The problem lies in the non perlite part of your soil becoming non hydroscopic. Ive heard of people using as much as 50% perlite in their soiless mix but i wouldnt suggest such a mix unless you understand why youre using that much and how you will feed the plants with so much inert material that provides very little retention of anything. A wetting agent or surfactant will do exactly what you are looking for though. The yucca adds the benefit of also giving the microbes in your soil suttin yummy to munch on.
What is your growing medium/nutes? Synthetic or organic? Either way id still suggest going with a yucca as its natural.
Just curious as to why only every 3 or 4 weeks? I use it every time i feed and sometimes add it to waterings
Did you look into the npk industries raw line?
Scott from nectar for the gods says the microbes actually like it! I run nectar and had been using hygea hydration but switched to the npk yucca. A qt of hygea at 20$ was good for about 125 gallons. An 8 oz pouch of the npk for 30$ is good for like 2-3000 gallons! (Or something ridiculous!) way more economical. My theory behind using it as often as i do is to help assure all of my medium gets saturated and i figure if the microbes like it then ill feed it to them! By the time my girls are in flower the root mass at the surface is so dense i cant stick my finger in to check the depth of moisture. Its like poking a firm gym mat but takes water fine. I just cut down a clone i flowered to sex and just let her finish out. Prlly pulled a little early but was in the way! I always check out my root ball wen i take a plant down, like to see whats going on down there. "Pound for pound" the best root mass i have ever produced on a plant! I attribute it to good overall health both physically and microbial paired with a medium that would give and take water willingly.
Found a seller, prices
Seriously? You don't cover the top of your soil with the clay media used by hydro growers and others using soil? You can water without worry, and it helps to keep a good distance between plant and anything growing in the soil that could threaten your plants (gnats, and other buggies). https://www.amazon.com/Leca-Clay-Orchid-Hydroponic-Media/dp/B004IAM29K/ref=sr_1_6?ie=UTF8&qid=1499096496&sr=8-6&keywords=hydro+balls
Maybe i got the 2 oz pouch? I forget. It is pretty concentrated, 1/16-1/8tsp=5 gallons. I weighed out a 1/4 tsp (appx .7g) and mixed with 10ml of distilled water to get 1ml/gal. Im going to look into the bio wetter. I went with the npk because its 100 times more economical then the stuff i was using. Whatever works!!!
Dosnt seem like its that concentrated. 1-2 ml per liter? The bottle pictured on their website is 250 ml. At the concentration im using, there is enough raw powder to make 3.2 of those bottle only it would be 1-2 ml per gallon So closer to almost 10 of those bottles. The raw may be £7 more up front but is by far less expensive in the end. Again, whatever works. Just confused as to how you came up with the plant magic being less expensive. Powdered nutrients are almost always going to be less expensive than a comparable liquid form. Youre not paying for water! It will also have a much better shelf life.
yucca is a safe organic wetting agent raw soluble yucca check it out lasts forever aswell
No problem, glad to help!
