    4" Inline Fan = Airplane!!!!

    Hang from bungie cords so there is no metal-->metal connection (decreases vibration). Buy one of these: http://www.htgsupply.com/Product-Blower---Fan-Speed-Control.asp Once your all setup you can play w/ the speeds to find the lowest speed while maintaining your temps. This cutts down on noise...

    Noob, same bulb veg and flower. 400w Ceramic Metal Halide. day 25

    Looks good. I would stick with 400W CMH the entire way through honestly. My only suggestion would be to add a little more nitrogen to your next 2 feeds. I can see the lower leaves are yellowing quite a bit. I would only accept yellowing during the last 2-3 wees of flower imo. The best grows I...

    FIRST GROW 600 watts of tri spectrum led lighting. 2 weeks flower

    Looks good but look at all that wasted light. I wouldn't have cut so much away. The only parts of the plant you want to cutt are the bottom 1/3 of the plant (and only those leaves/shoots which arent receiving light. I think you cutt it wayy short.

    Apartment inspections

    My buddy grew in an apartment and had a similar issue come up. What he did was rent a uhaul and park it outfront at 3AM the night before. He loaded up the uhaul with all his plants (he had tons) and parked it down the street for the day. Since you are using hydro.. it's going to be much more...

    How to Adjust Soil pH (after you've already planted!)

    Hi All, After a lot of research on this forum and elsewhere, I have compiled a simple procedure to adjust your soil pH if you did not correctly do so before planting. I found a lot of useful information on here, but never a quick guide that had a case study from beginning to end, so I thought...

    Cooled hood or Cool tube?

    Go with the Air-cooled reflector. I have used both and found the reflectors spread the most light, evenly. The cool tube you pasted doesnt really give you any space advantages as I would only recommend one when you have VERY limited space.. something like this...

    When to start " Fimming"

    I fimmed my plants when they had about 4 or 5 true nodes and 4-6 inches tall. By "true" I mean not including the cotyledons or the first set that show when the seed pops. I did that and now, 5 weeks later, I have 8 plants 24'' tall with 6-10 colas per plant. I had never fimm'ed before and am a...

    Light Schedule Interruption

    How long should I wait to flower after cloning/lollipopping?

    Light Schedule Interruption

    Thank you for the advice. I actually topped and fimm'ed about 1 month ago. In only a month they went from 5'' to 24'' with about 4-8 colas per plant. This is by far my best grow thus far. So I already topped.. but I want to lollipop and clone, so what your saying is keep it at 24/0 until flower...

    Light Schedule Interruption

    Oh, and I caught this problem last night around 4AM. My cycle is on at 6AM off at 12AM. So, I switched it and they had about 2 hours of darkness last night until 6AM when they were switched on again and have been on since. Should I just shut the light off tonight at normal time (12AM) and then...

    Light Schedule Interruption

    Ah, I see. Well this was last night, and I wanted to do some cloning and lollipopping before flipping them to 12/12 so I thought I would switch it back to 18/6 again for a couple of days. I guess I can flip tonight and lollipop and clone from them during week 1 or 2 flower, correct? This would...

    Light Schedule Interruption

    Hi All, So I made a super noob move and left my timers on 24/0 for about 1 week. They had been on 18/6 for about 1 month of veg until this happened. The problem is, I was planning on switching them to 12/12 soon. I was wondering if anyone knew if this super stresses them out? I hope because I...

    Odor Control

    No problem, happy to help. One question though, where do you have your filter?

    Odor Control

    The problem is you do not have negative pressure inside the tent as you think. The 6'' fan has double the CFM of the 4'' fan. If I get you right and your 4'' (exhaust) fan is turned up only slightly more than your 6'' intake fan.. then I think that's your problem right there. The 4'' isn't...

    1 Month old plants- any advice?

    You are very far behind where you should be. That soil looks terrible, tons of bark and zero perlite. You should have added some into the mix. What's your runoff pH at? I bet its low and there is nutrient lock out. Try to adjust pH with domitic lime if its low.. if pH is fine then your soil...

    Will this stuff kill fungus gnats?

    goGnats never worked for me and I tried it for a solid 2 months once. Watered with it + soaked entire root systems in it and it didn't even touch it. Starting to get a couple gnats flying around now and ordered some gnatrol + a couple no pest strips + some gnat sticky paper. I have a feeling it...

    does my plant look healthy

    Doesn't look terribly good to me. Pretty stretchy, going to have a lot of trouble in flowering as you will need to add mucho support. What size pot is that? I would transplant it into a bigger pot with better soil pronto.

    I am only at week 3 veg (not including 1 week seed sprouting in solo cups). The burning is still going on but My plants look great and are already between 12-18 inches tall and very healthy bushes (I fimmed them all). I started them in solo cups for 1 week, then 2 weeks in 1 gl grow bags, then...

    First Indoor Grow, Need Suggestions

    I used straight FFoF soil and I am glad to see you have the same type of leaf burning I have. It's definitely a strong soil and next time I am going to cut it with coco coir and or perlite a bit more. Maybe 80/20. It also has a bit low of a pH so I will add some dolomite lime next time around as...

    Question about fumes from waterproofing sealant

    In case anyone cares I removed my beautifully made tables and are rebuilding them this weekend with only silicone caulking, no chemical waterproofing. After an exhaustive search on the internet I found several threads about "bad grow room syndrome" where the chemicals in raw materials negatively...
