some (probably) stupid questions

-----whatever nutes homebase sells lol

Correct feeding is one of the main factors. Watch their NPK values, choose by that. More P and K for flowering. I'm sure you can find that info

I worked out that every square foot i have (3) gets just over 5000 lumens each. (I think this is enough to produce quality stuff, just not loads of it)

Yes this is more than enough. You can run both for the last month of flowering if you feel needed. MH effective on quality.

the plantrs seem to be different strains (one looks like its leaning more sativa the other more indica going by the leaves but the indica is taller!)

Try to keep them in same high for them to share equal light. Otherwise one can average on the other and dominate. But, your cabinet looks small for two plants. Maybe enough for small size plants. You may need to do some training.

i veged them for about a month, they got to about 6-8 inches tall with 6-7 nodes and then i switched to 12/12 my first question is........is this okay? the plants seem healthy and i know you can force flowering any time, even from seed, but i am aiming for about 2 oz per plant and the second question is.........given my situation, is this a realistic target for a new grower? if not can you sugest what i should be aiming for ( i dont wanna get my hopes up lol)

I didn't get what you asking but yes its ok 12/12 anytime. They'll keep growing in 12/12 too. They get bigger 2-3 times more than now.
That's possible to get 2 oz per plants depends on conditions.

as we all know HIDs get hot, real hot and i was wondering if putting a thin perspecs sheet between the light and the top of the canopy would alow me to get the plants closer to the light to try and get around the inverse law or would the plastic eat too much light, making the heat gard pointless?

I don't know much about HIDs but I don't think there can be a real heat issue with 150W.
That sheet can reflect back some light. Better use glass. But only that can't be helpful on heat if there is no cooling fan for the bulb. Also distance of glass from the bulb is another factor on cooling.


And yes, +1 GaGrown. Picture.
