    150 watt hps Advice

    from my experience with 70w hps in a 16x8 inch pc case.. you will be able to grow well over an ounce, probably 3-4 when you get used to the box etc. And you will be able to keep the light much closer than 8 inches away.. my 70w hps is cold to the touch on the side the fan is blowing on it...

    That Lowryder was (sortof) on 18/6, but the box was NOT light proof, so it effectively had 18 hours light, 6 hours of twilight. I have done similar on all my plants pretty much, for stealth reasons (if the box is off all of the 'working' day, its a lot stealthier if your landlord fancies a...

    Thanks man. It's a shame the PC group doesn't have a proper forum, or else I think we'd all benefit from a bit of idea-sharing etc. I have rebuilt my boxes so many times now to fix stupid mistakes I should never have made that its verging on ridiculous :)

    Male/female ratios in autoflower plants

    Hi, I have been growing lowryder 2 for a while, and 1xgrow back I tried growing one in a pc case with a hps. (see sig for details) Anyhow, I noticed then, i got far FAR more males than I ever did under CFL (including a big warm white 125w envirolight) - possibly a factor of two more males than...

    Auto AK47 PC case grow

    I just germinated mine the same as I do in soil, in little peat pellets (the ones which expand when you put them in water) which i just placed on and surrounded by the clay balls, in the net pots. DWC was surprisingly easy with the PH and PPM meters, definately easier than first time soil...

    Lowryder #2 70W hps PC case grow

    Pot was 3 or 4 litres, but the bigger the pot, the bigger the plant in my experience (with enough light anyhow) I have no idea how much you'd get from growing on your windowsill. You'd probably get much more yield if you could put them outdoors somewhere Id have thought, but I dont really have...

    Lowryder #2 70W hps PC case grow

    Yeah, im not opposed to CFLs by any means, I just found them somewhat harder to cool effectively (more surface area to point a fan at). Good luck with your grow. Its always nice to see more of this sort of grow, I have so many unanswered questions :) Id quite like to see if more plants in...

    Lowryder #2 70W hps PC case grow

    I never LST'd lowryder before this (but i definately would again now) however I did LST some auto AK, which is what convinced me it'd work. Final dry weight, as put into curing jar just now was TWENTY THREE grams! I am quite surprised, I was expecting more like 14g from this plant. Two this...

    Auto AK47 PC case grow

    I used the blue one for the first two and a bit weeks, then switched to the red one afterwards. I'm not really sure how much of a difference it makes, when I sprouted some seeds under the red one they werent noticably any slower growing. I mostly bought both because I figured each bulb would...

    Lowryder #2 70W hps PC case grow

    There was an intake fan at the bottom, an exhaust fan in the normal pc fan position, and a hole where the power supply should have been (i was too lazy to fill it in) Got to about 86f maybe a little higher at about 1/2 inch to the side of the bulb. I couldnt measure the temperature behind the...

    Auto AK47 PC case grow

    Erm yeah, 2.2 watts per gram... not grams per watt. Apparently my brain thinks in reverse sometimes. Xander: The small one wasnt really trouble or anything, it just took so long to dry out initially that it never got a chance to get big. Who doesnt always want more though :) Thanks for all the...

    Lowryder #2 70W hps PC case grow

    Yeah, the ballast is in a little metal tub behind the box. Buzzes a bit, but its not any louder than the fans. Gets quite warm too, Putting it in the box would add quite a lot of warmth I would have thought. Also, heres a harvest pic :) Not fully dry yet, so I havent weighed her, but she looks...

    Lowryder #2 70W hps PC case grow

    Thanks! If i were to start again now, id add more plants, but in smaller pots. Im also considering moving the light back against the far wall of the box, which would maybe allow for an extra plant, one on each side and one to the front of the light. Also, id keep them a tad further away, as...

    Auto AK47 PC case grow

    33g Dried from the bigger plant. Plus 8 or 9 from the small one (not pictured due to being smoked already) Obviously the small one was a problem, but the DWC could easily have outgrown that case and light, so I think perhaps the extra effort (well, noise) of pumps and things is unnecessary, and...

    Lowryder #2 70W hps PC case grow

    Some new pics, In the first one you can see just how close the plants can get to a 70w HPS. There is some slight curling from heat on leaves which have been too close, and i trimmed some of the longer pointier leaves which were close to the bulb, so i could get more surface area closer to the...

    PC GROW CASE....help noob here.

    Note as well, Lowryders (and all autoflowers I have tried) are very nute-sensitive. I use hydro nutes at approx 2/3rds of the MINIMUM strength given, and water at least once in between nutes. I also dont give nutes at all before they show sex. Try to plant them in as large a pot as possible...

    Lowryder #2 70W hps PC case grow

    Oh, completely out of sequence picture here, but this is what happened when I let the top cola get a bit too close to the light.. (note, only some large leaves on the side of the cola were actually too close, and none were touching IIRC) All the large leaves curled up to make a leafy bowl of...

    Lowryder #2 70W hps PC case grow

    And a bit further along again.. Shes doing her best the poor little thing. Starting to look quite pretty :) Hopefully she will be finished in 2 weeks, as my lease is up then.. This 70W hps has done much better than i expected, If you could get it in a box the size of a bedside table you could...

    Lowryder #2 70W hps PC case grow

    70W hps is LOVELY for seedlings, you can get them easily within an inch or two of the light, and crowd them around it. They love it, growth is great. Course this might be what caused 4/5 males.. but Im hoping it was just an unlucky batch. Anyhow, heres an early(ish) pics from a day or two after...
