Why is it that plants grow much bigger outdoors and produce more yeild than indoors, in theory would it be possible with room space and height to be able to mimic the outdoor overal yeild to an indoor enviroment.

I ask as I cannot get my head round it, was thinking allsorts, perhaps it has everything to do with temperature, was reading an article on the web which differed greatly from what most books iv read state in relation to temps. It seems to be a knock on effect, everyone reading everyone elses book and mimicking it to a degree, this use to happen in other books iv read on completly different subjects.

It stated that plants should be kept at a temps of 33c instead of 27-28c for better yeild, im wondering should it be accurate that perhaps it has to do with the plant expanding in order to cool itself down. I base that on another book I read which stated plants do exactly that. Obviously the other factor of outdoor plants is you cannot mimic the weather, hence plants still survive in much higher temps than most books state and also produce great yeilds with no restrictions with height or space.

The must be elements in the equation which as yet I have not found or understood as to the main reason why this cannot be done, the question is, what exactly is different which are key factors which differ from both enviroments.

Obviously heat, light, air, other factors, all of which can be mimicked indoors so what is the key which unlocks this mystery.

Will find the article on the high temps needed should anyone want to read it, looked decent.

I'd like to see you find an indoor lamp with the energy of the sun!

Plus root mass is a big factor. Add in a touch of ventilation (there's nothing quite like the outdoors for that) and you've pretty much got your answer.

simply cos outdoor plants are vegged for much longer periods

if you start a plant off indoors and then plant out say end of april/early may it won't naturally start flowering til about end of august
that's like 16 weeks veg outdoor plus say 3/4 weeks indoors before hand

veg anything for 20 weeks indoors and i guarantee you'll get buds galore

sunlight doesn't have that halflife thing going on like lamps do, so buds are huge all the way down.
Nature always beats machines

not this year

This is interesting simply because im vegging for 3 weeks longer than I need to, simple reason is that im waiting for my other 10 plants seedlings to catch up which are 3 weeks behind in the same tent. So in effect the Dutch Passion Power Plants will have 3 weeks more under veg than usual under 600w MH, then during flower change the bulb to the HPS 600w, perhaps a 200w blue spectrum lower down the tent to increase lower leaves with bud sites also.

Lets hope thoose bud site increase, already meant to be high yeild plant as it is

In the long run...

I done that, with two plants.. sadly the bigger of the two failed to floweR ( was not a male though ) but the other one produced a nice sum, and it was a Sativa so im pretty impressed it finished on time, They where 12ft and 10ft tall ( Thats when I had nice trustworthy neighbours.. )

I was pretty amazed because I only seen indicas grown out doors, and even then there pinched alot by the grower who I knew. got about 9oz dry, which I was more than amazed with as this was my first grow.

And hopefully ill get a veg room ready for 2008 outdoor so I can try this again ( but I think ill be training the plants )
