growing in soil.

Your room size makes it a little difficult to fit much in there you could have some small plants around a bulb or have two larger plants with one or two bulbs, one directly above the other (with a bulb distance between the two, if that makes sense).

I know you want to give this style of growing a go but it would probably make more sense for you to use your space with one or two shades as it would make the most of the room you have available?

best of luck

thanks for the advice heath its greatly appreciated, just from your opinion if i was to set this style vertical grow in a larger space say 8x8x8 would u recommend vertical over horizontal anyday? i mean are these tree grows the way to go for power yeild with multiple 600w's? does it out yeild scrog or sog by alot, also for a semi novice grower is it easy to manag?, since the heat levels should be far less? Sorry for all the questions i know your a popular man on here! i didnt quite understand your suggestion in my smaller grow area, did u say that i shud prolly stick with horizontal refelectors or just hang some shades to help the vertical grow? thank you for your time
