got a question man. last grow season i posted a thread about keeping animals away. u suggested bitter yuck. should i spray that directly onto the plants or around them? im also gunna try high strenght fishing line and cayenee peper. does cayenne pepper really work? thanks bro

take some plastic lids from like a butter container or something & cut them to size & cover w/ tape, then poke a few small pin holes in it.

spray it on & around plants, also peeing around the area of plants every few days will keep deer, rabbits, etc away. not sure about the pepper, i know garlic powder (unsalted) works, also look into neem oil.

preciate it man. ive heard of neem oil being used for that before. im not really sure were to find it. you think it would be in a regular gardening store like where i get my soil and ferts? or is it more possible to go online?

ive seen it time to time @ lowes or homedepot in the garden center where the ferts & pest stuff for roses, & other plant stuff is, u just got to look pretty good for it

To figure out the ppm of your fertilizer (or fertilizer mix), you need to be able to measure grams (to a few decimal places unless you are making a lot of solution) and liters. Look at the numbers on the back of a fertilizer bag.

The pitfall to be avoided here is that the fertilizer manufacturers list some of the nutrients as their oxide, like K2O for potassium and P2O5 for phosphate. In the 'guaranteed analysis' there will be a list of compounds, and elements and their % content (supposedly, see conversions below).

For every one gram of said fertilizer in one liter of water, it contributes 10 ppm of the given nutrient per percentage point. A 20-20-20 gives 200 ppm (10 ppm X 20) of each nutrient for each gram in a liter of water.

The formula:



grams of fert per liter = A/B

where;
A=your desired ppm
B=10 ppm X the %(not in decimal form) of nutrient in mix

or

your ppm = C X B

where;
B=10 ppm X the % of nutrient in mix
C= grams of fert per liter

To convert from compounds to elements:

P = P2O5 X 0.44
K = K2O X 0.83
Mg = MgO x 0.60

You'll need to determine the Ca source to determine actual soluble Ca content:
Ca = CaCO3 X 0.4 for calcite or soluble Ca source
Ca = CaCO3 X 0.23 for dolomite

This is important to know, because the method the fertilizer manufacturers use to label the bags overstate the actual content. This is just the way they label the product, and says nothing about what form the nutrients are really in.

So, to make a 200 ppm N, 100 ppm P, 200 ppm K mix using a 13-0-44 (potassium nitrate), a 12-62-0(monoamonium phosphate), and a 33-0-0 (ammonium nitrate) you would work backwards from your sole P and K sources (it makes it easiest in this case), and make up the N at the end.

You would use 0.55 g of potassium nitrate (200 ppm/(10 ppm X 44 K2O X 0.83)) and 0.37 g of monoammonium phosphate (100 ppm/(10 ppm X 62 P2O5 X 0.44)) in one liter.

This would give you 116 ppm N (10 ppm X 13N X 0.55g + 10 ppm X 12 N X 0.37 g), 101 ppm P (10 ppm X 62 P2O5 X 0.37g X 0.44), and 201 ppm K (10 ppm X 44 K2O X 0.55g X 0.83). 84 ppm are needed to raise the N to the 200 ppm level, so we can use 0.25 g of the ammonium nitrate (84 ppm/(10 ppm X 33 N)) to bring us up to finish.

The actual mix would yield: 199 ppm N, 101 ppm P, 201 ppm K mixture in one liter of water. To get more precision, you need to mix larger batches or get a better scale (you would need to make a 100 liter batch of the above with a scale that is only accurate to the gram).

If you mix your own ferilizer, you can adjust your N source to meet your pH needs (see the FAQ), rather than being dependant on adding acid or base, which is nice.

This works for formulating hydro mixes, as well as for us dirt farmers

did u ever get that MK going??

i put them outside & 3 of the 4 lived w/ 4 more outside (6days old), started some more, 7 dif strains. 2 big bud, 2 nl #5, 2 white widow, 1 fem the church, 1 fem big bang, 4 fem master kush, & 1 fem skunk special

When to harvest? if you cant see the trichmomes, but the white hairs are turning red, but really cannot see the trichomes..
so do i harvest when all the white hairs have turned red? it's 9 weeks old, but a very early flrwg plant, mutant i suppose.

u can get a mag glass cheap @ many places needs 10-30x (30x better), or radioshack has a pocket microscope for 10$. go by these pics.


below is pocket scope from radioshack

Hey guys quick question for you's, Ive been watch in my yard for the best spot to put my plants and i was wondering if morning sunlight is really that much better for the plant then like afternoon sun into sunset?

[ocitown]

JCJ; My clones now under the 1K are about 5 weeks old and ~20% of the white hairs are turning red,only 8-10" tall but all one bud stalk and looking real nice. I figure another 2 weeks of several AN sups and then 2weeks of pure H2o then a trim and 10 days of upside down darkness to dry and into the air tite jars to cure. Each mini plant should give 1/8-1/4 of great smoke.

anyone know how to get rid of the little brownish yellow spots?
ferts?
nutes?

the brighter & more sunlight there is, the better it is. more light = faster, bigger growth
