    I was hoping for a link with new info.

    1000w in a 4x4 is 62 watts per sq. ft.

    That is in the intensity range in books about this. 45-50w is considered minimum for our plant for good results.

    I run 600’s over a 3.5’x3.5’ range and have no need for co2 added.

    And of course this is all with single ended hps.

    More usable light from a more efficient source would lower the wattage needed.

    Been awhile. Let me see if i can find it

    50 watts is the minimum requirement for cannabis. But if you have a par/micromole meter the results speak for themselves. Remember regardless of the wattage every bulb is different and the bulb/ballast degrade over time. I just replaced a 1000mh because the par/micromole value was diminished.

    Please don’t think I have an agenda. Profit margin on most items is 25%-50%. I own a brick and mortar shop. When you purchase online the price is so much cheaper. If you want to deal then ask me for a deal. Please don’t think that I’m trying to sell you snake oil.

    Sore it’s family time. I will reply tomorrow. Yes CO2 is worth it but are you a master grower?

    If a new guy walks in the store and asks for a basic nutrient package to use indoor with Coco under a 600w light, what would you tell them?

    not a master grower by far, just well versed

    a 4x4 should use 600W equivalent

    Entirely depends on the reflector and height needed.

    My light meter drops off at 3.5’ out on 3 sides of my reflectors. And plants farther out will lean in and adjust leaves for light.

    I use sun system blockbusters. They are a deep reflector designed for a direct down blast in a 4x4 area with 1000 watt se hps.

    600w doesn’t quite get there. But leaves and buds outside the prime area still do ok. I rotate and move the plants to get even light as I water them and level them with stands.

    Um, you have that backwards. I used it in many ways and found quite quickly that it's not worth the return to use it in veg!

    If you sell ornamental only products to marijuana cultivators...and I find out about it,
    I'll shut you down.
    Some manufacturers use tamper proof hydro product bottle caps
    while others do not. Can you do anything to urge those others to begin the practice ?

    I was jimmied once with watered down product fooking ppm's during a cycle.
    When my suspicions were confirmed I received inside info concerning the switcheroo, an inside job.
    We tested right off the shelf in store and an entire rack was tainted ! Nope, no way, no how will I ever risk
    another plant with an unprotected bottle. I stopped patronizing locals for these reasons. never looked back, save a ton of cash
    grow a better cleaner product and have more fun now.

    I know you dont practice any of this nonsense, but I bet you know about it.
    Please help by being part of the solutions.:weed:

    Hmm, I build my soils from scratch. Have for years. Use differently charge soils for different strains......I'm sure you understand that idea.

    As far as boosters and what you claim. I still say you don't NEED to use them to achieve what you think your getting out of them....Balancing your nutrition at the proper stage of growth, is the key to that.
    As far as commercial ops and "uniformity" in AACT brewing..YES THEY CAN!...I take it your not familiar with Vortex brewers.....They have 950 gallon brewers. That's uniformity, and bigger then any commercial cannabis op would need.....Simply following carefully the properly figured amounts of the ingr. to make the tea (We go by weight on our organic farms - yup, I do that too). You gain uniformity, batch to batch.

    Mammoth P is insanely priced! I mean $100 bucks for 500 ml...... Now that's a rip off! The whole cannabis nutrient/supplement market is being corrupted by greed. Marketing is specifically geared to new and seriously uneducated growers!!!! You can find the same things sold for growing use (hardware) for 1/4 or less the price of the same exact thing in a grow store....Then you have the fucking hype surrounding nutrient/supplement makers overblown claims. Your comments on your use mirror the claims of the maker......Attempts to slide along Occam's Razor are chancy at best....

    Carbs - good, you get that....

    Nothing new in your post! Paying money for something you can do with things in your home. Kinda dumb, don't you think? Especially for some products.....

    I've read that too but here's what I don't understand.
    when you use it in bloom, you shouldn't use it during stretch phase/initial 12/12 onset
    then you shouldn't use it for last 2 weeks because it interferes with ripening

    so basically, you only use it during middle 4 weeks? assuming 8 week strain.

    Yup.....No use during the last 2 weeks.

    I found that the last few days of stretch was ok to fire up.....Least that's what we settled in on...
    The stretch is more of a personal choice. BUT, yeah, your right!

    I bought Alaska liquid fish fertilizer recently from Home Depot and there was no seal on the cap. I wondered if it would be tampered with. Gross stuff to consider diluting. :spew:

    i always get scared when i use that in my veggie garden. can't imagine that smell won't bring in bears from miles around

    I augment c02 in flower with dozens of different strains of varying maturity full time @ lights on.
    Some are first day in the flower room some are ready for harvest yesterday.
    If I dont.....my experience suffers. (of course, in my sealed room right)
    using C02 is cheaper, easier, less stressful, more precise than exchanging air here, for me and
    after my own comparisons since 2009 I know I made the right choice with it.
    I have no concerns with stretch, hermies, C0, 02 depletion.

    My recipe for minimizing stretch;

    Allow vegetative plant to attain sexual maturity before initiating flower
    Keep flowering plants as close to the light source as possible without causing harm to it.
    Add controls like AC, dehuey, heat, air flow/exchange for full time atmosphere control.
    Sometimes stretching is good momma, I often put a plant under the highest light when initiating flower.
    This is fun with a mature multi topped vegging bush, when these monsters stretch(I have 11' ceilings!)
    they build trees of bud.

    Well that’s backwards. The only argument about growth and co2 is that it may not help after about 3-4 weeks in flowering.

    Some growers disagree and run to the end but larger plants faster is the way to bigger yield so supplementing in veg is jars as important to final results.

    I couldn’t find an excerpt from ed Rosenthals book for free but this page from Grow weed easy has all the correct info.

    The only thing missing is the amount of co2 needed for different light intensities but I found earlier when reading 600 w hps can use up to about 750ppm. And no need to supplement below 250 watts. At sunlight levels our plant can use up to 1500ppm. So a bare 1000 watt de hps for example.

    As the light intensity goes up temp and co2 levels can also.


    I was wrong earlier about how much light before cannabis can use more co2. I was quoting how much for 1200 to 1500 ppm.

    i notice you don't mention lighting

    does keeping lights more blue-ish help during stretch?
