Appellant Roger Franklin Cothran appeals the sentence imposed by the district court pursuant to his post-conviction motion for modification of sentence under 18 U.S.C. § 3582(e)(2) predicated on a retroactive amendment to the federal sentencing guidelines. We affirm.

I.

Cothran was convicted in a jury trial of possessing marijuana with intent to distribute, manufacturing marijuana, and conspiracy. See 21 U.S.C. §§ 841(a)(1) and 846; 18 U.S.C. § 2. Cothran’s Presentence Investigation Report (PSI) attributed 206 marijuana plants to him. ^[1] He did not contest the amount. The district court sentenced Coth-ran to sixty-five months in prison. ^[2] This court affirmed his convictions and sentence. Subsequently, amendment 516 to USSG § 2D1.1 was adopted. USSG App.C, amend. 516 (Nov. 1, 1995). It gives a court authority to modify a sentence under § 3582(c)(2), see USSG § 1B1.10(a), and changes the weight equivalence of a marijuana plant for sentencing purposes from one kilogram to one hundred grams. Id. The amendment was made retroactive by the sentencing commission. USSG § 1B1.10(c).

Seeking to benefit from this guideline change, Cothran filed a § 3582(c)(2) motion for modification of sentence. At hearing, Cothran argued that the 206 plants were the equivalent of 20.6 kilograms of marijuana, and that his revised guideline sentencing range was now twenty-seven to thirty-three months. The district court disagreed, reducing Cothran’s sentence, but only from sixty-five to sixty months, the statutory mandatory minimum for offenses involving one hundred or more marijuana plants. 21 U.S.C. § 841(b)(1)(B)(vii); USSG § 5G1.1(b). ^[3]

[*1562] II.

On appeal Cothran contends that the district court erred in refusing to re-examine the number of marijuana plants attributable to him at resentencing. ^[4] He argues that, under the plain language of § 3582(c)(2), referring the court to consider the factors listed in § 3558(a), the district court is authorized to conduct an evidentiary hearing to consider new evidence on issues of fact relevant to the retroactive guideline amendment.

The Government contends that the district court has discretion under § 3582(c)(2) whether to modify a defendant’s sentence at all, United States v. Vazquez, 53 F.3d 1216, 1227 (11th Cir.1995), and that the factors listed in § 3553(a) merely inform the court whether to exercise its discretion or not. Further, the Government argues that a § 3582(c)(2) resentencing is not a “full-blown” resentencing proceeding but merely a form of limited remand. The Government claims that 206 plants, uncontested by Cothran at his original sentencing, are now the law of the case.

III.

While we have not yet addressed this issue in this circuit, others have. They are in agreement that § 3582(c)(2) and related sentencing guidelines do not contemplate a full de novo resentencing. See United States v. Adams, 104 F.3d 1028, 1030-31 (8th Cir.1997); see United States v. Torres, 99 F.3d 360 (10th Cir.1996), cert. denied, — U.S. —, 117 S.Ct. 1273, — L.Ed.2d — (1997); see United States v. Breen, 928 F.Supp. 977 (D.Alaska), aff'd, 103 F.3d 141 (9th Cir.1996).

A court’s power to reduce sentences under § 3582(c)(2) is discretionary. Vazquez, 53 F.3d at 1226. The district court may reduce the previously imposed sentence “after considering the factors set forth in section 3553(a) to the extent they are applicable, if such a reduction is consistent with the applicable policy statements issued by the Sentencing Commission.” 18 U.S.C. § 3582(c)(2); see United States v. Brown, 104 F.3d 1254 (11th Cir.1997). A court should “consider the sentence that it would have imposed had the [retroactive] amendments) to the guidelines listed in [USSG § 1B1.10(c)] been in effect at the time the defendant was sentenced.” USSG § 1B1.10(b). In determining the amended guideline range under USSG § 1B1.10(b), the court shall substitute only the [retroactive] amendment ... for the corresponding guideline provisions that were applied when the defendant was sentenced. All other guideline application decisions remain unaffected. USSG § 1B1.10, comment, (n.2) (Nov. 1,1994).

This case is not unlike the Eighth Circuit case of Adams, 104 F.3d at 1030-31. In Adams, federal agents discovered 110 marijuana plants on property owned by Adams and his wife. In accordance with a plea agreement, Adams was charged with the manufacture of seventy-three plants and his son was charged with the manufacture of thirty-seven plants. Adams was sentenced to thirty months in prison. Id.

Subsequently, Adams filed § 3582(c)(2) motions urging the court to reconsider his sentence in light of amendment 516. The district court denied both motions asserting that “[h]ad the defendant been held accountable for the entire 110 marijuana plants, the statutorily required minimum term of imprisonment would have been five years.” Id. at 1030.

Finding error, the Eighth Circuit remanded for resentencing, stating:

We ... believe ... that the district court was bound by its previous determination with respect to the number of marijuana plants that was relevant to Mr. Adams’s sentence. In the first place, although the finding is perhaps not technically res judi-cata, it is unusual, for efficiency reasons if no other, for trial courts to revisit factual findings. In the second place, the district court had already made a finding that the[*1563] seventy-three plants for which Mr. Adams was going to be held responsible “adequately reflect[ed] the seriousness of the actual offense behavior,” else the court could not have approved the reduction in the charges against Mr. Adams at all. See USSG § 6B1.2(a). In the third place, the sentencing guidelines direct a district court in situations like the present one to “consider the sentence that it would have imposed had the amendment! ] ... been in effect” at the time of the original sentencing. See USSG § lB1.10(b). We think it implicit in this directive that the district court is to leave all of its previous factual decisions intact when deciding whether to apply a guideline retroactively.

Id. at 1030-31 (emphasis added).

We conclude that the district court was correct in declining to re-examine the number of plants charged to Cothran. Coth-ran received all to which he was entitled when the court, within its discretion, reduced his sentence to the statutory mandatory minimum. ^[5]

IV.

The district court is affirmed.

AFFIRMED.
