Yes, I agree, I already own HPS thats why I would use them If I needed the extra heat, instead of running an electric heater.
Well you will be quite surprised how parallel the two types of plants are so in saying that there are many important things to consider. Best fitting for the industry would be the use of potassium bicarbonate and or elemental sulphur for controlling powdery or botrytis. The key is the type of product. I use a line called HML32 which has been buffered with a protector (sticker/spreader) to use in spraying solutions. The combo of just those two components (which is hard to buffer) makes all the difference as opposed to potassium bicarbonate on it's own.
My noob advice on biochar: Make your own.
Spend the 41 bucks on some firewood if you cant cut your own for free. Have a campfire with your friends and now you have biochar. Paying to ship ashes hahaha.
Or clean out the barbecue.
Well, life got in the way as it tends to do.Let me start off by saying I am a long time hydro grower.
After reading this section of the forum for the last several months, as well as reading up on organic living soil and the benefits it provides, reading all about KNF and Hugelkultur, as well as listening to a myriad of podcasts devoted to the subject of organic gardening, I have committed myself to moving to organic no till soil for my indoor garden. (Also going to build Hugelkultur beds for my outdoor veggie garden for next year using the same soil recipe below. )
I bought 2 bales of black gold peat moss, 60 lbs of locally sourced ewc, and 2 KIS organics amendment packs. I've got 10 25 gallon smart pots on the way (going to use 8 for my grow). I'm going to reuse the medium I've been growing hydroponically with for aeration after I rinse it really, really well to get rid of any excess salts. Or I may buy new and save myself the trouble of cleaning it. Still undecided.
I still would like to source some biochar locally if I can. Otherwise I'll buy a cubic foot of Black Owl and pay the ridiculous shipping fees.
I am building carts for the bags on casters to make them easier to move about the room next weekend. Going to add a bit of plastic sheeting to the bottom to create a pseudo run off tray on the cart. Once the carts are built, I'll make the soil and start cooking it. Probably take cuttings the following weekend so they'll be ready for the soil when it's ready to be used.
Also going to build a DIY tea brewer. I've got 3 air pumps that would be collecting a whole lot of dust otherwise that I can put to good use.
That is the plan so far.
