This thread blew my mind.
to get back to the op question,silica may help with your pm problem if used as a foliar but just adding it into your res after you see signs of pm will not help imo.and plants dont really use up SI like they will other nutes like NPK so just adding it in 1 x a week during veg and bloom is enugh to see the benefits. i use it about 1 x a week as my ph up because most silica products raise ph alot,more so when using r/o water.if your pm is just on a few spots,remove those leaves carefully.give your plants more space.crowded rooms are always at higher risk for pm.and try to keep your r/h levels from big swings.like if your growing in 60% r/h lights on try to keep it there during lights off.and keeping the temps closer helps also.run your room at 74-76f lights on and 72-74f lights off,it will help stop the spread of pm.sulfer burns will knock it right out ,if your not close to harvest that would be my first option.copper soap fungicide as a spray will kill the shit also.theres alot of threads here on it,people use milk and water to foliar with good results also.gl
What's the aloe for?Can't speak for use in a hydro system , I'm a soil grower , but I do use it. I use it every watering at 5ml per gallon throughout the plants life and I notice a Difference in stem strength and overall plant health. I also use it in a foliar spray in combination with fresh aloe weekly
I also heard there is some truth in it helping with PM but don't quote me. I know gardeners and Some smaller scale organic farmers use horsetail tea as a preventive to PM on squash and other veggies. Horsetail is loaded with Si so there may be a connection. I'm Just thinking the Si makes plants stronger and more resistant. If you decide to use it as part of your program look into Agsil16h and just make your own concentrate. I think I spent $13 on the powder silica and it makes a few gallons of concentrate, it's really cheap and your not paying for water

RHINO SKIN for the win!!!I'm prob going to get pro tek or silica blast, did the research years ago and can't remember which came more highly recommended.
Any recommendations?
Ur right .Silicon dioxide mostly. I detest spiders. My wife is pregnant and avsolutely gags at the smell of neem oil, so this seems to help keep the lil F'ers away from my MEDICINE!!!i bought some diatomaceous earth super fine grade, its silica powder. Put a dusting towards bottom and on surface of me coco pots to stop any bugs insects from attacking, i read it cuts em up like glass. i sprinkle the leaves also a little in veg. Cost me about $50 for 4 kilos so its pretty cheap and i mix alittle in me orange juice from time to time and drink it suppose to kill stomach parasites and what not.
It’s a organic stimulant.What's the aloe for?
