An improved tubular seed collecting device comprising a funnel-shaped base which protrudes into the tubular space of the device. The seed collecting device has tabs on its legs and/or elongated bosses on the inside wall of the cup. The tabs serve to limit the insertion of the legs into the plant growth medium to allow horizontal growth of the plant under the level of the cup. The tabs and the bosses improve the air flow through the device. Sturdier leg design allows more re-use of each device.
