in that space. I would top'em. I don't generally recommend this, but in your case I would top, and flower in 2 weeks. Peace
Don't worry about all the stuff you don't have. get a finished grow in...with what you do have.
FYI MH for Veg, HPS for flower Or;
cfl for veg and any HID for flower.
I ahve flowered with both MYH and HPS, and I actuall vegged and started flowering under MH which seemed to elongate the buds...after 4 weeks I switched to the hortilux, and I never had seen before the giant Kolas I was able to produce on those plants. anyway...rambling. Peace

First of all, thanks again to everyone for all the advice.
Now, moving on and asking for more advice
I got out the toolbox today and started ripping out what could be ripped out of the little cubicle my plants are trying to grow in. I was able to get some small cabinets and a tiny little safe out which gives me a total height of 4' on the right side of the cabinet. Can't do anything with the left side, but provided future grows are only 2 plants, they'll both fit on the right side and will have a little more headroom. That gives me measurements on the right side of 2'2" deep by 1'4" wide by 4' high. 2 plants, one in front of the other, fit nicely there now, and they have the increased headroom. And once they clear the ledge to their left, they still have the full width of the cabinet to spread out.
Beyond that, the only HPS option currently available for me was only 70 watts. I went ahead and got it and am wiring it so it will be ready tomorrow. Probably a complete waste of money being so weak, but it was going to be that or nothing. Hopefully I can add to it before my next grow and get a few more watts in there. And of course that fixture is going to take up a bit of my new headroom, which brings me to my first question for tonight. Obviously I can't go with just the HPS at 70 watts, so with the combination of the HPS and the CFLs, how should I position the lights? My first thought would be to position the HPS as close as is reasonable considering it's a big fixture and won't be easy to move up on a daily basis and then ring the CFLs around it. But if I do that, will I be taking away the only good they're getting by having the CFLs too far away? I also considered putting the CFLs to the upper sides of the plants to try to illuminate the interior a bit better, but with the weak HPS, would that just pull the plants towards (and eventually into) the CFLs, meaning they would do better to just stay directly above them? Currently my prevailing idea is to remove the reflectors from the CFLs and keep a CFL directly above each plant and just put the HPS at ceiling height (which is not a whole lot further away than it would need to be anyway considering all the plants don't have that new 4' headroom), but I'm a bit hesitant to remove the reflectors because I'm not convinced that wimpy little HPS can make up for the loss by not having the reflectors, but of course I could be completely wrong about that. Any suggestions?
Next on the list of new questions is about my soil for flowering. I started 12/12 last night. I picked up one of the cheapo soil test kits and probes today and get the following readings. Ph on the probe is giving me a bit above 7, using the chemical test, it's showing about midcolor between 6 and 7, so somewhere around 6.5. The Nitrogen shows "high", the Phosphorus shows "very low" and the Potassium shows "medium". In hopeful anticipation of flowering I picked up some Green Light brand water soluble Super Bloom. Never heard of it, but it's the only high phosphorus product they had. It's 12-55-6 with 0.1 of chelated iron. All the faqs I find all say to increase the phosphorus, but they never say exactly when to increase it. Any advice on what point I need to start adding it - before flowering (now), immediately upon flowering or at some time interval after flowering starts? Also, 55 seems very high from other things I've read, so do I need to do some extra dilution for the entire time or should I go ahead and go all the way up to the recommended mix ratios (I'm thinking something like 1/4 strength, 1/2 strength then full strength if I go all the way up).
Wow, sorry to be so long with all that. I really do appreciate any advice anyone has to offer.
Thanks.

couldn't address whole thing but phosphates when you 1st induce flower, to induce stronger flower sets. Potassium is the biggie after that in flower.
As far as 70 watt hps. cool. get another. lol No proper lighting is a waste...

too true, as latewood said. good light is good light.
you have been misinformed. i know that greg green's bible has that as a typo...
hps is good for all stages, but has been said to increase male count if used in veg. hps is great for flower.
mh is excellent for veg. good for flower, you get less stretch, and denser buds, but the yeild is considerably less than with hps.
a combination produces the greatest overall effect, iml. ie, i was using a 400w mh with a solarmax gold bulb (more red than standard mh) and a 1000w hps. no fluffy buds, all dense, and a very good yeild.
sorry for missing you...

I use in this order. cfl>MH>hps. But I have use a MH all the way to 4th week of flower, and got one of the biggest yields I ever saw.
I also believe that the light doesn't really decide the sex. I think it is light period, (no more then 16 hrs) and low stress maintenance. Vit B and hormones. "superthrive". i have started seedlings under each type of light I mentioned and have the same high % of fems. Read up on "henks" take on feminization techniques. (Dutch Passion Seeds) The potential of female is in each seed. It is all how you treat the seed. sometimes you lose, and get a male, but "henk" has proven that even with the best "feminized" seeds...you had to create an environment condusive to "creating" female plants. Hope this helps...Peace
