I got mine at Tejas Mary Jane. It's got a big mold (7-10grams) and a smaller one (3-5grams). Just grind up buds and pack it down really hard. Alot easier than fkn around with a bunch of string and a skewer
I have a cannagar press. I've tried wrapping them in fan leaves a couple times. Both times the leaves ended up crispy and cracked easily. Had to wrap them with a blunt wrap to smoke them.
I grew out 2 of the purple canyons. 1 of mine was also very airy and larfy. The other was great. Smelled like a bowl of freshly cut strawberries. Cured out to a berry with a bit of gas smell. Real nice smoke. I have another going now, but she's only a couple weeks from seed.
There's a SIP thread here full of great info. @Greenthumbs256 has a thread going on using probiotics in his SIPs too. Definately worth a read if it's your first grow using them.
I asked about aerating an em-1 res over on probiotic farmers group on fb. I was told by alan adkisson and a few others (who i don't think ever tried it) that the o2 would kill off all the anaerobic microbes we want. Curious to see how it works out for you.
I use a bamboo skewer. Kind of like a car dipstick for checking oil. It works okay. I believe @Tim Fox made one with a hose and grommet that's alot easier to see when filling up the res.
