Botonicare nutes

promix is good stuff... hp, bx the "+" of each.. all essentially interchangeable, so you can shop by price. I'd suggest adding enough perlite to bring the percentage up to 50% of total volume. The hp comes with 25%? So, you need add 2 parts promix hp+ with 1 part perlite to get it around 50%. If the promix isn't loose, you need to break it up. The 3.8 cu ft bales expand to 6-7 cubic feet. So 2 cubic feet of perlite pairs well enough with that 3.8cu bale. the smaller 2.8 cu. ft. promix bales are loose, i believe. 1.4 cu ft of perlite would be wise. Don't be afriad to use any "soilless" medium. The fertilization will be the same. fertigate each time and religiously get 10% runoff waste. Get that waste water out of there one way or another, don't let it sit in its own dribble. Fertilizers are essentially commodities. This means there is very little variance in quality. There are different sources for the individual nutes your plant will require. Some companies have better ratios than others. 1-1-2 NPK 4-2-1 KCaMg These are heavily rounded, loose ideas. those ratios at 1.3-1.5EC, regarldess of hydro/soilless nutrient lineup you buy, should work well. Observing and adjusting is always needed, but once you do you'll more quickly find that good balance with a better starting point like this. My vege formula is something like in PPMs (rounded) 125 N 60 P 185 K 110 Ca 75 Mg 100 S It's roughly 650 ppm calculated from guaranteed analysis labels. I have fairly hard water at 300ppm out of the. So, I'm getting "something" from tap water too. Many reasons why it may be slgihtly different but still very similar in your garden, regardless of products used. Been using softened water lately, but formula needed no adjustment. my weighted average of products used in vegetative phase is certainly not 1-1-2 NPK or 4-2-1 for KCaMg, like i said just a ballpark NPK 7.5% / 8.2% / 13.1% K-Ca-Mg 13.1% / 6.7% / 4.3% There are online calculators. Track this stuff.. be consistent with it instead of flip-flopping. Only react to symptoms. The learning curve will be shorter if systematic about it. The beauty of soilless is providing nutes ondemand at the best ratios and concentrations at all times. It is why growth is so much faster than soils. The nutes should be 100% chelated / plant available immediately. Better products will be pH buffered and balanced to a good spot on their own. Fertilizer should be cheap. High prices are pure smoke. Can always look at the ingredients of some high priced magic, then find the same exact thing elsewhere much cheaper. Like generic Rx, if it's the same ingerdient it's the same molecule for molecule. research based hydro nutes: A base with ratios around 5-12-26. calcium nitrate 15-0-0 (15.5-0-0 exists too) and epsom salt Southern Ag, Jacks hydro, masterblend all have a "base" of a similar ratio. All are paired with calcium nitrate and epsom salt to balance it out. The less exploitive versions put the micronutrients (B, Mb, Mn etc..) in the part A, that way you can buy the generic calcium nitrate. The cheesier manufacturers put those in the calcium nitrate, which forcs you to pay an extra 10-20 usd for a 25lb bag. yeah. 25lbs. store in acool dry place indefinitely. If you did 30 plants per year averaging 100day seed to harvest and efficient with water, it's 25-30 usd per year. it'll last 3-4 years. You'll spend the same on the liquid stuff in half a year, maybe a year? anyway, 4 cents per gallon. nothing compares. So, i'd suggest Jacks hydroponic by JR Peters. Hit your first grow out of the fucking park, nearly gauranteed. I'd start at about 90% of their instructed dose and go from there. With any of those brands above, it is no coincedence that their base instructions start at or near those 112 and 421 ratios listed above. It all comes from the same knowledge base. Oh, even the promix hp uses an intial charge of similar ratios. You can check it out. Believe K is a bit low, but otherwise very similar ratios at 1EC concentration. This is plenty to tide over a seedling until your first fefrtiqation. Can just get it wet to start things off with minimal runoff. These ratios work really well and not just with marijuana plants. It's not a secret, but it's also not very popular knowledge for some reason.
