Op doesnt NEED a flowhood, it would be nice they work great, but if op is just starting out trying to learn sterile technique and how to pressurecook then its probably too early to drop money on pro gear. Glove boxes work great, dont nocc em

lol see what i did there.
Also. Did you start with a spore syringe? Maybe everything went to the bottom on your slow jars. Theres alot of possibilities.
Can you provide pictures please? And explain you innoculant and how much per jar
