    Exhale CO2 Grow Bags in 4x4 Tent

    I've been doing some testing of the Exhale CO2 grow bags. So far I'm pretty disappointed, because of other bloggers totally false information. Based on what I have seen each grow bag only adds about 100 ppm CO2 after 1-2 weeks inside of a CO2 tent - when the plants are SMALL. Once the plants...

    LED vs HPS and Indoor vs. Greenhouse Growing - looking for add'l feedback

    Okay. Jeez you guys are passionate :) Right now I'm running about 80% red/blue and achieving the same max growth rate i can get with sunlight. Basically proves that yes - we need Yellow/Green in addition to Red/Blue to hit the max growth rates. However I wouldn't agree that true sunlight...

    LED vs HPS and Indoor vs. Greenhouse Growing - looking for add'l feedback

    My main background is growing in greenhouse (hydroponic tomato and also in soil for cannabis). Previously we grew around 2.0" to 2.5" of growth per 24 hour day/period in our greenhouses in Colorado (May high light) without CO2 augmentation. Our greenhouses (diffused sunlight) even during May...

    Compost for marijuana?

    FYI - soil/fertilizer labeling requirements for N,P,K are for "soluble" and available immediate nutrients. Organic/Compost N,P,K is normally much much higher in Total Nutrients (which includes short-term available plus long-term available nutrients). Pretty much you should at least triple the...

    Compost for marijuana?

    There's some good and bad information here. Yes, it partly depends on what bacteria is composting the material for the by products produced during composting. However if your growing in the soil/media with fresh compost - phytotoxic element producing anaerobic bacteria will get in there no...

    The truth about PH

    It depends on what you are adding with your tea. Most tea catalyst/formulas add P, K, or Ca or all of them. If your soil is maintained at a certain pH prior to tea application - then the tea can/probably will increase the pH because of the nutrients. If you are talking about modifying your...

    The truth about PH

    pH affects plant growth differently in hydroponic, peat, coir, and compost. 6.3 - 6.8, and even 7.0 pH should be fine in soil and give better yield results unless your macro nutrients are unbalanced. If you have an over abundance of P and Ca (the ratios are wrong vs. K and Mg), then the higher...

    Seedlings in 2 different mediums and drying at different rates, What to do?

    The Organic Mojo is stronger than advertised also (acts different than peat though because the nutrients are all organically derived). It is comprised of compost, and because of soil/label restrictions we decided to under advertise the content just to make sure that the government doesn't ever...

    No clue what soil to buy

    Mojo holds moisture about 30% longer than peat/perlite (peat that has commercial wetting agent applied) under high intensity light and greenhouse growing. There isn't a wetting agent added to Mojo - it is because of the microbiological process whereby there is 30% water chemically bonded to the...

    MojoGro soil question

    Mojo works well adding to peat/perlite mix for indoor. It is a little to strong for jiffy pot rooting - unless you irrigate with water only for the first couple of weeks. I'm attaching a photo of Mojo at 30% to peat/perlite of 70%. Only straight water for first week. Subsequent weeks added...
