    Best Way To Light a 10x10 Grow room

    Using a general guideline of 50 watts per square foot, you'd want to use five 1000w lights for complete room coverage. However, I think you could use four 1000w lights and achieve excellent results. I would recommend HPS systems over MH because of the higher lumen production they provide. And...

    400w MH

    You should have excellent results with a 400w lighting system as long as you're able to confine your grow area. Ideally, you don't want to have an area bigger than 4'x4' for a light of that strength. And I would definitely line the walls with Mylar to improve the lighting efficiency. Why are...

    My cabinet grow journal!

    I've never seen it at Home Depot or Lowes, but that doesn't mean they don't carry it. A search of the Home Depot website didn't return any results either. However, they could be selling it under a different name. I guess you could always go to your local Depot and spend some time scouring the...

    single cola plants?

    Hygrozyme, used consistently at every watering, will help produce the thick stems you are looking for. It is available online and at most local hydroponics stores. You should also have a fan blowing air at your plants 24x7. The air current will create micro-fractures in the stems and branches...

    Mylar is a polyester film with a metalized reflective coating. It was developed in the 1950s by DuPont, under contract by NASA, for use in the space program. Among other industrial uses, Mylar is most commonly used as a material for making balloons as well as lightweight emergency blankets...

    400Watt HPS..1st attemp..unknown/known seeds

    I start manipulating stems and branches from the time they are about two weeks old. I focus on guiding the side branches through the fan leaves so that they have access to direct light. If I didn't do this, all my nice side shoots would live sadly beneath the fan leaves, never leaving the...

    Toxic Salt Any Ideas Why?

    Your humidity is fine. You never want to be at 60% RH. The optimum humidity range for the vegetative phase is 40%-60%, but you never want to be at 60%. 45%-50% is the "sweet spot" for the vegetative phase. When you move into the flowering/bloom phase, you want to drop the humidity down below...

    Toxic Salt Any Ideas Why?

    I'm still not seeing any evidence of a salt buildup. But I realize that a picture only shows so much. Most varieties will begin experiencing heat stress at 85°F, but this number is not set in stone and will vary from strain to strain. It could even vary among different plants of the same...

    Pissed on my Plant

    I've never been a fan of starting off with a 12/12 light cycle; The yields are just too small. You'd be better off running a 24/0 cycle for for as little as 3 weeks before starting your 12/12 phase. By allowing for a short, intense vegetative phase, your final yield could potentially be double...

    23w CFL + Miracle-Gro Moisture Control + 100% sativa + 12/12 from clone

    Good luck with the new crop Faux! I hope all goes well and you harvest some spectacular juicy buds :-D One suggestion if I may... get rid of the aluminum foil. It tends to create hot-spots leading to heat stress and burning. Also, moisture can actually leach the aluminum possibly...

    Pissed on my Plant

    I'm a little confused as to what you are asking. If by "mature" you mean fully developed and ready for harvest, the answer is no. When a plant has reached its peak potency and is suitable for harvest, approximately 75% of the white hairs will have turned to a reddish brown color. However, if...

    Goin' to Amsterdam - Best places for seeds? Varieties? Limited Vertical Space tips?

    Oh, I know the Quentin well. Nice little place right off the Leideplein. How about that staircase though?? Not fun when they stick you on the top floor :-D Have you hit the Rokerij yet? That is, hands down, my favorite coffee shop. I just love the chill indie vibe and the comfortable...

    Pissed on my Plant

    I really don't believe that indoor growing will ever be relegated to the past. Outdoor growing comes with its own set of problems and issues, and legalizing marijuana just doesn't negate them. For one thing, the changing seasons will always be a limiting factor. People enjoy growing all year...

    400w MH

    If I were in your situation with regards to the space you are working with, I would definitely choose to grow fewer plants using the LST method. I think you'll be happier with the results growing a few large plants, than if you tried growing many smaller plants. You'll have less to deal with...

    Foxfarm nutes?

    You've still got the measurements confused. The BigBloom should be measured at 2 tablespoons per one gallon of water. And the TigerBloom should be measured at 2 teaspoons per one gallon of water. Keep in mind that the BigBloom is not a suitable stand-alone nutrient like GrowBig and TigerBloom...

    Toxic Salt Any Ideas Why?

    Hey man... from the newer pics you posted, I see what you were explaining. That the veins are not actually dark with a lighter shade of green on the leaves. From this new pic, I take back my earlier diagnosis of a magnesium deficiency and am now leaning towards some heat stress as your only...

    will bloom booster help my plant?

    Head shops don't typically carry anything related to growing. Remember, they operate under the guise of selling products intended for "tobacco" and "legal herbs", and not marijuana. Of course we all know what the real deal is, but the charade must be maintained in order to stay on the right...

    Goin' to Amsterdam - Best places for seeds? Varieties? Limited Vertical Space tips?

    And for great hash, you should check out the Blue Dolphin. It's just north of the Leidseplein on one of those small cross streets opposite the one that the Rokerij is locaed on. And while your near the Leidseplein, spend some time chillin at the Rokerij... it's my favorite chill place to...

    1st timer looking for input

    I use the FF line, including BigBloom, and have been very happy with it. Keep in mind that BigBloom on it's own is not a suitable fertilizer. It must be used in conjunction with GrowBig for the veg phase, and TigerBloom for the flowering phase. It does contain a very light dose of NPK, but it...
