You're fine as the other poster's have said, and I used the exact same peat pots for my first white widow grow attempt. Attached are what they looked like at 3 days, then at 25 days, from sprouting. I just dropped the peat pots into 3 gallon pots deep enough to bury the skinny stems to about 1/4" below the cotyledons, then kept them quivering lightly with a fan to toughen up the stems. Worked a charm, although only 1 of the 3 was a female in the end (she's 42 days old today and 12 days into flowering).
